Development status of glass bottles and caps in China
At present, most of the packaging of liquor, wine, medicinal Baijiu and beverage is mainly made of glass bottles, so the bottle cap is made of aluminum. At present, there are several tens of thousands of alcoholic drinks factories in China, of which nearly 30 Baijiu production line can produce nearly 100 kinds of bottle caps, and the output is about 5000000000. According to relevant experts, China's anti-theft bottle caps will grow at a rate of 10% per year. It is estimated that about 15 billion anti-theft bottle caps will be needed in 2010, and about 53500 ~ 60000 tons of aluminum plates will be consumed.
Since the mid-1990s, PET bottled drinks produced by Coca Cola company have used plastic anti-theft cover instead of aluminum cover, which has pushed the plastic anti-theft cover to the front desk of beverage packaging. Since then, powerful domestic packaging enterprises and beverage manufacturers have introduced foreign equipment and started the large-scale production and application of plastic anti-theft covers. Nowadays, the thin and easy to open plastic anti-theft bottle cap is used for beverage packaging, which not only facilitates consumers, but also speeds up the development of the beverage industry. At present, due to the fierce competition in the domestic beverage industry, many well-known enterprises are using new production processes and equipment, so that China's capping machinery and plastic capping production technology have reached the world advanced level. For example, sacml, Alcoa, husky, Demag, nestal, Engel and other world-famous capping machines have entered China. At the same time, in the field of plastic bottle cap production, the dispute between injection molding and compression molding technology has also opened a big curtain. Technological innovation is undoubtedly the driving force for the rapid development of plastic anti-theft covers.
