At present, most of the packaging of Chinese liquor, wine, medicinal wine and beverages is still dominated by glass bottles, so the bottle caps are made of aluminum. At present, there are tens of thousands of various wine production plants in China, including nearly 30 liquor bottle cap production lines, which can produce nearly 100 kinds of bottle caps, with an output of more than 5 billion.
Since the mid-1990s, the PET bottled beverages produced by Coca-Cola Company replaced the aluminum cover with plastic anti-theft caps, which pushed the plastic anti-theft cap to the front of beverage packaging. Since then, powerful domestic packaging companies and beverage manufacturers have introduced foreign equipment and started large-scale production and application of plastic anti-theft covers. Today, the thin and easy-to-open plastic anti-theft bottle caps are used in beverage packaging not only for the convenience of consumers, but also to accelerate the development of the beverage industry. At present, due to the fierce competition in the domestic beverage industry, many well-known enterprises have adopted the production technology and equipment, so that my country's cap-making machinery and plastic cap production technology have reached the world's advanced level. Such as Sacmi (SACMl), Alcoa (Alcoa) Husky: (Husky), Demag (Demag), NETZZ (Nestal), Engel (Engel) and other world-renowned cover-making machinery have entered my country. At the same time, in the field of plastic bottle cap production, the battle between injection molding and compression molding has also kicked off. Technological innovation is undoubtedly the driving force for the rapid development of plastic anti-theft covers.
