The difference between 8011 aluminum foil and 8021 aluminum foil
The packaging materials used in the pharmaceutical packaging industry are mostly aluminum foil metal materials. Compared with other types of pharmaceutical packaging aluminum foil has the advantages of high barrier properties, light protection, safety, and harmlessness.
As aluminum foil is widely used as a packaging material in the pharmaceutical industry, the commonly used models are 8011 aluminum blister foils and 8021aluminum blister foils, which have much excellent operability as medicinal foil packaging. In the production process, it is heat-sealed with various plastic substrates and made into packaging for packaging pharmaceutical tablets, capsules, pills, etc. It has the characteristics of oxygen resistance, moisture resistance, good sealing, and pollution prevention.
8011 aluminum foil and 8021 aluminum foil are more and more common in the form of blister packaging in the packaging of health food, pharmaceutical tablets, and capsules. They are one of the pharmaceutical packaging materials with good development prospects. The annual share of aluminum foil used for pharmaceutical packaging is also increasing. High, but there are many differences between the two medicinal packaging aluminum foils.
The difference in the alloy is the most direct place where the two aluminum foils differ. 8011 aluminum foil contains Mn and Mg elements, while 8021 aluminum foil does not contain these two elements, so the strength and corrosion resistance of 8011 aluminum foil is higher than that of 8021 aluminum foil. Commonly used aluminum foil blister, PTP medicinal aluminum foil alloy usually adopts 8011-H18 state aluminum foil, 8011-O state aluminum foil.
Because of the addition of different alloys, the two aluminum foils also differ in their properties. The strength of 8011 aluminum foil is higher. However, if it is the elongation and puncture resistance in the same state, the performance of 8021 aluminum foil is better than that of 8011 aluminum foil. Generally, manufacturers will choose the corresponding aluminum foil in the drug packaging according to their needs. For the aluminum foil coating on the back of some medicine capsules, the 8021 aluminum foil is mostly used. If the blister aluminum requires higher sealing and elongation, the 8021 aluminum foil is mostly used.
In addition to the more common use of 8011 aluminum foil and 8021 aluminum foil in pharmaceutical packaging, there are some other uses. 8011 aluminum foil can also be used in food packaging, lunch box material, tape foil, bottle cap material, and many other fields. 8021 aluminum foil can also be used for high-demand lithium battery soft-package aluminum-plastic film.
The alloy components added to the two aluminum foils are different, and there are certain differences in the production process, so the prices of 8011 and 8021 aluminum foils also have some deviations, and the price of 8021 aluminum foils is relatively high.
8011 aluminum foil and 8021 aluminum foil are two kinds of pharmaceutical packaging aluminum foil widely exported by HWPFP (Huawei Pharma Foil Packaging). Huawei Aluminum medicinal aluminum foil has excellent moisture resistance, shading performance, and high barrier ability, non-toxic, tasteless, safe, and hygienic. Continuously provide high-quality medicinal aluminum foil products for more than 40 countries around the world.
