Global plasticized mesh http://www.pvc123.com News : Careful find plastic everywhere, with the improvement of the technical level , rigid plastic , impact resistance, creep resistance, chemical resistance , etc. have breakthrough improvement , while according to user needs, customize or add different properties, such as electrical conductivity, heat resistance. Plastic has become the core of most of the material composition of plastic packaging design electrical and electronic products . It is understood that in the appliance industry , the plastic products industry has become one of clear plastic packaging the important development direction of pvc tray home appliances , plastic household appliances have become the plastic box design application of the amount of material the fastest growing in recent years, an annual average growth rate of around 29.5% .

Development of plastic materials technology has created many new opportunities for the manufacturing sector plays a pivotal role in the world of electrical and electronic products industry, but also to promote the electrical and electronic industry as a whole move to a new level .

In modified plastics , for example, a lot of additional performance make it more in line with the needs of a variety of different electrical and electronic products. Typically by adding different ingredients to achieve the plastic material clamshell packaging flame retardant, transparent , weather purposes. Can be applied in racks inside the barrel drum washing machine , microwave seal, trumpet speaker , speaker stand, refrigerator , rice cooker shell and base . For example , Bayer PC material , Victrex PEEK high performance plastic materials have a large number of applications in the electrical products. Plastic insulation is also the main reason for electrical products to become part of the raw materials . plastic packaging Many types of electrical and electronic equipment , requirements vary, plastic insulation requirements are not the same. Heat resistance and environmental adaptability insulating plastic electrical equipment in high temperature environments powered extraordinarily important. Electrical equipment in the connector , AC contactors, switches , junction boxes , plugs, sockets and other parts of a large number of the applications.

With the advent of SoLoMo (SocialLocalMobile) times more electrical gaming is about to become human hands , you can send a signal via cell phone before going home to home ” in control” , after sorting signal , household appliances are the divisions its your job to fulfill their tasks . If you do not want to let the house become a dragnet of silken web , signal reception and transmission of wireless technology will become the best choice. So start thinking more appliances implanted antenna .

Supplied by SABIC LDS ( Laser Direct construct ) is the use of a plastic material additive the material is easily activated by the laser plating performance of the antenna module with the original conventional plastic housing skillfully combine to make the product available space larger , more in line with the aesthetic appearance and ergonomics . The technology has been widely used in mobile phones and other handheld plastic packaging box devices manufactured .

Relevant statistics show that global demand for electrical and electronic products for plastics increased from 12.2 million tons in 2005 to 15.6 million tons in 2011 , a compound annual growth rate of 4.2%. With a variety of plastics in electrical products increase application volume plastic trays , a true era of plastic electrical and electronic equipment . I believe plastic chemical applications will be more widely , to bring more convenience to our lives.

Our meat production since 1990, has been ranked first in the world, but the proportion of deep processing of meat products, meat production accounts for only 10 percent of the world’s developed countries generally have reached the proportion of about 50% in some countries even more than 70% , with a considerable gap between the advanced level . More importantly, the variety and quality of the meat is more behind the world ‘s advanced level , one of the key reasons is related to meat packaging technologies, mainly developing flexible packaging technology.

Nearly 30 years of experience in the meat industry, secondary larger development. The first time was in the early 1980s began , with the meat then the introduction of foreign advanced processing equipment and technology , led to the packaging of frozen meat division and the development of Western-style cooked meat ; second was from the 20th century, 90 start early 1990s decade , there has been a small package division chilled meat and sausage and meat products as the representative of Chinese products development.

In the 21st century , under the new situation of joining the WTO , China’s meat industry will be faced with yet another new period of development during this period in the development of the meat industry is not only reflected in the volume , but the main purpose is to reflect in terms of quality , high-quality, safe and secure meat products will continue to emerge , cold meats, fermented meat products, meat products , such as Chinese industrial production of high -tech new products will be the future direction of development.

