What’s the difference between aluminum foil bags and PET aluminum bags? From the above features, we have summarized 8 points:

  1. The appearance is different. The aluminum foil bag is opaque, while the PET aluminum bag faces the light, and the light can be seen through the bag.
  2. In terms of cost, the material used in the aluminum foil bag is pure aluminum foil with high purity and soft material. The PET aluminum bag contains composite materials, which are brittle materials.
  3. In terms of performance, aluminum foil bags are better than PET aluminum bags in terms of moisture resistance and temperature reduction. Aluminum foil bags completely avoid light, and PET aluminum bags are a shading effect.
  4. In terms of use, aluminum foil bags are more suitable for vacuum pumpings, such as cooked food, meat, and other products. PET aluminum bags are suitable for tea, powder, electronic products, etc.
  5. Aluminum foil is not easy to burn with fire, and gray aluminum slag will be left after burning. Different plastic film combustion conditions can occur when PET aluminum film is burned with fire.
  6. Aluminum foil bags are easy to fold and rebound quickly. The aluminum layer is broken.
  7. The aluminum foil bag is not easy to rebound after twisting, and there will be no obvious cracks.
  8. You can touch two kinds of bags with your hand. Aluminum foil bags are thick, hard, and heavy. PET aluminum bags are softer and lighter than aluminum foil bags.
