The difference between hard aluminum foil (H18) and soft aluminum foil (O) for PTP medicinal foil

The main aluminum raw materials of medicinal aluminum foil are 1100, 1145, 1200, 1235, 8011, 8021, and 8079 aluminum alloys. Among them, PTP aluminum foil produced with 8011 alloy primary aluminum has high tensile strength, elongation, and rupture strength, which is similar to PVC heat. There is less chance of the aluminum foil breaking when …