Throughout the history of our meat products are all closely linked with the development of packaging technology , which is mainly associated with the flexible packaging technology , the meat industry ‘s technological innovations needed to support flexible packaging technology , whereas the emergence of new flexible packaging technology also contributed to the meat industry development. In the second period of development in the past , many domestic flexible packaging technology and equipment development lags behind the needs of the development of the meat , so that the domestic flexible packaging companies lost a lot of opportunity to make a considerable number of imported packaging materials and packaging machinery and equipment occupied the domestic market. The purpose of this study is to remind the domestic flexible packaging industry engaged in various aspects of attention, to avoid further missed opportunities facing Third , speed up technological progress and product development in the flexible packaging industry , the third major development to meet China’s meat industry. The following two aspects of the new fresh meat and meat products are as flexible packaging technology and its development direction of the relevant meat

Flexible packaging fresh meat

China is expected in the next 5-10 years, meat production will be 5% -10 % annual growth rate continues to grow. Chief among these is the development of fresh meat , fresh meat, how flexible packaging technology to keep up with this development is an issue of concern within the industry . Flexible packaging raw meat meat consumption is mainly to solve the safety shelf circulation problems . Meat slaughtered pigs , cattle and other live will produce a series of biochemical changes , the end of the period clear plastic packaging to maturity from stiff , quality of the meat is constantly changing, if not take a scientific package shelf technology , raw meat quickly would spoilage. Requirements for fresh meat shelf life , at home and abroad with a frozen, refrigerated , irradiation sterilization , chemical corrosion, vacuum packaging , inflatable packaging, packaging and shelf combination of technology .
The plastic packaging design early 1980s, China’s market accounted for a large proportion of frozen meat was introduced many advanced segmentation packaging frozen meat equipment and technology , the main packaging material is a single layer of polyethylene bags beginning , and later developed into nylon / polyethylene composite flexible packaging bags , packaging forms from simple to complex single- film plastic bags and vacuum-packed bags of soft film forming vacuum packaging. In addition to the domestic packaging equipment vacuum sealer, the introduction of the soft film forming filling and sealing machine (FFS machine ) is the most advanced flexible packaging equipment. Packaging products are mainly divided small package frozen legs, big row , a small row , meat and other products , which meet current market demand for play a role . But then the fresh meat at a low level overall flexible packaging , vac tray packaging materials polyethylene film mainly due to the water vapor transmission rate of large polyethylene material , frozen in dry- period consumption saving big bag severe frost , poor appearance and form of packaging , printing and decorating rough most of the products , so our 80 years of frozen raw meat packing group including lower commodity level.
Cooked meat flexible packaging
Cooked meat with rich protein , microbial very easy to breed , and storage of fat in the meat products easily oxidized , so the key is cooked meat flexible packaging technology can extend the shelf life of the product , to ensure food safety and quality .

Our Chinese cooked meats cooked meat can be divided into two categories and Western cooked meat , cooked meat over Chinese industrial production and packaging technology is relatively backward , products are divided into the traditional sauce stewed , grilled , bad drunk class , Western-style meat products higher degree of industrialization , the main products well- leg , round leg -based products as well as Western-style ham sausage , small sausage -based plastic trays products and bacon sausage , salami and other Western products ; dried products and other varieties . Due to the different types of products the processing conditions and shelf life requirements, these flexible packaging in the form of cooked meat and techniques vary, the following main cooked meat flexible packaging technology introduction.

1 . Cooking bags and canned soft packaging

Country in the 1970s began to use cooking bags, soft canned cooked meat and other research on packaging technology , soft canned material mainly consists of PET / AL / CPP three composite , and transparent retort pouches from PET / CPP or PA / CPP based. As good canned soft barrier properties of aluminum foil and dark , soft canned meat vacuum-packed can be stored at room temperature for 6-12 months after high-temperature sterilization . Plus convenient packaging to carry, easy to open , so there is a certain consumer market , the product has a knuckle , chicken , duck and other Chinese traditional meat and poultry products . Due to the high temperature sterilization , the flavor deterioration , texture Sulan , canned flavor is cooking bags and soft canned a common problem , to some extent, limit the development of such markets packaging products . PET / CPP or PA / CPP Layer retort pouch transparent clamshell packaging material of the barrier is not high , the packaging of meat products susceptible to oxidation deterioration , the shelf life is not long . Currently transparent high barrier packaging materials is the focus of international development , such as MXD6 nylon , EVOH composite film and silicon oxide (SiOx) film deposition development series , so that the display and protection of goods greatly improved, ultra-high temperature sterilization development and application of high pressure sterilization and irradiation , microwave sterilization and other new technologies to provide useless for the application of these materials , we should pay attention to the development of these good transparency, high barrier flexible packaging material in the gaps .

