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, thiab 8079 aluminium alloys. Ntawm lawv, PTP aluminium ntawv ci 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 sealing.
Table 1 shows the mechanical properties of aluminum foil in different states of different alloys (thickness of aluminum foil is 0.020mm).
