The Difference Between 8011 Aluminum Foil and 8021 Aluminum Foil

With the development and progress of society, people's requirements for the required product performance are becoming more and more strict, which forces manufacturers to choose strict requirements for production raw materials, and traditional metal materials have gradually been unable to meet the needs of manufacturing high-performance products. Environmental protection is a hot topic nowadays. As an environmentally friendly, non-toxic and high-performance material, aluminum foil is widely used in line with the trend of the times. As the new favorite of the times, 8011 aluminum foil is widely used in pharmaceutical packaging, food packaging, cable foil, milk capping material, sealing foil and other fields.

1. Introduction of 8011 aluminum foil and 8021 aluminum foil

(1) 8011 aluminum foil

8011 aluminium foil is a series of aluminum plates, belonging to the 8xxx series of alloy aluminum plates. It is added with Al-Fe-Si elements, and its alloy properties have relatively high advantages in more than 1% of the total alloying elements. 8011 is often used as aluminum foil, and its performance is better than pure aluminum foil. It is widely used in aluminum foil, and aluminum sheet is not commonly used.

(2) 8021 aluminum foil

8021 aluminum foil is the main product of food packaging and battery soft package aluminum foil. 8021 commercial aluminum foil has excellent moisture resistance, shading and extremely high barrier capabilities. Non-toxic, tasteless, safe and hygienic. The aluminum foil after compounding, printing and gluing is widely used as a packaging material.

2. The difference between 8011 aluminum foil and 8021 aluminum foil

(1) 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 are higher than those of 8021 aluminum foil.

(2) 8011 aluminum foil has high strength, but the corresponding elongation and puncture resistance in the same state are lower than that of 8021 aluminum foil. Therefore, in drug packaging, the aluminum foil coating on the back of the drug board is mostly 8021 aluminum foil, which is not good for sealing. Blister aluminum and tropical aluminum with higher elongation requirements mostly use 8021 aluminum foil and 8079 aluminum foil.

(3) 8011 aluminum foil is more widely used and can be used in many fields such as pharmaceutical packaging, food packaging, lunch box material, tape foil, cable foil, milk cap material, bottle cap material, etc., while 8021 aluminum foil is relatively expensive and is mostly used for In the packaging of lithium battery soft-pack aluminum-plastic film and blister medicines with relatively high requirements.
