8011 aluminum foil and 8021 aluminum foil are commonly used pharmaceutical packaging materials. Their differences in pharmaceutical packaging are:

Aluminum foil alloy composition is different: 8011 aluminum foil is a single-layer aluminum foil, the aluminum content is about 99%, and the rest is trace elements; 8021 алюминий фольга is a double-layer aluminum foil, the aluminum content is also about 99%, but a small amount of other metals such as silicon and copper are added .

The scope of application is different: 8011 aluminum foil is suitable for general pharmaceutical packaging, such as capsules, таблеткалар, granules, жана башкалар; 8021 aluminum foil is suitable for high-end pharmaceutical packaging, such as oral liquids, injections, жана башкалар.

Different physical properties: Due to the double-layer structure of 8021 алюминий фольга, it has better physical properties such as barrier property, oxidation resistance, corrosion resistance and high temperature resistance than single-layer 8011 алюминий фольга.

The production process is different: 8011 aluminum foil often adopts conventional rolling production process; while 8021 aluminum foil adopts more complex composite production process, and the production cost of double-layer aluminum foil is higher.

To sum up, the main difference between 8011 алюминий фольга жана 8021 aluminum foil in pharmaceutical packaging lies in the aluminum foil alloy composition, scope of application, physical properties and production process.
