Aluminum bottle cap materials are more and more used in people’s life, replacing the original tinplate and stainless steel. The aluminum anti-theft bottle cap is made of high-quality special aluminum alloy materials. It is mainly used for the packaging of wine, beverage (including steam and without steam) and medical and health products, and can meet the special requirements of high-temperature cooking and sterilization.
Aluminum bottle caps are mostly processed in production lines with a high degree of automation, so the requirements for material strength, elongation and dimensional deviation are very strict, otherwise they will break or crease during processing. In order to ensure the convenience of printing after the bottle cap is formed, the material plate surface of the bottle cap is required to be flat and free of rolling marks, scratches and stains. Generally, the alloy state is 8011-h14, 1060, etc., and the material specification is generally 0.17mm-0.5mm thick and 449mm-796mm wide.
The 1060 alloy is a kind of cover making method combining aluminum and plastic. Because aluminum plastic part will contact the liquid in the bottle, so most of them are applied to the cosmetics industry, some of them are applied to the pharmaceutical industry, and the 8011 alloy is generally made by direct stamping forming method, and the 8011 alloy has better performance, the use of Baijiu and red wine covers is very high. The stamping depth is large, which can reach 60-80mm, and the oxidation effect is good. The proportion with tinplate can reach 1 / 10. It has the advantages of high recycling rate and environmental protection, so it is accepted by more manufacturers and customers.
