Make plastic packaging plastic box design for the food put on the ” helmet”

As mainstream varieties of food packaging , plastic food packaging is playing an increasingly important role in ensuring food security, and improve the standard of food packaging materials is to protect itself safe and reliable important technical means.

Plastic packaging for the food security escort

China Light Industry Information Center, the former race engineer Don Jane believes that food safety hazards are many factors , including the storage and sale of part , due to the lack of a better performance of packaging materials, refrigeration technology and food preservation techniques which lead to mildew rot is the most serious problem one of the factors . According to the report , so the loss of food in developing countries each year more than 50 % of total production , about 30% of each year ‘s grain, fruits and vegetables in the sales process due to rot and wasted . Plastic food packaging can not guarantee the safety of food , but also can greatly reduce waste and loss of food. Currently in total food consumption in packaging , plastic packaging than the sum of the amount of paper, metal plastic packaging box , glass and other traditional packaging materials , accounting for more than 50 %. Therefore, any standard plastic packaging completely safe to use . For some false rumors in society, we should analyze the scientific attitude and judgment .

Set standards to ensure the safety of the plastic bag material

Plastic packaging , while protecting food from outside contamination , there may introduce some sources . How to prevent the introduction of harmful substances in packaging materials in the production process, is an issue , assistant director of the National Food Safety Risk Assessment Center Wang Zhu days most concern. Wang Zhu day to emphasize that the pvc tray plastic food packaging standards and regulations are plastic food packaging safety of a firewall. In the field of plastic packaging design food packaging materials , the state -level law has strict requirements . Currently, the field of food safety , there are more than 200 standards related to food packaging materials ; addition to the standard , there are some departmental regulations also involves plastic food packaging materials. In these laws and regulations , for the resin used in food packaging , additives and other raw materials and dosage varieties have clear plastic packaging strict rules , as clamshell packaging long as the production process in strict accordance with the relevant standards can guarantee the safety of plastic food packaging .

Recycling for Sustainable Development

With plastic packaging materials widely used in food , plastic food packaging while ensuring food safety , is also facing the challenge how about let themselves achieve sustainable development. Plastics derived from petroleum , are non-renewable resources , and because of stable performance plastics , difficult to degrade themselves , thrown away after the formation of pollution on the environment , so how to dispose of waste plastics become a bottleneck restricting the healthy development of the plastic packaging industry.

PS foam disposable tableware for the lifting of the ban after the “white pollution” Will comeback worry , Li Peisheng clear that the first cause of “white pollution” is not the culprit PS foam disposable tableware itself but discard the bad habits and waste management poor ; secondly , Shanghai implementation of the ” three cents project” prove recycling is the solution to the “white pollution” the most effective way ; again , the introduction of advanced recycling and disposal technologies developed also to solve the ” white pollution” has provided technical support. Li plastic trays Peisheng also revealed that the national authorities are developing new regulations , proposed waste lunch boxes, plastic bags , etc. into compulsory recycling directory . The implementation of these measures are discarded plastic food packaging will reduce environmental pollution and promote low-carbon industry , recycling and sustainable development play an important role .

The thickness uniformity of flexible packaging materials plastic packaging design and packaging costs
?With crude oil prices continued to rise , the cost of polymer packaging materials also rose sharply . Today, however, the intense competition in the market , because if prices of packaging materials and increase the selling price of products in an attempt to increase the cost of all or part of the turn added to the consumers, consumers certainly do not buy . In addition, if the manufacturer trying to reduce costs by reducing packaging performance , which is nothing short of dismantling their signs. Current approaches can effectively solve the rising costs of packaging materials have the following two aspects : first, intensify the development of new polymers, to reduce as much as possible without reducing the amount of packaging material or reduce the cost of packaging performance under the premise ; followed by taking effective means to control the uniformity of the test material thickness , reducing packaging waste resulting rate . The latter relatively easier to implement , thickness measurement using the existing technology can help companies reduce packaging costs.

1 , the importance of uniformity of the film thickness

Thickness uniformity is one of the prerequisites for the protection of materials with specific functions . plastic packaging box In functional barrier material , for example, the barrier layer will directly affect the uniformity of the overall barrier properties of the material . The barrier layer is a barrier layer of the film is the most important , the barrier properties of the barrier film on the one hand the level depends on the clear plastic packaging choice of barrier layer material ( e.g., excellent barrier properties of the current blocking layer materials which are mostly aluminum , aluminum , silicon oxide coated material , PVDC, EVOH , etc. ) ; other depending on the thickness of the barrier layer , the barrier layer is generally thicker the better the barrier properties of the film , when the thickness of the barrier layer reaches a certain level , the barrier properties of the film has become stable , no longer increases with the growth of the barrier layer thickness. Barrier materials are expensive , the thickness of the barrier layer directly affects the overall costs of the barrier film . Application of multi-layer composite film can effectively reduce the packaging cost , wherein the thickness of the barrier layer is only about 10% of the overall thickness of the film , some even only 5m ( or less ) , but difficult to control the thickness of the barrier layer is very large . When the thickness uniformity of the barrier layer is not prone to weak points in the function of the barrier layer , resulting in instability of the entire film barrier properties , poor barrier properties may be part of the packaging material , the resulting product should reach the expiration date , and for part of the film ( especially good transparency film ) barrier layer film thickness changes also affect the overall appearance and vac tray color , reduce the display of goods .

