Domestic and foreign alcohol packaging new materials new containers

Good packaging can improve the taste of wine, as well as the important function of maintaining and improving the quality of wine. With the rapid development of the wine industry and the expansion of consumer groups, international new materials and containers for wine packaging have been developed and applied one after another, winning the market with their respective functions and advantages.

PET beer bottle

PET is the most popular beer packaging development, it has excellent barrier barrier CO2, O2, water and aroma 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-coated PET beer container. The raw material of PET bottle is hydrocarbon. The film contains 60%-90% of amorphous carbon, 10%-40% of hydrogen, 200-400A 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, chemical stability, acid and alkali resistant, high temperature (300 °C), transparent empty high, safe to 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 to achieve a barrier layer effect between beer and bottles, and to increase PET gas barrier properties by 5-10 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 develops low-cost, cost-effective surface-coated SiO2 PET beer bottles that are transparent and glossy and can be recycled 100% for beer filling. The shelf life is much longer than 6 months.

The Sidel company of France develops a PET bottle with high hydrogenation amorphous carbon coating. Its oxygen barrier property is increased by 10 times, CO2 resistance is increased by 7 times, and the product shelf life is up to one year. It 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, from PET pellets to bottle production line production, PET bottle oxygen content is very low, coating and coloring immediately 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 50mm glass-like silicon oxide film on the inner side (the unique technology of hnlGrasrcin is used for 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 PET bottles with surface-sprayed cycloammonium ice beer. The shelf life of beer under non-refrigerated conditions is 100 to 120 days. PET bottles (90%)/EVOH (100%) are also developed. The shelf life is 25-40. Weeks.

The Schmalbachlubeca company in the United States produces PET/N/PET 3-layer beer bottles. The bottle cap is a Japanese company Growncork's PK pull ring aluminum crown cover, which only has a weight of 25g, and can maintain beer shelf life of 6 months. PET bottles with PET/EVOH/PET three-layer structure and three-layer PET bottles with oxygen-removing material as the shielding layer have also been developed to meet environmental protection requirements and can be recycled.

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

Japan 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/PET inner layer. The performance of BA-030 combined with PET is better than or equal to PEN.

PEN new polyester beer bottle

The development of PEN new beer bottles has attracted the attention of the international packaging industry. PEN is polyethylene naphthalate. The difference from PET is that the naphthalene ring is used instead of the benzene ring of PET, and the monomer of the polymerization raw material is NEC instead of terephthalic acid. PEN and PET have similar molecular structure, but they have better barrier properties, UV resistance, heat resistance, and high temperature resistance than PET (non-crystalline PEN thermal transition temperature is up to 100°C, while PET temperature resistance is only 20°C). PEN is not only used for beer packaging, but also for packaging of other wines and beverages. The market prospect is very wide.

Other new materials New containers

PET nanoplastics (NPET) beer bottles were developed by the Chinese Academy of Sciences and used PET polymer intercalation and intercalation technology. The organic montmorillonite and PET monomers were added together into a polymerizer. NPET has a stronger barrier than ordinary PET. - 5 months storage, the same taste as fresh beer.

The plastic bottle that can be sterilized by high temperature is manufactured by Kortec's multi-layer co-injection process. The beer bottle can withstand high temperatures of 67°C. The barrier layer is excellent in sealability and can withstand beer for 6 months.

Eco-friendly beer bottle produced by Asahi Co., Japan, made of shrinkable Eastar co-polyester film adhesive tape, which can block light, ensure beer quality, seal caps, transport safety, cover will not be opened, bottle body is kept clean, bottle body is prevented Cracked debris and other characteristics.

Plastic Beer Bottles The Netherlands uses a polyethylene terephthalate outer layer that has been specially treated to make beer beer that will not oxidize within six months.

The colored new type beer bottle was developed in Japan and coated with organic pigments on a colorless bottle body. When it is reused, the colored component is decomposed into a colorless state at a high temperature of 1400°C to 1500°C, and it can be recycled and used for wine.

Breathable fresh beer barrels Qingdao Guanghua Brewing Container Co., Ltd. has developed a Neil E-type anaerobic beer barrel, which is a new type of beer packaging container. It uses a unique combination of an automatic inflation pressure storage structure and a built-in miniature cylinder to ensure The anaerobic operation in the whole process of wine and wine storage guarantees the taste of bottled beer. The inner wall of the product is a smooth stainless steel liner that is easy to clean. MICRO MATIC's wines increase the reliability of the barrel, PU foam insulation layer with uniform thickness has good insulation, the wine system has a strong defoaming function, wine barrels can not put air into the barrel due to anaerobic wine. Beer oxidation and secondary pollution.

Canned beer can be packaged with good quality, high grade, easy to carry, easy to transport and drink, not easy to be counterfeited, superior sealing performance, clean, hygienic, and maintain a high degree of beer inherent flavor, suitable for high-end beer packaging, high prices For people with higher spending power. Cans are not only used for beer packaging, Australia and other countries have developed cans of wine packaging. Cans can completely isolate the air and prevent the oxidation of wine. It is more convenient, environmentally friendly and safe than glass bottles.
