Aluminum foil — the best metal packaging material

Aluminum foil is a soft material. After rolling the aluminum sheet, it has a thinner thickness and can be used as a good packaging material. Aluminum foil is most commonly used as a packaging material for food. It can also be used as a packaging material for pharmaceutical products after fine processing.

Aluminum foil for pharmaceutical packaging

Aluminum foil for pharmaceutical packaging

Aluminum foil is one of the few metal materials that can be used as pharmaceutical packaging materials. There are many types of pharmaceutical packaging, such as blister foil, cold-formed aluminum foil, heat-sealed foil, etc. In the 1000-8000 series, 8011, 8021 and 8079 in the 8000 series of aluminum alloys are often used as pharmaceutical packaging materials. In cold-formed pharmaceutical packaging, 8011 and 8021 aluminum foils are two aluminum foil alloys that can meet various performance requirements.

Which cold-formed aluminum foil is better?

Both 8011 aluminum foil and 8021 aluminum foil are suitable materials for pharmaceutical cold-formed aluminum applications, but they have different characteristics, and the choice depends on the specific requirements of the application. When discussing which of 8011 aluminum foil and 8021 aluminum foil is more suitable for pharmaceutical cold-formed aluminum foil, it is necessary to comprehensively consider the performance characteristics, application scenarios, and specific requirements of pharmaceutical aluminum foil.

Performance comparison of 8021 and 8011 aluminum foil

8011 aluminum foil

Al-Fe-Si elements are added, and the alloy performance is superior. High strength, but the elongation and puncture resistance under the same state may be relatively low.
It has excellent moisture-proof, light-shielding and barrier properties. The surface is clean, the color is uniform, there is no spot, it is flat and has no pinholes. Non-toxic and odorless, safe and hygienic.

8021 aluminum foil

It does not contain Mn and Mg elements, but has the characteristics of other alloy elements. It has strong mechanical properties, high anti-blasting performance, and strong anti-puncture and tearing performance.
Excellent moisture-proof, light-shielding ability and high barrier ability. The surface is also clean, uniform in color, without oil stains, flat and without pinholes. Through multiple tests, the heavy metal content is low, ensuring safety and hygiene.

8021 vs 8011 Application scenarios

8011 aluminum foil is widely used in blister packaging in pharmaceutical packaging, such as pharmaceutical capsules, tablets, etc.
It is also used in food packaging, lunch box materials, tape foil, cable foil and other fields.

8021 aluminum foil is mainly used for cold-formed pharmaceutical aluminum foil packaging, and is also suitable for lithium battery soft package aluminum plastic film, etc. In pharmaceutical packaging, it is often used for aluminum foil coating on the back of medicine capsules and medicine plates.

Comparison of strength and elongation

8011 aluminum foil has high strength, but relatively low elongation and puncture resistance; while 8021 aluminum foil has good elongation and puncture resistance while maintaining high mechanical properties. For cold-formed aluminum foil, good elongation and puncture resistance help maintain the integrity and sealing of the aluminum foil during the forming process.

Requirements for cold-formed medicinal aluminum foil

Medicinal aluminum foil needs to meet basic requirements such as moisture-proof, light-shielding, strong barrier ability, non-toxic and tasteless, safe and hygienic. At the same time, cold-formed aluminum foil also needs to have good mechanical properties and processing properties. Both 8011 and 8021 can meet these requirements.

Differences in medicinal packaging

Although 8011 aluminum foil is widely used in pharmaceutical packaging, 8021 aluminum foil has more specific advantages in cold-formed medicinal aluminum foil packaging. Especially in occasions with high requirements for sealing and elongation, 8021 aluminum foil is more suitable. 8021 aluminum foil is more suitable for medicinal cold-formed aluminum foil. While maintaining high strength and excellent moisture-proof, light-shielding and barrier properties, it also has better elongation and puncture resistance, and can meet the specific requirements of medicinal cold-formed aluminum foil.
