Aluminum Sheet in Coil for Pilfer Proof Caps
Aluminum sheet in coil for Pilfer Proof Caps are generally used 8011-H14, 1060, 3004, 3105 and other aluminum alloys, the specifications are generally 0.20-0.23mm thickness, allowable tolerance ± 0.01%, width of 449-796mm. Aluminum Pilfer proof caps are generally processed in the production line with a higher degree of automation. Therefore, the strength, elongation and dimensional deviation of the aluminum sheet coil material are required to be very strict, otherwise it will produce rupture or crease in the deep drawing process. In order to ensure that the bottle cap is easy to print after molding, it is required that the plate surface of the pp cap aluminum coil is flat and free of roll marks, scratches and stains. Aluminum Pilfer Proof caps are made of high-quality aluminum alloy material, which can overcome the shortcomings of plastic bottle caps. Aluminum Pilfer Proof caps structure is simple, adaptable, sealing effect is good, not only can print colo...
