Compared with plastic bottle caps, aluminum bottle caps have the advantages of simple shape, fine production, no pollution and recyclability, and the production cost is only about half of that of plastic bottle caps.
At present, the aluminum bottle cap materials on the market are mostly made of 8011 aluminum foil. It is required that the plate surface of aluminum bottle cap materials is flat without rolling marks, scratches and stains. The commonly used alloy materials are 8001-h14, 8011-h16, 3003-h16, etc. the material specification is generally 0.20-43.23mm thick, the allowable tolerance is ± 0.1%, and the width is 449-796mm.
The aluminum foil for bottle cap produced by us has tensile strength of 120-140mpa, yield strength of 120-135mpa, ear making rate of 0-2%, thickness difference of + / - 0.005, clean degreasing, and surface dyne value > 56. Advanced equipment, processing technology and strict quality control system are exported to more than 40 countries and regions such as India, Australia and the United States.
