Currently, aluminum bottle caps on the market generally use 8011-H14, 1060, 1070, 1235, 3004, 3105 and other Aluminum foil cap sheet. The material specifications generally have a thickness of 0.20-0.23mm, an allowable tolerance of ±0.01%, and a width of 449-796mm. , A-level brushing, low ear cutting rate. Widely used in wine bottle caps, cosmetic bottle caps, milk powder caps, medical caps, beverage caps, yogurt caps, ROPP caps, aluminum easy-open caps, etc.

The aluminum cap closure foil also has good air barrier properties, anti-oxidation, waterproof, moisture-proof and other characteristics. It has strong mechanical properties, high blast resistance, strong puncture and tear resistance, high temperature resistance, low temperature resistance, oil resistance, and good fragrance retention properties. , non-toxic and tasteless, in line with food hygiene standards.

8011 aluminum foil mainly adds elements such as Fe and Si. It has excellent moisture-proof performance, light-shielding performance, high blocking ability, stable physical properties, easy stamping, and high strength. The surface texture is fine and there are no black lines, and the tensile strength is greater than 165.

1060/1070 pure aluminum foil has the characteristics of high plasticity, corrosion resistance, electrical conductivity and thermal conductivity.

1235 aluminum foil is often used to stamp aluminum bottle caps. Aluminum bottle caps combine aesthetics, sealing properties and good printing effects. They are currently a commonly used bottle cap form in the beverage, wine, cosmetics, medicine and health care industries.

3004/3105 aluminum closure sheet belongs to the 3 series aluminum-manganese alloy. It has good anti-rust properties and good deep drawing effect. The strength, elongation and processing performance of the material meet the requirements of the automated bottle cap production process with high intensity. It does not need to be processed during processing. There may be creases or cracks. Moreover, the 3105 bottle cap material has a flat shape, no roller marks, and no oil spots, which is convenient for later printing and makes the pattern clear and legible.
