Beverage packaging industry also appears diversification trend , breaking the monopoly over a single glass container market structure , metal, plastic , paper materials have been used in the beverage packaging, metal cans , PET bottles , PP bottles, Tetra Pak , Combibloc , roof bag , black and white film packaging stage.

According to statistics, China ‘s annual production of beverages substantially increasing trend year by year , to maintain double-digit percentage growth rate of about 10 % to 20% , with an average annual production is close to 30 million tons , is the pace of development of the food industry ‘s most one industry fast. At present , the domestic beverage market, popular mainly with fruit , fruit juices fiber , low sugar or no sugar tea drinks , and bottled water and other products, and is expected in 2007 will be the fastest growing beverage products are low sugar or sugar -free drinks , each flavors of tea and fruits and vegetables , flowers, health drinks category . With the breakdown products gradually refined and trends for different beverage beverage market consumer groups will behave more plastic packaging colorful.

Status beverage packaging market

With the emergence of a wide range of beverage types , beverage packaging industry has developed rapidly , after breaking the monopoly of the pattern of a single glass container market , metal containers , plastic containers, paper containers have appeared , showing the diversification of beverage packaging trend. Carbonated drinks and pure water , mineral water market after years of accumulation , the market has clamshell packaging been quite stable , Coca-Cola beverage cans classic image of the packaging can not be easily shaken , and mineral water drinks like to occupy a certain share of the market , only in PET bottles on the type of design and capacity to do changes in recent years for families and food consumption 2L package quite markets.

First, the glass

Glass is a long history of packaging materials , glass is also China’s traditional beverage containers. In the case of a variety of packaging materials into the market of glass containers in the beverage packaging still occupy an important position , because it can not be replaced with other packaging materials packaging features, but began to significantly reduce the amount . The main features of glass packaging containers are: non-toxic, odorless, transparent , beautiful, good plastic packaging design barrier , airtight , abundant raw materials, low prices, and you can use multiple turnover . And with heat , pressure , resistance to cleaning the advantages of both high-temperature sterilization , but also cold storage . It is precisely because it has many advantages , it became tea, jujube juice for many beverage containers require a higher material of choice. But glass containers also have some disadvantages : mainly self-important, easy to damage , high transport costs, poor printing and other secondary processing performance , resulting in a substantial reduction in usage started , now on the shelves of supermarkets has basically do not see the glass beverage containers , and in schools, small shops , canteens, hotels, and other small power consumption is not high places, to see the cheap glass bottles of carbonated drinks , milk and herbal tea plantations.

Second, the metal can

Metal cans of beverage packaging two cans and three cans. Two cans of aluminum sheet metal mainly used for carbonated beverage packaging ; while three cans with tinplate ( tin ) mainly used for free carbonated beverage packaging.

Metal cans as beverage packaging has the following advantages : First, with excellent barrier properties. Not only can the gas barrier , light plastic trays barrier may also , this feature allows the beverage has a longer shelf life. Second, with excellent mechanical properties, mainly in the high temperature, high humidity , pressure , resistance to pests and erosion resistance of harmful substances. Third, unbreakable, easy to carry, to adapt to the fast-paced life of modern society . Fourth, surface decoration , and can stimulate consumption and promote sales. Fifth, you can use recycled recycling . But the metal packaging containers also has some disadvantages , mainly in the chemical stability , alkali poor , poor quality of the paint or technology, however , will make the drink taste. China ‘s current annual consumption of aluminum cans 60 to 7 billion , the need to import large quantities of raw materials , and expensive, plus the pollution of the environment and other factors , the state has not approved a new production line of aluminum cans .

Third, plastic packaging

Beverage plastic packaging clear plastic packaging industry has attractive opportunities in 2002 , beverage production reached 20.24 million tons , increasing demand for soft drinks, fruit juices , vegetables, beverages required plastic containers. Today’s beverage market , PET occupy a major position in the tea, carbonated drinks , fruit juice, bottled water containers applications prospects. If people at first sight of Watson’s “Ring treasure ” bottle , slim Huiyuan “He + She – ” plastic bottles, pleasant Yanjing ” stuff ” tapered bottles , PET beverage packaging allows modeling becomes mix.

