8011 aluminum foil and 8021 Ang aluminum foil ay karaniwang ginagamit na mga materyales sa packaging ng parmasyutiko. Ang kanilang mga pagkakaiba sa pharmaceutical packaging ay:

Ang komposisyon ng haluang metal ng aluminyo foil ay naiiba: 8011 aluminum foil is a single-layer aluminum foil, the aluminum content is about 99%, and the rest is trace elements; 8021 aluminyo palara 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, tulad ng mga kapsula, mga tablet, mga butil, atbp.; 8021 aluminum foil is suitable for high-end pharmaceutical packaging, such as oral liquids, injections, atbp.

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

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