The main aluminum alloys for ropp cap printed aluminium sheet are 1000 series, 3000 series, 5000 series and 8000 series aluminum. The aluminium sheet for ropp caps is mainly used in the fields of caps such as alcohol, beverages and cosmetics. Ropp caps are welcomed in the market for good performance and low cost.

The printed aluminium sheet 1060, 3104, 3105, 5052, 5182, 8011 are widely used in cosmetic caps, wine caps, cans body and cans pulling ring, and the thickness range is 0.15-0.5mm, the wideness range is 200-1500mm, with good deep drawability, good processability, oxidation resistance, smooth surface and no impurities. While when it comes to the ropp cap printed aluminium sheet, the used alloy is 8011 aluminum, the tempers are H16, H18, H24. Aluminium ropp caps have low permeability and even zero permeability. It can effectively prevent the oxidation, and no chemical substances will be produced after long storage time. 8011 aluminum alloy as the main material for ropp caps, in addition to good deep drawing performance, low ear rate, after the cover baking process, it also has a certain strength. 8011 aluminum closure sheet for ropp caps material can be mechanized with large-scale, pollution-free, recyclable and other advantages, widely used in life.
