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 i-aluminium foil 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, amaphilisi, granules, njll.; 8021 aluminum foil is suitable for high-end pharmaceutical packaging, such as oral liquids, injections, njll.

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

The production process is different: 8011 aluminum foil often adopts conventional rolling production process; ngenkathi 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 i-aluminium foil kanye 8021 aluminum foil in pharmaceutical packaging lies in the aluminum foil alloy composition, scope of application, physical properties and production process.
