Worthwill 8021 aluminum foil is produced on state-of-the-art rolling and annealing equipment. The 8021 alloy provides significantly higher elongation than 8011, making it ideal for deep-draw applications such as battery pouch film and pharmaceutical packaging where pinhole resistance is critical.

We supply 8021 foil in a wide range of thicknesses from 0.02mm to 0.2mm, with custom slitting, precise tolerance control and clean, oil-free surfaces for lamination.