The past two years , new packaging Chinese beverage market up more gradually , at present, the type of plastic used in beverage packaging main categories:

1, PE ( polyethylene ) :

PE is the world’s largest output of synthetic resin , is the largest consumption of plastic packaging materials . Products are divided into low-density polyethylene , medium-density and high-density three. Wherein the high density polyethylene (HDPE) having a high crystallinity due to their hardness, tightness , mechanical strength, chemical resistance are better, so that the blow molding is made ??of a large number of bottles and other hollow containers . Use PE and good sealing performance , container production of composite materials , can be dressed with lemon juice , fruit juice and other beverages .

2, PVC ( polyvinyl chloride ) :

PVC can be divided into hard goods, soft goods and pasty products categories. Produced by injection stretch blow seamless line of PVC bottles , bottle wall Bohou uniform, can be dressed carbonated beverage such as cola , soft drinks , etc. ; using extrusion blow molding production of PVC bottles containing juice and apply only to mineral water .

3, PP ( polypropylene ) :

Development of transparent polypropylene bottles at home and abroad in recent years, a hot plastic packaging . With transparent modifier – the successful development of a nucleating agent , adding 0.1% to 0.4 % sorbitol shrink xylene ( benzaldehyde ) nucleating agent in the PP in general , produced by the high transparency PP bottles can be widely used heat sterilization needs that require high temperatures , such as fruit juice concentrates filling beverage packaging , and its affordable , pressure resistance to temperature , is PS, ABS, PET, PE bottles freshman opponent.

4 , the polyester (PET or PETP):

Biaxially stretching blow molding using the produced PET bottles , having good transparency , surface gloss, glassy appearance and is most suitable in place of glass bottles . In recent vac tray years , the rapid development of production of PET bottles are widely used in various tea drinks , fruit juices and other drinks hot filling needs , such as Pepsi 600ml, 1.25L, 2L and 2.5L PET bottles , different volumes for individuals, families different needs , by the majority of consumers.

From a market share of each of the world’s great powers in terms drinks , PET bottles share in excess of 70%. The results of a survey showed that by 2007, the European food and beverage plastic packaging market sales will be $ 4.91 billion in 2000 , increased to packaging design $ 7.15 billion , an average annual growth rate of 5.5%. At present, China is in a stage of rapid development but also PET beverage packaging , the demand for PET bottles to double-digit growth every year. Application proportion of domestic carbonated plastic box beverage packaging PET bottles accounted for 57.4 %, showing that PET bottle packaging has occupied a major share of the domestic beverage packaging market. Consumers widely considered PET bottles have a ” large capacity , transparent, intuitive and strong , lightweight and easy to open , can be refrigerated , portable, rugged, recyclable ” and other features , its development has provided a broad market prospect.

Fourth, paper containers

Paper containers used in beverage packaging, the paper mainly refers to Tetra Pak composite PE film or aluminum foil made ??of Combibloc packaging containers and other paper-plastic composite , the shape of the roof package , sterile square bricks , low cost, lightweight, pollution-free, recyclable and other characteristics, is environmentally friendly packaging. Mainly used for short-term preservation of milk, yogurt and long-term preservation of dairy drinks, tea drinks and fruit juice drinks packaging. However, the degree of pressure resistance and sealing barrier paper-plastic containers are not as plastic packaging box glass bottles, metal cans and plastic containers , not pasteurized , so preformed cartons in the preservation process , due to oxidation of PE film and reduce its heat sealing performance, or because of the crease below the fiber sclerosis and other reasons to become uneven , causing problems filling machine feeding difficulties occur.

April 2006 , the Coca-Cola company selected SIG Combibloc 1.5L polygonal large aseptic carton packaging, the use of four large flat exterior carton full of product features for its popular brand of Nestle NESTEA Iced tea made ??a re- positioning , let stand out on the shelf , to win the favor of consumers .
