Development of PET beer bottles in various countries of the world

Pet is the most popular beer packaging development, it has excellent barrier barriers co2, o2, water and aromatic properties, high impact resistance, high strength, high compressive strength, high transparency, high cleanliness, good processability , Moldability, stability, physical and chemical stability, high temperature resistance, anti-hygroscopicity, anti-surface scratch resistance, crack resistance, light weight, etc., as well as the advantages of recycling, transportation convenience, etc. Many countries are listed and have great potential.

The pet beer bottles developed internationally have many varieties and functions. The United States has developed a hard carbon film coating pet beer container, pet bottle raw material for hydrocarbon, 60% -90% of the film composition of amorphous carbon, 10% to 40% of hydrogen, film thickness 200-400a , Its barrier ability is improved by more than 10 times, material elasticity is flexible, and the film will not be damaged when stretched. Hard carbon film can absorb micro odor and fragrance, chemical stability, acid and alkali resistance, high temperature (300 °C), transparent empty high, safe use, in line with the United States fda safety standards.

The United States developed vacuum plasma enhanced chemical vapor deposition (DPC) technology to coat diamond-like carbon (dlc) on the inner surface of pet plastic bottles, which has a barrier effect between beer and bottles, and improved pet gas discardability by 5-10 times. The PET bottle coated with dlc film has a small odor and has a low absorption of beer aroma and can be recycled and refilled with beer.

Germany's development of low-cost pet coated sio2 pet beer bottles, transparent, good gloss, can be 100% recycled, used for beer filling, shelf life is far more than 6 months.

Sidel France developed high-hydrogen non-crystalline carbon-coated pet beer bottles with 10 times higher oxygen barrier and 7 times higher co2 resistance. The product has a shelf life of up to one year and can be recycled and used by fda. , has been applied in France, Britain, Italy and other countries.

Italy's Sipa company develops a one-time pet beer bottle production line, from PET pellets to the bottle production line. PET bottles have very low oxygen content. They are immediately coated and colored outside the newly produced bottle. Online filling and capping can Prevents the bottle wall from being oxidized and released into the product. The bottle is super clean, and it also saves the bottle's disposal site and sterilization process. Moreover, the color and coating of the bottle can be recycled after being removed, the clean bottle can be used for recoating, and the bottled beer can be used to ensure the quality and reduce the cost.

The pet beer bottle introduced by Sweden is made of a glass coated silicon oxide film with a thin inner layer of 50 (hnlgrasrcin unique technology blow molding. The inside of the silicon oxide coating is transparent, and the barrier property is very excellent, which can prolong the beer preservation period.

Australia develops an ice beer PET bottle with surface-sprayed cycloamine, and the shelf life of beer under non-refrigerated conditions is 100 to 120 days, and pet (90%)/evoh (100%) beer bottles are also developed with a shelf life of 25-40. Weeks.

The American Schmalbachlubeca company produces pet/n/pet 3 layer beer bottles. The bottle caps are Japan's growncork company's aluminum crown caps with PK pull rings. The cover weight is only 25g, and it can maintain beer shelf life of 6 months. It also developed pet/evoh/pet3 layer beer bottles and pet beer bottles with a 3-layer structure using a deoxidizing material as a shielding layer, which meets environmental requirements and can be recycled.

Miller, USA, developed a pet beer bottle with a 5-layer structure (pet/shield/pet/shield/pet) of a polyamide shielding layer, made of 2 layers of plastic resin, ie, PET and a barrier resin material, and the core PET. Made of a barrier resin material, the core PET can be recycled after use. The bottle adopts cpt patented technology. The bottle is pasteurized and will not be deformed, cracked and softened. The physical properties and strength are stable. The beer shelf life exceeds 4 months, basically the same as the shelf life of glass bottles and metal cans. .

Japan's Mitsui Chemicals Co., Ltd. produces a mixed-type ba-030 copolyester on an industrial scale, used in beer bottles with a 5-layer structure, pet outer layer/ba-030/02 oxygen-removal layer/UV-blocking layer/pet inner layer. The performance of ba-030 combined with pet is better than or equal to pen.