2 . Aseptic packaging and semi- aseptic packaging

Aseptic packaging and semi- aseptic packaging technology first developed in the Western-style meat products, using sterile flexible packaging materials , in the sterile environment of processed meat products after sterilization packaging can keep food in the maximum the original flavor of the product under conditions of low flow of Western-style round legs, square legs and sliced ??meat products due to the aseptic processing of solid Western food more difficult, so they plastic packaging box use a semi- aseptic packaging technology , packaging materials EVOH, PVDC , composite materials PE, PA , etc. made ??of co-extruded high barrier multilayer film or sheet , such as sterile , shrink film also use more complex in sterile packaging. Chinese meat aseptic packaging , semi- aseptic packaging technology needs further development and research . Such technology breakthroughs , will remain authentic Chinese meat flavor, extend shelf life, has a very broad application prospects .
3 . Pasteurization packaging

The next few years China plastic packaging will vigorously develop the low-temperature meat , which is a key technology LTMP shelf technology , low temperature meat products due to maintain maximum nutrition and flavor , more favored by the market .
One of the key LTMP shelf packaging pasteurization technique is that the product again after heating pasteurization rapid cooling after packaging to eliminate microbial contamination in the packaging process . Such meat packing applicable to most of the Western meat , high barrier flexible packaging material composite film and sheet transparency based, and can heat sterilized by heat-shrinkable materials will also be pasteurized there are a very wide application , in addition to vacuum packaging, a high degree of mechanization and automation of forming a sealing system of a filling will be a great development.

4 . Sausage packing

80s polyvinylidene chloride (PVDC) -based film casings filled with sausage , ham processed by high-temperature sterilization appeared in China began to develop during the 1990s unexpectedly to occupy half of the domestic meat production of competitive products , however, PVDC sausage and ham filling packaging machine punch card but rely mainly on Japanese imports , the introduction of the production line is repeated up to 600 . Ham popularity has its actual market conditions and circumstances , our flexible packaging industry at the time of the missed opportunity , but as a high-temperature meat sausage is no longer the direction of future development, and low-temperature meat sausage casings class flexible packaging , fermentation meat , high salt water expansion products will be the direction of development, technology casings of various man-made fibers , high barrier composite casings , shrink casings and other flexible packaging materials and the corresponding filling and packaging equipment has a huge potential for development.

Outlook

21st century China ‘s meat industry is facing a new development the former , for the flexible packaging industry is full of challenges and opportunities of the timing , the world of great concern to food safety issues , HACCP systems in the food sector in the promotion , plus tech, diversified structure , convenience food of the meat industry for flexible packaging industry put forward new demands , hoping to strengthen domestic enterprises technology investment and new product development in order to meet growing market

Shelf and shelf life extension aspects of food, medicines show a very excellent performance for decades PVDC high barrier packaging materials plastic box as always in a dominant position , although there EV-OH and PAN two materials , but they are in a high humidity environment barrier properties decreased significantly and has not been further developed. Similarly PA ( barrier material can not be considered under the strict definition ) can not replace high barrier PVDC excellent package for contents protection, and usually also need to practice with PVDC coating process to improve its packaging performance .

Biodegradable plastic product development , and then a plastic bag into an advertising vehicle , specifically relying clear plastic packaging on the development of community ads in major markets , the development of Chongqing guy bags advertising , profit margins as high as 50 %.

Usually go to the supermarket to buy food, a lot of secondary use of waste plastic bags are made ??of . Now Chongqing guy Lee Kirin developed a new type of biodegradable bags .

“The texture and ordinary bags plastic bags the same, but the ingredients are not polyester vinyl , but can degrade the calcium carbonate clamshell packaging and limestone , which can be half a bag on the wild plastic plastic packaging design trays natural degradation , incineration will not cause atmospheric pollution . ” Lee Kirin said that if the same price , this health can be degradable plastic bags certainly popular.

