There are mainly three aluminum alloy sheets for closures: 5052, 3105 and 8011. 5052 aluminum strip has excellent deep drawing performance and paint adhesion, ensuring he highest printing and deep stamping quality. It is used as can lid material. Haomei Aluminum can offer color coated or plain aluminum strip.
The surface of 5052 aluminum strip is not allowed to have black spots, corrosion marks, straightening roller marks, oil stains, punctures, scratches, etc. The flatness of the aluminum strip is greater than 10 (or the wave height is less than or equal to 3 mm).
8011 aluminum sheet is often used for PP, ROPP, screw caps of wine bottle, medicinal bottle and injection bottle. Haomei Aluminum can provide different surface processing solutions: ordinary finish-rolled aluminum sheet, DOS oil lubrication treatment, chrome treatment, couble-sided varnish/transparent paint and different colors of two sides.
3105 aluminum alloy plate for closure belongs to the Al-Mg alloy. It has good rust resistance and good deep-drawing effect. The strength, elongation and processing performance of the material can meet the requirements of the automatic production process of high-strength bottle caps, and there will be no creases during processing.
The main thickness of 3105 bottle cap material is 0.15-0.3mm, and the tempers are O, H12, H14, H16, etc. On the basis of ordinary aluminum plate, Haomei Aluminum can chromate the 3105 aluminum plate, do DOS oiling or print various colors.
