Premium 8011 Aluminum Foil Tape – Heat-Resistant & Durable for Industrial Sealing

When selecting the base material for premium adhesive tape applications, 8011 aluminum foil stands out as a proven industry standard. Trusted by leading tape manufacturers worldwide, 8011 alloy delivers the optimal balance of strength, formability, and surface quality required for demanding sealing, shielding, and bonding applications.

Why 8011 Alloy?

8011 aluminum belongs to the 8xxx series alloy family, with a controlled Al-Fe-Si chemical composition: silicon typically ranges from 0.50% to 0.90%, and iron from 0.60% to 1.00%. This precise formulation endows the foil with:

• Excellent surface quality – clean, uniform, and good flatness, ensuring superior tape appearance and adhesive bonding
  

• Strong mechanical properties – high tensile and shear strength, tear resistance, and puncture resistance for reliable in-service performance

• Superior barrier performance – outstanding moisture-proof, light-blocking, and gas-barrier capabilities
