8021 aluminum foil manufacturers

Mingtai Aluminum is one of the large-scale 8021 aluminum foil manufacturers. The 8021-O aluminum foil substrates produced by the company are the source of aluminum foil for various lithium battery soft-package aluminum-plastic films and aluminum foil for medicinal blister packaging at home and abroad. .
Mingtai is also a large-scale aluminum foil manufacturer, which can undertake 3-2000 tons of aluminum foil raw material orders. The product quality is stable, the global export, and the price is affordable. You can communicate with us anytime and anywhere to get a detailed quotation.

8021 aluminum foil is used for battery soft pack

The battery soft pack is mainly composed of nylon layer, aluminum foil layer, heat sealing layer and adhesive used for bonding. Aluminum foil is the raw material of aluminum-plastic film for soft pack battery, mainly 8021 aluminum foil, 8079 aluminum foil, O temper. Aluminum plastic film has high barrier properties, good cold stamping formability, puncture resistance, electrolyte stability, high temperature resistance, insulation, etc. These performance characteristics also determine the high technical requirements of its production and the strict standards of raw materials.

Use of 8021 aluminum foil for blister packaging

Aluminum foil materials are stable and reliable in pharmaceutical packaging and are widely used. 8021 aluminum foil is used for blister packaging. The quality and performance requirements of pharmaceutical packaging aluminum foil are strict. High-quality pharmaceutical packaging has put forward better quality indicators such as toxic and harmful element content, plate shape, thickness, surface quality (including color difference, stripes, bright lines, bright spots, etc.), pinholes, heat resistance, and heat sealing strength of aluminum foil. High requirements, and these are precisely the quality problems that often occur in the production process of medicinal foils. In the production process of 8021 aluminum foil, Mingtai Aluminum should focus on the process links that are prone to these quality problems.

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 that of 8021 aluminum foil;
2. Aluminum foil 8011 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 bag and drug board is mostly 8021 aluminum foil. 8021 aluminum foil and 8079 aluminum foil are mostly used for blister aluminum and tropical aluminum with higher requirements on performance and elongation;
3. Aluminum foil 8011 is more widely used and can be used in many fields such as drug 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 requirements. Relatively high lithium battery soft-wrapped aluminum-plastic film and blister drug packaging.