So he designed for the small plastic bag a unique business model : advertising. Printed on the plastic bag business information on advertising , promotions and other information , when people buy food , will be used in these ads are printed bags . A vegetable market takes about a month away 150,000 bags , 10 markets was plastic packaging box 1.5 million , a large advertising effect . This model mainly rely plastic box design on government policy support to promote, market franchise markets surrounding communities .

Lee Kirin said pvc tray this advertisement bags distributed without additional cost , the advertising platform is mandatory , as long as people buy food businesses will receive advertising messages ; Furthermore , carrying bags which people can also travel information on the show bags to more people to read. An advertising charges is 700 to 1000 yuan , can be printed on 70,000 bags , each can hold 64 bags advertising. A monthly demand plastic packaging for vegetable market at about $ 150,000 in advertising revenue more than 6000 yuan , profit margins above 50 %. Expected soon people will see this new type of biodegradable bags .

China plastic pipe Deputy Secretary clamshell packaging Wang Zhanjie in Plastics Processing Industry Association revealed that a comprehensive ban of lead timetable plastic pipe being developed , and people ‘s lives will be fully out of plastic packaging design the water pipe ban lead at the end of this year.

A reference to ” lead poisoning ” People always heard discoloration , in addition to violations of food and cosmetics , for decoration of plastic pipes, doors and windows -based materials in this terrible way also threaten people ‘s health. Especially called “urban vessel” out of the plastic packaging box water pipe. Most are made ??of PVC material plastic trays , this kind of plastic products to be produced in the process of adding a known lead salt stabilizer. Deputy Secretary-General Wang Zhanjie China Plastics Processing Industry Association , said in an interview with reporters , although the lead salt stabilizer security risks, but there is no total ban . Wang Zhanjie : PVC pipe is what we do the most successful varieties, better price . However, high temperature PVC can not be decomposed, forming temperature is not low , it added heat stabilizers , the best is lead salt stabilizer , but our lead ban is local , not only in the water supply adding, drains and other pipes did not mention plastic box design .

According to reports, a plastic containing lead salts to the water pipes have been disabled world , national and Beijing construction sector has also made ??provisions disabled . Wang Zhanjie said , will be fully implemented before the end of this year to ban lead pipe order, our industry association is also developing planning table . Since 2015, the European commitment to a comprehensive ban of lead, China should also simultaneously go. To the plumbing in this order, but we never drain under clear plastic packaging this order, the reason is that our current processing costs are too high.

Wang Zhanjie problem description, PVC pipes , in fact, there has been controversy. Just do not lead salt stabilizer , there is no problem. To achieve industrial innovation and technological progress can only help people, but also conducive to the health industry . Wang Zhanjie : If we increase the cost disadvantage on pvc tray this industry , we have to give businesses slow breath . plastic packaging All this will certainly solve the water supply problem to ban lead . This phenomenon is not only today, PVC pipe water from there is the 1980s emerged.

Plastic clear plastic packaging plastic box design products filled with every aspect of our lives we are , but they also have differences in quality plastic products , a lot of poor quality was most likely secondary plastic quality, but off , so when plastic packaging design we buy to pay attention. For plastic plastic packaging box bottles on the market , if we are not careful, will not generally distinguish between the quality of the merits of whether harm to human health. But look , we sometimes find some poor gloss plastic bottles containing impurities , yes, what you see clamshell packaging is secondary materials production of plastic bottles . For these secondary materials plastic bottles on hand to strictly punish manufacturers producing plastic bottles , but more importantly, you want to waste plastics processing enterprises strict supervision from the source, there is no standard for enterprises to resolutely banned. The so-called secondary materials to produce plastic bottles, are some pvc tray of the materials without the rigorous cleaning and disinfection of waste plastic recycling made ??of the production of plastic bottles. These plastic bottles are difficult , whether or plastic packaging standard quality from all aspects of health . These secondary materials have been able to prevail in the market , in its very low price , compared to the new material, the secondary material is not up to even half the price not to. Some manufacturers of plastic bottles in order to reduce costs or to the use of the new compound doping . If the flow of these plastic bottles to food, medicine and other packaging areas , direct access to the Food plastic trays and Drug words greater human harm. He is also on the use of new materials for the production of plastic bottles manufacturers formed the unfair competition , in addition to the production of these secondary materials also tend to form a harsh environment.

