PET, polyethylene terephthalate, is an environmentally-friendly plastic. Almost all beverage bottles on the market today are molded by PET slicing.
PET packaging was first launched by American PepsiCo in the 1970s. It is cheap, and has good transparency, hermeticity, and compressive strength. In the early 1990s, Japan introduced a heat-resistant PET production facility so that PET bottles can be hot-packed. China's biaxially stretched BOPP bottle produced by the injection-squeezing-pull-blown process has exceeded the PET packaging in transparency, oxygen permeability, low-temperature impact resistance and barrier properties, and is a packaging material with market potential. Beverage packaging containers will have a wide market with the popularity of beverages. The beverage packaging industry in China is still in its infancy. Therefore, it is very promising to research and develop beverage packaging.
The application areas of domestic polyester bottles are mainly concentrated in: carbonated soft drinks, mineral water, edible oils, seasoning foods, pesticides, medicines, daily chemical products, hot-filled beverages, and alcoholic beverages. The various edible oils, mineral water purified water, Coke Sprite tea beverages, and Jianzhuang white wines currently on the market are almost all polyester bottle packaging. The biggest feature is: a ring of kabakaka.
PET bottles are similar in size to glass bottles, but they are lighter and have better gloss than glass bottles, and have caps that can be used repeatedly. Although glass bottle packaging still occupies a dominant position, the single crown cap closure on glass bottles has changed. Now many glass bottles have been improved in terms of bottle caps, and plastic caps have been used to make them easier to use. Some manufacturers also have a plastic cover attached to the bottle neck of the crown cap. In this way, after the crown cover is opened, the plastic cover can be replaced and used repeatedly. At present, China's import of wide-mouth PET bottles is rarely produced, on the one hand because of the small demand; on the other hand, it also constrains the application of PET wide-mouth bottles. However, with the transition of granular and sauce-based foods to high-end products, PET jars are expected to become the most important form of packaging for such condiments.
All beverage brands currently on the market need to be replaced. Glass beer bottles to change the plastic bottle is an international trend, beer bottle replacement has just begun, the dairy beverage market to be open up, Europe's five dairy products have changed the package to a plastic bottle.
At present, there are two listed companies in the industry; Zhuhai Zhongfu has an annual output of 5 billion bottle caps and 4 billion bottles and blanks. In recent years, he has been involved in the R&D and manufacture of beer bottles. Chairman Huang Lefu is ranked 369 in China's richest list. Shanghai Zijiang has an annual output of 1.7 billion bottles and blanks and 5 billion covers. It was founded by Shen Wen in the year of 89 and started as a bottle of Coca-Cola, ranking between 20 and 80 in China's richest list. Both share 30% and 20% of domestic PET bottles respectively.
