PET beer bottle

It is the most popular beer packaging development. PET bottles have excellent barrier barriers C02, 02, water and aroma properties, high impact resistance, high strength, high compressive strength, high transparency, high cleanliness, good processability, formability, stability, physical and Chemical stability, high temperature resistance, anti-hygroscopicity, anti-scratch resistance, crack resistance, light weight and other concerns, as well as the advantages of recycling, convenient transportation, etc., have been listed and circulated in many countries, with great potential.

The PET beer bottles developed internationally have many varieties and different functions.

The United States has developed a hard carbon film-coated PET beer container. The PET bottle raw material is hydrocarbon. The film contains 60% to 90% of non-crystalline carbon, 10% to 40% of hydrogen, and 200 to 400A of film thickness. , 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 block flavor, excellent chemical stability, acid and alkali resistance, high temperature (300 °C), high transparency, safe to use. Meets FDA safety standards.

In the United States, vacuum plasma enhanced chemical vapor deposition (DPC) technology was developed to coat DLC on the inner surface of PET plastic bottles to achieve a barrier effect between beer and bottles, and improve the barrier properties of PET gas by 5 to 10 times. The PET bottle coated with DLC film has a small odor and has a low adsorption to beer aroma and can be recycled and refilled.

Germany's development of low-cost, cost-effective surface-coated SiO2 PET beer bottles, transparent, good gloss, can be 100% recycled, used for beer filling, shelf life is much longer than 6 months.

The company's Xidaner company developed high-hydrogen non-crystalline carbon-coated PET beer bottles, which have a 10-fold higher oxygen barrier and a 7-fold increase in CO2 resistance. The product has a shelf life of up to one year and can be recycled and used by the FDA. , has been applied in France, Britain, Italy and other countries.

Italy's Sipa company develops disposable PET beer bottle production line, producing from PET pellets to bottle production line. PET bottles have very low oxygen content. Immediate coating and coloring on the exterior of the newly produced bottle, on-line filling and capping, It can prevent the bottle wall from adsorbing oxygen and release it into the product. The bottle can reach super cleanliness, and it can also save the bottle placement site, sterilization and other processes. And the bottle color and coating can be recycled after being removed, and the bottle can be recoated for use. With the quality of the bottled beer, the cost is reduced.

The PET beer bottles introduced by the Swedish company Tetrapa are blown with 500ml Grasrcin's unique technology with a glass-like silica layer on the inside. The inside of the silicon oxide coating is transparent and has excellent barrier properties, which can prolong the beer preservation period.

Australia develops PET bottles with surface-sprayed cycloammonium iced beer. The shelf life of beer under non-refrigerated conditions is 100 to 120 days. PET bottles (90%)/EVOH (10%) are also developed. The shelf life is 25 to 40. Weeks.

The Schmalbach-lubeca, Michigan, company produces PET/N/PET 3-layer beer bottles. The bottle cap is a Japanese PE Groutcork company's attached PE aluminum ring crown cover, with a weight of only 25g, which can maintain beer shelf life of 6 months. PET bottles with PET/EVOH/PET3 layer structure and PET bottles with 3-layer structure using a deoxidizing material as a shielding layer have also been developed. They conform to environmental protection requirements and can be recycled.

Miller USA developed a PET beer bottle with a 5-layer structure (PET/shielding/PET/shielding/PET) with a polyamide shielding layer made of 2 layers of plastic resin, ie, PET and a barrier resin material. Use post-consumer recycled materials. The bottle uses CPT's patented technology, which sterilizes at the pasteurization temperature, will not be deformed, cracked and softened, the physical properties and strength are stable, the beer shelf life is more than 4 months, basically with the glass bottles, metal cans of beer packaging shelves The same period.

Japan's Mitsui Chemicals Co., Ltd. produces industrial-scale hybrid BA-030 copolyesters for 5-layer beer bottles, PET outer layer, BA-030/02 oxygen-removal layer, UV-blocking layer, and PET inner layer. BA-030 is superior to or equal to PEN when combined with PET.
