Different aluminum alloy for bottle caps

- 2020-01-17 -

Aluminum for bottle caps are mostly processed on a highly automated production line, so the requirements for material strength, elongation and dimensional deviation are very strict, otherwise cracks or creases will occur during processing. In order to ensure easy printing after the cap is formed, the surface of the bottle cap material is required to be flat, free of rolling marks, scratches and stains. The generally used alloy state is 8011-H14, 1060 and other winning numbers. The general thickness of the material specifications is 0.17mm ~ 0.5mm, width is 449mm ~ 79 6mm.

aluminum-plastic composite materials for cosmetic bottle caps

At present, the cosmetic bottle caps on the market use more plastic materials and aluminum-plastic composite materials. In comparison, aluminum-plastic composite materials have better sealing properties and more beautiful covers, which is the first choice for many high-end cosmetics. Kind of bottle cap material. The aluminum-plastic composite part of the aluminum-plastic composite bottle cap material will contact the liquid in the bottle, so 1060 aluminum sheet is often used as the aluminum sheet for bottle caps, and the thickness is generally between 0.17mm-0.5mm.

Advantages of aluminum alloy for bottle caps

1060 alloy is a lid-making method of aluminum-plastic combination. Because the aluminum-plastic combination part will contact the liquid in the bottle, most of them are used in the cosmetics industry, and some are used in the pharmaceutical industry. 8011 alloy is generally directly stamped. Forming a capping method, the performance of the two alloys 8011 is more superior, and the white wine cap. The red wine cap has a high utilization rate, the stamping depth can reach 60-80mm, and the oxidation effect is good, and the proportion of tinplate can reach 1 / 10, high recycling rate, environmental protection and other advantages, so it is accepted by more manufacturers and customers.
