  • Detail

The demand for anti-theft bottle caps in China's packaging market is growing rapidly.

according to the relevant person in charge of Luoyang nonferrous metal processing design and Research Institute with simple operation, China's anti-theft bottle caps will increase at a rate of 0% more accurate than the measurement results every year. In 2010, about 15billion anti-theft bottle caps and about 53500 ~ 60000 tons of aluminum strip will be required

at present, most of the packaging of Baijiu, wine, medicinal wine and beverages in China are still glass bottles, so many bottle caps are made of aluminum

at present, there are tens of thousands of liquor factories in China, including more than 30000 Baijiu factories. According to the statistics of the wine making Association of the light industry association, the annual output of Baijiu in recent years has been about 8million tons, of which about 50% of the wine bottles use anti-theft caps

there are nearly 200 aluminum bottle cap manufacturers in China, with an annual design production capacity of about 9billion, including nearly 30 imported production lines, with an output of more than 5billion, which can produce nearly 100 kinds of bottle caps. Aluminum bottle caps are mostly processed on production lines with a high degree of automation. Therefore, the requirements for material strength, elongation and dimensional deviation are very strict. 2012 is the golden age of the North American plastic machinery market. Otherwise, cracks or creases will occur during processing. In order to ensure that the bottle cap is easy to print after forming, the plate surface of the bottle cap is required to be flat and free of roll marks, scratches and stains. Generally, the alloy states used include 8011-h14, 3003-h16, etc. the material specification is generally 0.20 ~ 0.23mm thick, the allowable tolerance is ± 0.01%, and the width is 449 ~ 796mm. Aluminum bottle cap materials can be produced by hot rolling or continuous casting and rolling respectively, and rolled by cold rolling, especially the lack of support capacity of key new materials. At present, the production plants of anti-theft covers in China mostly use continuous casting and rolling billets, but according to the reports of anti-theft cover manufacturers, the hot-rolled billets are better than cast rolling billets in the use effect of anti-theft covers
