AA8011 aluminum sheets/coils for PP caps are aluminum alloy materials specifically designed for bottle cap sealing applications. This alloy belongs to the 8xxx series, primarily composed of aluminum, with small additions of iron (Fe) and silicon (Si) to enhance formability, tensile strength, oxidation resistance, and sealing performance.

PP caps (Pilfer Proof Caps) are widely used for sealing glass and PET bottles in the pharmaceutical, food, beverage, and cosmetics industries. AA8011 aluminum alloy offers excellent plasticity and superior deep drawing performance, allowing it to withstand significant deformation during cap processing without cracking or damage. Additionally, the material provides adequate strength, toughness, and elongation, ensuring the cap maintains integrity during use.

The surface of AA8011 aluminum coils is smooth and defect-free, making it ideal for printing and coating applications, significantly enhancing the aesthetic quality of PP tamper-proof caps. It is therefore a preferred material for manufacturing these caps.

Common Temper States of 8011 Aluminum Sheets/Coils

• H14 (Half-Hard): Suitable for caps requiring certain strength and rigidity (e.g., carbonated beverage bottles, spirits bottles).

• O (Soft): Suitable for deep drawing or spinning caps (e.g., pharmaceutical aluminum caps, cosmetic caps).

MC Aluminum produces 8011 aluminum coils using roll coating technology, applying color to the aluminum coil before slitting it into sheets. Compared with traditional methods, this ensures better coating surface quality, excellent adhesion, superior MEK test performance, and lower production costs.
