The main aluminum raw materials of medicinal aluminum foil are 1100, 1145, 1200, 1235, 8011, 8021, және 8079 aluminum alloys. Олардың арасында, PTP алюминий фольгасы 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).
