Aluminum bottle caps are mostly processed on a production line with a high degree of automation, so there are strict requirements on the strength, elongation and dimensional deviation of the material, otherwise cracks or creases will occur during deep drawing. In order to ensure the convenience of printing after the bottle cap is formed, the aluminum surface of the bottle cap material is required to be flat, without rolling marks, scratches and stains. The aluminum plate of the bottle cap material has 8001-HI4, 3003-H16, etc. The material specifications generally have a thickness of 0.20~43.3mm, an allowable tolerance of ±0.1%, and a width of 449-796mm.
