8011 aliuminis buvol and 8021 aliuminio folija yra dažniausiai naudojamos farmacijos pakavimo medžiagos. Jų skirtumai farmacinėje pakuotėje yra:

Aliuminio folijos lydinio sudėtis skiriasi: 8011 aluminum foil is a single-layer aluminum foil, the aluminum content is about 99%, and the rest is trace elements; 8021 aliuminio folija 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, tokių kaip kapsulės, tabletės, granulės, ir tt; 8021 aluminum foil is suitable for high-end pharmaceutical packaging, such as oral liquids, injections, ir tt.

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

The production process is different: 8011 aluminum foil often adopts conventional rolling production process; kol 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 aliuminio folija ir 8021 aluminum foil in pharmaceutical packaging lies in the aluminum foil alloy composition, scope of application, physical properties and production process.
