At present, most of the packaging of liquor, wine, medicinal wine and beverages in my country is still mainly glass bottles, so the bottle caps are made of aluminum. At present, there are tens of thousands of wine production factories in my country, among which nearly 30 liquor bottle cap production lines can produce nearly 100 kinds of bottle caps, with an output of more than 5 billion. According to relevant experts, my country's defense thief bottle caps will grow at an annual rate of 10%. It is estimated that in 2010, about 15 billion anti-theft bottle caps will be needed, and 53.5-60,000 tons of aluminum plates will be consumed.
Since the mid-1990s, the PET bottled beverages produced by Coca-Cola Company have replaced aluminum caps with plastic anti-theft caps, thus pushing plastic anti-theft caps to the forefront of beverage packaging. Since then, domestic powerful packaging companies and beverage manufacturers have introduced foreign equipment and started mass production and application of plastic anti-theft caps. Nowadays, plastic anti-theft bottle caps that are both thin and easy to open are used for beverage packaging not only to facilitate 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 companies are adopting 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), Nestal (Nestal), Engel (Engel) and other world-renowned cap 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 technology has also kicked off. Technical innovation is undoubtedly the driving force for the rapid development of plastic anti-theft covers.