The summer of 2013 , a record high temperatures in many cities , and even make people feel difficulty in breathing. Meanwhile , many consumers worry that the high temperature environment using plastic packaging food can ” breathe” , plastics toxic substances released into the food will not go ? Food shelf life will be shortened ?

Food health experts said , as long as strict accordance with national standards of food packaging bags , vacuum bag and other plastic products , its heat resistance is completely safe reassuring. But the point is that enterprises must guarantee the quality and technology related , must ensure that the products meet the national food safety standards. Must also meet the individual needs plastic packaging box of different food characteristics.

First, the individual needs to produce safe food packaging

Plastic food packaging , not only affects the taste of food , preservation status , also affect food safety. Canadian federal Food Inspection Agency has a famous saying: ? Your food safe if you take a look at the packaging it qualified plastic food packaging , food safety before gradually as part accepted by consumers ! .

However, consumers and even some of the food business, how to choose a plastic packaging materials do not know much , into a ” beauty that is safe” misunderstanding. In fact , as many as 100 kinds of plastic types , not all plastics can be used for packaging food , and different foods also need to use different materials to packaging.

Such as polyethylene (PE) bags odorless , non-toxic , has good moisture resistance, low temperature performance, is the ideal material for the production of film preservation , packaging , fruits, food is very appropriate. However, at high temperature polyethylene packaging can release toxic substances, with the food into the body , to induce cancer, birth defects and other . And polypropylene (PP) due to the relatively small bags containing the additive itself , is more stable at high temperatures , can withstand high temperatures 130 , it is more suitable than the other materials used in the water made ??of plastic cups, plastic boxes used for microwave heating , etc. .

Do not focus on the individual needs of the bag , even if the food companies have chosen the material can be used in food packaging, but in hot weather it is easy to lay security risks.

Second, the individual needs to produce plastic products characteristics

? The individual needs of plastic food packaging has what itpresident Chu Nan Haida Plastic Packaging Co., Ltd. Shandong introduction, according to the characteristics of different food , plastic food packaging is also showing different individual needs , divided into five categories:

The first is the need for a soft and transparent, has good performance of water- proof plastic packaging , mainly applicable plastic trays to fear the influx of food ;

The second category is plastic packaging the need to have a good deadening resistance, abrasion resistance, puncture resistance and oil resistance of plastic packaging , mainly applied to greasy foods , snack foods, seafood and frozen food ;

The third category is the need to have good dark resistance and heat sealing, aroma , non-toxic , odorless plastic packaging , mainly used in cooking food , baking food, etc. ;

The fourth category is the need to have a good bactericidal , prolonged periods pvc tray of plastic packaging for food preservation , mainly used in meat products ;

The fifth category is good transparency and gloss , easy to use plastic packaging , mainly applied to dried fruit , spices and so on.

“Different foods have different needs for packaging , food companies only local conditions to select the appropriate plastic packaging materials , in order to avoid unnecessary food safety incidents .” An industry source stressed.

Third, to provide personalized security services Haida Plastics Corporation

Plastic packaging industry is still concerned about the well-known companies have long individual needs , and to develop targeted corresponding product . Chu Nan Haida Plastic Packaging Co., Ltd. Shandong , on individual needs for more than five food packaging were introduced polyethylene plastic box design (PE) bags, vacuum package bag (PA / PE), aluminum composite bag (OPP / PET / PE), high-temperature cooking composite bag (PA / CPP) and a zipper plastic bag (PET / PE) five products , a good solution to the individual needs of food packaging , but also promoted the development of China’s plastics packaging plastic packaging design industry and progress .

Benefit individual needs strategy Chu Nan Haida Plastic Packaging Co., Ltd. Shandong is not only to meet the massive needs of the market , gain the trust and cooperation, including gongs clamshell packaging , 99 ducks and other well-known food companies to take up the China Southern Airlines , China Eastern Airlines and other aviation Aviation food packaging company mission, universally recognized customers ; Chu Nan Haida and the quality has reached the national top standards through clear plastic packaging ISO9001 international quality system certification, 14001 environment system certification, product access to national export commodity inspection and national quality accreditation AQSIQ issued a production license , and has become one of the few number of national quality certification authority of plastic products production and processing enterprises.