Film thickness uniformity or not will give film printing process and the corresponding increase in the use of difficulty . In commonly used in gravure printing , for example, control the printing of the critical tension to ensure print quality , control and tension the film material , the thickness and uniformity of the thickness have a relationship , caused by poor control of the overlay material can be directly allowed . Further , the film thickness uniformity can also cause poor dislocation phenomenon rewinding the film after printing.

In the production process of multilayer films , the film thickness of any layer can cause uneven unevenness subsequent processing , resulting in the finished film thickness uniformity is worse . Use of this uneven film thickness for packaging , packaging materials when using the mechanical properties of weak points prone , if the packaging , transportation , storage, packaging, sales process, subject to greater external shocks, these weak points prone to cracks , holes and other special save function resulting material is reduced or completely lost .

2 , how to detect the film thickness

Manufacturing and processing of the film , the film thickness detection is one of the most common detection index film , a film thickness detecting the addition into the coating thickness and the thickness detector detects two types . Since the thickness of the film is the total thickness of the resin layers , if the overall difference in the thickness uniformity of the film , wherein the thickness of the resin distribution layers may also differ . Undoubtedly , the detection of the thickness of the coating will be more conducive to effective control film thickness uniformity of the layers , but get the most accurate measurement for each of the multilayer film thickness of the coating on the respective detection equipment need to have a thickness very large investment , and with the growth of the thin film layers increase , to bring greater economic burden. More economical way is expensive coating material portion for detecting the thickness of the coating , while enhancing the overall film thickness uniformity is required to achieve effective control of the role of other layers of material thickness.

Thickness testing equipment can be divided into online thickness measurement equipment and non- line thickness measurement equipment into two categories, these details can be found in two types of devices , ” commonly used method for measuring the thickness of the film ,” a text . If these two types of thickness measurement can be used in conjunction with the device is the best , this is due to line thickness measurement equipment is often used in non-contact measurement, can not be avoided because the material has a compression or a soft bag for the thickness of the material detected is caused by poor surface flatness volatile data , the line thickness measurement device can not provide a contact measurement method ( eg Labthink CHY-C2 uses a mechanical thickness measurement method ) , makes up the line thickness measurement of this a shortage . Although other line thickness measurement can control the film thickness uniformity of the batch , but the finished film is not suitable for sampling must therefore be equipped with a non- line thickness measurement device.

Line thickness measurement device with the fastest speed to get the thickness of the test data , and adjust parameters production line to reduce the thickness fluctuations in material and shorten the production line driving time , but need to be equipped with production lines that match the scanner , which its reuse have certain restrictions, and the price of equipment, operation and maintenance costs to be much more expensive than non -line thickness measurement equipment. Non- line thickness measurement devices are inexpensive , small , easy to use , but the production line thickness parameter adjustment feedback is much slower. Non- many types of online thickness measurement equipment , including mechanical thickness measurement technology applicability of the strongest , it is not selective samples tested free from color products, ingredients change on or reflective surfaces can be used to detect any substance, and plastic trays it in the same thickness measurement will apply some pressure to measure the surface of the sample, which can effectively avoid data due to the compression or samples with poor surface flatness plastic box caused by the volatile situation , very suitable for soft packaging materials thickness detection . Further, since the compressibility characteristics of the film , when the thickness of the detection of various types of thin film with a thickness of the case is often a gap appears , therefore , strict accordance with a predetermined condition is important plastic packaging to select the instrument .

3 , outlook
Increase the thickness uniformity of the test material , can reduce scrap packaging materials , to achieve the purpose of saving costs. Due to the compressibility of the structure of the soft package material itself , making the gauge has been the first choice for all types of machinery and soft packing material thickness detection. However, the mechanical contact type thickness measurement method Measurement limit its clamshell packaging development in the field of line thickness measurement , and therefore , in order to effectively control the thickness uniformity of the material , preferably simultaneously with the line thickness , and non -line testing equipment , which according to the needs of enterprises combination of factors, type of material , thickness uniformity control requirements , the equipment budget to decide.

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 .
