8021 Aluminum foil has excellent moisture resistance, light shading and high barrier ability. Non-toxic and tasteless, safe and hygienic. Aluminum foil after compounding, printing, and gluing is widely used as packaging materials, and it is the main product of food packaging and battery soft packaging aluminum foil.

During the production process, 8021 aluminum foil has passed multiple tests such as bacteria and mold. The content of heavy metals must not exceed 0.25ppm to ensure that the finished product is non-toxic, tasteless, safe and hygienic. Therefore, 8021 aluminum foil is often used as medicinal aluminum foil, Use aluminum foil for packaging.

The difference between 8011 aluminum foil and 8021 aluminum foil:

1. 8011 aluminum foil contains Mn and Mg elements, but 8021 aluminum foil does not contain these two elements, so the strength and corrosion resistance of 8011 aluminum foil are higher than 8021 aluminum foil;

2. The strength of aluminum foil 8011 is high, but the corresponding elongation and puncture resistance under the same state are lower than 8021 aluminum foil. 8021 aluminum foil and 8079 aluminum foil are mostly used for blister aluminum and tropical aluminum that require higher performance and elongation;

3. The use of aluminum foil 8011 is more extensive, and can be used in many fields such as pharmaceutical packaging, food packaging, lunch box materials, tape foil, cable foil, milk cap material, bottle cap material, etc., while 8021 aluminum foil is relatively expensive and is mostly used for requirements Relatively high lithium battery soft package aluminum plastic film and blister drug packaging.