In the near future, the social development of plastic packaging will also propose a more diversified individual needs , and we look forward to Chu Nan Haida have come up with a richer product for food safety escort.

PVC plastic film means a film , polyethylene, polypropylene, polystyrene and other resin, used for packaging, and as coating layer . “Twelve Five” period, especially plastic films feature film materials in emerging industries will play an important role , excellent functional properties of thin film materials , the downstream market segments targeted, broad application prospects. Water film solar cell membrane , a thin film flat panel display , semiconductor and microelectronics films will have a vast space. Functional film materials technology barriers, the main difficulty lies in its formulation, process and equipment. plastic packaging Among the many features of the film , the integrated market space and technical barriers , our most promising optical films and photovoltaic films. Optical grade PET plastic packaging box as the main raw material of the optical film , clear plastic packaging diffusion film, a brightness enhancement film are processed on the basis of the slice from plastic packaging design the PET . Due to the high levels of optical plastic trays thin-film technology , a technology-intensive industries, high barriers to pvc tray entry , is still mainly rely on imports. Now there are companies wishing to enter the domestic optical film field , the domestic enterprises to enter the field of optical films , will boost demand optical PET film. Optical PET film production is mainly concentrated in the Japanese and Korean companies , domestic enterprises have yet to achieve large-scale production plastic box design . East wood science and technology , Nanyang Technology ( 002389 ) is expected to lead a breakthrough. Solar films including film and EVA film backplane backplane film mainly made ??of a fluorine -based film and a polyester film. Fluorinated membranes highest technical barriers , China is still not industrial enterprises, the clamshell packaging relative maturity of the polyester film is slightly higher domestic East wood science and technology , Changzhou Yuxing ‘s products have been certified by the downstream large foreign clients , import substitution is increasingly obvious, large southeast , binary new material, Nanyang Technological also actively entered the field.

As one of the four major packaging materials, metal packaging plastic packaging design materials plays an important role in modern packaging materials. Generally , the metal vac tray packaging material has the following advantages .

( 1 ) has excellent barrier properties and excellent overall performance protective metal packaging materials for gas, water and water vapor transmission rate is very low ( almost zero ) plastic packaging box , good aroma and completely opaque , effectively avoid the harmful effects of UV rays ; their gas barrier properties, moisture resistance, shading and aroma far more than plastic , paper and other types of packaging materials. Thus, the metal clamshell packaging packaging can provide excellent protection performance as contents , is conducive to long to keep the quality of the product .

( 2 ) having plastic trays good mechanical properties, workability and high strength metal material having good packing and high strength ductility , can be stamping, rolling, drawing, welding and other processing can be made thin-walled, high strength , unbreakable containers , can also form an excellent overall performance of composite packaging materials and a variety of other composite materials .

( 3 ) has a special metallic luster , surface decoration and good special metallic sheen plus exquisite decoration printing , you can make the product look rich and gorgeous , beautiful merchantability , and can increase the value clear plastic packaging plastic packaging of the goods.

( 4 ) convenience , hygiene and good metal packaging containers and the paint is generally able to meet health and safety requirements , with its packaged plastic box products to carry and easy to use ( generally equipped with easy-open device , such as a ring-pull cans , etc. ) , can adapt different climatic conditions . And waste treatment is better , recyclable recycling.

Although there are many advantages of metal packaging materials , but there are shortcomings , including: chemical stability is poor, especially steel material easy to rust, should generally be coated with anti-rust material ; weak acid , packaging acidic substances ( especially food ) , the precipitation of metal ions affect product quality , generally require isolation to protect the coating ; metal Packaging materials higher than prices of other packaging materials , integrated packaging and higher cost.

Food packaging purposes, mainly to protect the food from the effects of chemical physical and microbiological factors to ensure the nutritional content of food and inherent quality of the same, in order to protect the health of consumers . In addition, packaged food to transportation , storage , sale and use offers many convenient conditions , while promoting the sales. Reasonable food packaging to extend its shelf life and shelf life , to a large extent reduce the tendency of deterioration of food .

Factors that affect food quality : – is light ; Second temperature ; Third oxygen ; Fourth humidity ; ugly microbes .

