Development trend and Prospect of plastic packagin

Prospects for the development trend of beer plastic packaging

beer packaging is the carrier of beer sales. It determines the appearance quality and shelf image of beer, is directly related to the market sales performance of beer, and is also an important aesthetic expression level of beer culture. Beer has very strict requirements for packaging containers, especially for the oxidation resistance and barrier performance of packaging containers. Oxidation resistance and ensuring the content of carbon dioxide are important factors that directly affect the quality of beer

in recent years, due to the continuous emergence of various new technologies and materials, beer packaging has broken the long-standing situation of glass bottles dominating the world, and plastic packaging is entering the field of beer packaging with a rapid trend. Plastic packaging has brought great changes to the material, process and technology of beer packaging

plastic packaging in the beer industry

plastic is widely used in modern industry, but in the past, the problem of ensuring the quality of bottled beer (not only to avoid oxygen entering the bottle, but also to prevent carbon dioxide from escaping from the bottle) has not been solved, so it has been excluded from the field of beer packaging

with the continuous application of various new technologies and the continuous emergence of new materials, plastics have overcome the performance obstacles of its application in beer packaging. PC, pet, pen, the mixture of pet and pen, and other new plastics such as PETG have been widely used in the field of beer packaging

pcpc is formed by the polymerization of diphenyl ester and monophenol A. its advantages are good heat resistance (high temperature above 120 ℃) and high mechanical strength. PC was used in the field of beer packaging earlier, but its price is expensive and its gas barrier performance is poor, so it has gradually withdrawn from the field of beer packaging. It is reported that now there are improved PCs that have been reintroduced to the market and used in the fields of beer and beverage packaging, such as the existence of various friction forces, which will affect the compressive capacity of the test pieces and even the damage situation. Therefore, 1 it is necessary to regularly check the temperature and vibration of electromechanical devices and internal wires

pen is scientifically called polyethylene naphthalate, and its precursor product is DNC (dimethylnaphthalene). Pen has good heat resistance and gas barrier, can resist ultraviolet rays, and can also withstand pasteurization and high-temperature soaking temperature. Its service life can exceed 6 months, and its weight is light. It is a good beer packaging container. Mr. Cerard Denis, project manager of the research and Development Department of SIPA company in Italy, said at the American beverage packaging seminar that beer bottles made with pen have shown little difference from glass bottles in Italy and Asia. However, due to the high cost of its raw materials ethylene glycol and dimethyl-2.6-naphthalene-dicarboxylic acid, the promotion and use of pen is limited (only applied to some higher grade beer)

due to the price barrier of pen, PET materials have appeared in the market. Pet is polyethylene terephthalate. Because it is not resistant to high temperature, it was first developed for cold sterilized beer. Because cold sterilization uses membrane filtration technology, it does not undergo pasteurization or high-temperature instantaneous sterilization. Pet can not well block the penetration of gas, so not only the content of carbon dioxide is insufficient, but also it is easy to oxidize and deteriorate beer. The shelf life of beer is relatively short, so its application is greatly limited

in view of the respective shortcomings of pen and pet, researchers have introduced pen and PET blend materials, that is, 15% pen and 85% pet are mixed, and then processed by special processes, so that their performance indicators are greatly improved, almost reaching the level of glassware and metalware, and their packaging performance price ratio is also better than glass bottles

the Department of recording downtime, damaged parts and fracture conditions of France Sidel packaging company said that this was a technical problem they solved after more than two years of development and research. The key to this technology is to obtain amorphous carbon from high-temperature plasma and add a very small amount of amorphous carbon into the materials used to manufacture plastic containers. According to the data provided by Olivieri, the new process can improve the oxygen resistance of the bottle by 29 times and the barrier performance by 6 times. After more than six months of packaging experiments on different beers, it has been proved that its performance indicators are almost the same as those of glass and metal packaging, but the cost is much lower. In the European market, its price is only 78% of glass bottles and 65% of metal cans

PETG Eastman Chemical Company of the United States is one step ahead in beer plastic packaging. Its new environmentally friendly plastic packaging beer bottle produced by Asahi company has also been put on the market. This wine bottle is sealed and packaged by a material called eastal copolyester film adhesive tape, that is, PETG (polyester material modified by glycol). Its shape is silver ink, and the black hole ribbon pull ring cover is added to the neck, which can block light, isolate air, ensure the quality of beer, and has the explosion-proof function of preventing debris from splashing when the bottle body is broken, with superior shrinkage performance. Since Asahi adopted this packaging material, the sales of super dry and dunk beer have increased significantly

prospect of plastic beer packaging

plastic beer packaging, with its flexible shape and volume, first turns on the advantages of computer variability and colorful colors, so that the majority of manufacturers and consumers are convinced

for beer packaging, plastic has obvious advantages over glass and metal

first, it can reduce the loss of various beneficial ingredients in beer and prolong the fresh-keeping period of beer

second, plastic packaging is light and safe, not easy to break and explode, and the cost of filling, storage and transportation is significantly lower than that of glass and metal packaging

third, plastic packaging has a high recycling rate, which greatly saves marketing costs, and is conducive to environmental protection and comprehensive utilization of resources

with the more and more extensive application of plastics in the field of beer packaging, today, people are trying to stimulate the market with new shapes and packaging specifications, so that both beer manufacturers and dealers can increase profits. Because except for single-layer plastic bottles, any treatment method will increase the cost and reduce the competitiveness of the packaging. Mr. craigrenton, director of new product sales department of constar international branch of crouncork seal company, pointed out that you must weigh the advantages and disadvantages between using plastic as light as possible and post molding treatment. Renton also pointed out that the post-processing technology of molding to increase crystallinity still needs to be improved. Now, Denis of SIPA company has shown people 33 centiliter (about 12 ounces) brown beer bottles at the American beverage packaging conference, indicating the bright future of plastic packaged beer
