8011 bha aluminiuml and 8021 tha foil alùmanum mar stuthan pacaidh cungaidh-leigheis gu cumanta. Tha na h-eadar-dhealachaidhean aca ann am pacadh cungaidh-leigheis:

Tha co-dhèanamh alloy foil alùmanum eadar-dhealaichte: 8011 aluminum foil is a single-layer aluminum foil, the aluminum content is about 99%, and the rest is trace elements; 8021 foil almain 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, leithid capsalan, clàran, gràinneagan, etc.; 8021 aluminum foil is suitable for high-end pharmaceutical packaging, such as oral liquids, injections, etc.

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

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

Gus geàrr-chunntas, the main difference between 8011 foil almain agus 8021 aluminum foil in pharmaceutical packaging lies in the aluminum foil alloy composition, scope of application, physical properties and production process.
