Cosmetics have become an essential part of daily life—not only enhancing appearance but also contributing to skin health and overall well-being. As the cosmetics industry increasingly pursues refined packaging aesthetics and higher product protection standards, products such as powders, creams, and liquids demand enhanced packaging sealability and stability. As a result, aluminum alloy closures have become an indispensable choice in cosmetic packaging, offering outstanding performance in sealing, anti-corrosion, and anti-counterfeiting.

Aluminum alloy closures are a new type of bottle sealing material, combining both aesthetic appeal and functionality, while effectively preventing counterfeit or substandard products. Consequently, aluminum alloy bottle cap materials are widely used in the sealing of bottles for beverages, wine, cosmetics, pharmaceuticals, and more in both domestic and international markets.

Aluminum strips used for cosmetic caps offer excellent formability and a natural silver sheen. Common grades include 8011 and 1070 aluminum strips, typically ranging in thickness from 0.17mm to 0.5mm.
