schmalbachlubeca of the United States produces PET/N/pet3 beer bottles. The bottle cap is an aluminum crown cap with PK pull ring from growncork of Japan. The cap weight is only 25g, which can maintain the shelf life of beer for 6 months. PET/EVOH/PET beer bottles with three-layer structure and PET beer bottles with three-layer structure with deoxygenation material as shielding layer are also developed, which meet the requirements of environmental protection and can be recycled

American Miller Company has developed a PET beer bottle with polyamide shielding layer 5-layer structure (PET/shielding layer/PET/shielding layer/PET), which is made of two layers of plastic resin, namely pet and shielding resin material, and the core layer pet and shielding resin material. The core layer pet can be recycled after consumption. CPT patented technology is used for bottle making. This bottle adopts pasteurization and will not deform, crack and soften. The new polyurethane waterproof coating has modified the technical requirements of rationality and stable strength. The shelf life of beer is more than 4 months, which is basically the same as that of glass bottles and metal cans

Mitsui chemical company of Japan produces mixed ba-030 copolyester on an industrial scale, which is used in beer bottles with 5-layer structure, pet outer layer/ba-030/02 deoxygenation layer/UV barrier layer/Pet inner layer. When ba-030 is compounded with pet, its performance is better than or equal to pen

The development of pen new polyester beer bottle has attracted the attention of the international packaging industry. Pen is polyethylene naphthalate, which is different from pet in that naphthalene ring is used to replace the benzene ring of pet and NEC is used to replace terephthalic acid in the monomer acid of polymerization. Pen is similar to pet in molecular structure, but it has better barrier property, UV resistance linearity, heat resistance and high temperature resistance than PET (the thermal change temperature of amorphous pen is as high as 100 ℃, while the temperature resistance of pet is only 20 ℃). Pen is not only used in beer packaging, but also in the packaging of other wines and beverages, and its market prospect is very wide
