At present, most of the packaging of liquor, wine, medicinal wine and beverages in my country 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 factories in my country, 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. According to relevant experts, my country's anti-theft bottle caps will grow at an annual rate of 10%. It is estimated that about 15 billion anti-theft bottle caps will be needed in 2010, and about 53,500 to 60,000 tons of aluminum plates will be consumed.
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, the production technology and equipment adopted by many well-known enterprises have made our country's cap-making machinery and plastic cap production technology reach the world's advanced level. 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.
