A basic introduction to Aluminium Closure

Aluminum caps are mostly processed in highly automated production lines, so the strength, elongation and dimensional deviation of the material are very strict, otherwise cracks or creases will occur during processing. In order to ensure that the cap is easy to print after forming, the cap material is required to have a flat surface and no roll marks, scratches and stains, and the alloy states generally used are 8011-H14, 3003-H16, etc., and the thickness of the material is 0.20mm~0.23mm, and the width is 449mm~796mm. The production of aluminum cap materials can be made by hot rolling blank or continuous casting and rolling blank, and cold rolling. At present, the production plants of China's anti-theft cover materials mostly use continuous casting and rolling blanks, which are better than casting and rolling blanks.

Oriental Network September 17 news: industry insiders, China's anti-theft bottle caps will grow at an annual rate of 10%, in 2010 about 15 billion anti-theft bottle caps, aluminum strip 53,500 ~ 60,000 tons, the development is very rapid. The demand for aluminium closures is growing rapidly. At present, most of the packaging of liquor, wine, medicinal liquor and beverages in China is still dominated by broken glass bottles, and many bottle caps are made of aluminum. At present, there are tens of thousands of various liquor production plants in China.
