Cold forming aluminum foil, also known as Alu Alu foil, is the pinnacle of pharmaceutical packaging solutions. Designed to protect the most sensitive medications, this material offers unparalleled barrier properties, ensuring the integrity and efficacy of pharmaceuticals.
The multilayered structure of our Cold Form Aluminum Foil includes an OPA film, adhesive layers, aluminum soft foil, and a PVC film. Each layer is crafted for maximum protection and performance. The thickness of aluminum foil is generally 45-60 microns, and the commonly used alloys are 8011, 8079, or 8021.
