The 8011/3105 coated aluminum sheet used to make aluminum caps is a high-quality aluminum alloy material. The coating material is selected from polyester, fluorocarbon and epoxy coatings with good adhesion and corrosion resistance. Aluminum caps are a commonly used packaging material with the advantages of light weight, high strength, beautiful and durable. Coated aluminum sheets can also be customized according to customer needs, such as printing patterns and texts, to increase the added value and market competitiveness of products. Aluminum alloy bottle cap materials are widely used in packaging in the pharmaceutical, cosmetic, beverage, alcohol and other industries.
8011 aluminum cap is an Al-Mn alloy. Due to its excellent performance, it is often used to make food packaging materials such as lunch boxes and sealing foils. As a coated aluminum sheet, it can further increase the corrosion resistance, aesthetics and functionality of the product.
3105 aluminum closure sheet belongs to aluminum-manganese alloy, which is a high-strength, corrosion-resistant and easy-to-process aluminum alloy material. It is widely used in decorative materials, handicrafts, manufacturing and construction. As a coated aluminum sheet, it is often used to make bottle caps, beverage packaging, etc., with good sealing and aesthetics.