From food production , distribution and consumption of the three angles together, food packaging purposes : – to prevent spoilage , quality assurance ; second is to prevent microbial and dust pollution ; Third, rationalization of production of food , high-speed ; Fourth, there conducive to transportation and circulation ; five is to improve the food value of the goods .

The food industry is the largest user of packaging design and beneficiaries. The development of the food industry and packaging are inseparable. Sometimes , some of the packaging process can dramatically change the product structure, industrial structure and development processes of the food industry . A typical example is clear plastic packaging the combination of beverage packaging and sterilization processes.

Yun innovative food packaging materials

Due to the use of the paper packaging can be recycled again , a small amount of waste in the natural environment can naturally break down , and the natural environment is not without influence , therefore the world recognized paper, paperboard and paper products are green products, to meet the requirements of environmental protection.

Plastic packaging designed primarily to improve the design , provide more convenience ; improve the structure of composite materials to meet the more stringent requirements ; new product vac tray plastic trays paper packaging focuses on functional improvement. Such as United States, Japan and other countries to develop a pad of paper packaging for fruits and vegetables , can absorb ethylene and carbon dioxide gas released by fruits and vegetables , etc., and developed – some insulation paper, such as anti-corrosion paper – based products . Future development trend is airtight plastic multi-layer composite , functional plastic , biodegradable plastics more rapid development . Our rapid development of biodegradable plastics , such as the potato and corn starch food container plastic packaging design , pulp , vegetable fiber packaging materials, as well as ” light – controlled submerge bio degradable ” plastic, etc. , but the market share is not high, so broad prospects.

With the development of science and technology, food packaging materials and containers have undergone great changes. In recent plastic packaging box years, a variety of new materials and materials processing research and development of new technologies, especially new polymer materials continue to emerge for food packaging offers a vast world .

Newly launched high pressure food packaging, food characterized vitamins, fragrance , pigments and other pressurization will not packaging design change, thus maintaining the natural flavor of the food , and not destroy nutrients . To jam , fruit juice , vegetable juice to the meat , fish , eggs , soy protein can be processed using high plastic packaging pressure . These foods by 400 — 500] ~ A processing, high quality packing material , reasonable packaging design, printing and product color, appearance , flavor similar products are better than the original , although the price is higher, but still deeply consumer who welcome and all ages.

In packaging materials added nanoparticles . To produce the odor, sterilization effect, can improve the shelf life of packaged food .

Is the development trend of green packaging

What is a green packaging ? According to experts, is the ecological environment and human health harmless, no environmental pollution, recycling and renewable energy use can promote sustainable development package . Thus the world’s developed countries to meet the identified package . “4R +1 D” principle, namely consumption, the development of new green materials , reuse , recycling and degradation Division . Experts predict that the next 10 years will dominate the world market often green green green packaging must be actively researching and developing “green packaging” is packaging industry in the face of the new century, the inevitable choice to join the WTO .

Ensure the quality of green food , green food to maintain freshness , is the basic function of green packaging . Therefore , green clamshell packaging sterile preservation, and packaging is the preferred target green packaging .

Green must have green packaging, which has become the new century, a new fashion green packaging , packaging mainstream . Clearly defined government environmental protection departments , the green packaging should be ” four – body ” logo : green flag , the word green text, coding and laser anti-counterfeit labels certification unit .

Lagging behind the level of China’s food packaging

China’s food packaging material is – a growing market , which, especially in the higher growth rate of chemical plastic box polymer materials. Plastics USA , Germany, Italy every year for food packaging into 4.5 million tons , 2 million tons and 1.9 million tons expected this year, China’s food packaging demand up 150 – 200 million tons.

Modern food science and food packaging industry needs , although nearly 20 years , China’s packaging research and development of new materials relatively quickly , but the package works is – Door emerging interdisciplinary, involving a wide range of knowledge , plus packaging and packaging industry started research late, weak economic foundation , China’s packaging technology in general, is still relatively backward, can not fully meet the requirements of the food industry ‘s rapid development . In particular mindset of the people is still relatively old, inadequate packaging and excessive packaging widespread.

Reasonable food packaging should be just right for a protective foods , including physical, chemical , and biological properties of protection is not pompous beautifully decorated , convenient storage, transportation and consumer use.
