At present, most of the packaging of liquor, wine, medicinal wine and beverages in my country is still dominated by glass bottles, so the caps are made of aluminum. At present, there are tens of thousands of various alcohol production plants in my country, among which there are nearly 30 liquor bottle cap production lines, which can produce nearly 100 kinds of various types of bottle caps, and the output is more than 5 billion. According to relevant experts, the number of anti-theft caps will increase at a rate of 10% per year. It is estimated that about 15 billion anti-theft caps will be needed in 2010, and about 535,000 to 60,000 tons of aluminum plates will be consumed.
Since the mid-1990s, PET bottled beverages produced by Coca-Cola Company have used plastic anti-theft caps instead of aluminum caps, thus pushing the plastic anti-theft caps 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. Nowadays, the thin and easy-to-open plastic anti-theft bottle caps used in beverage packaging not only facilitate consumers, but also accelerate the development of the beverage industry. At present, due to the fierce competition in the domestic beverage industry, many well-known enterprises are using the production process and equipment, so that my country's cap making machinery and plastic cap production technology have reached the world's advanced level. Such as SACMl, Alcoa Husky, Husky, Demag, Nestal, 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 has also begun. Technical innovation is undoubtedly the driving force for the rapid development of plastic anti-theft covers.
