Know the power battery aluminum plastic film

With the popularity of electric vehicles, the demand for power batteries is increasing day by day, and the demand for aluminum-plastic film as a part of the power battery is also increasing day by day. However, the aluminum-plastic film industry has been monopolized by foreign companies before. With the strong domestic demand for aluminum-plastic films and dissatisfaction with the lagging after-sales service of foreign companies, some aluminum-plastic film companies have risen to meet the domestic market demand for aluminum-plastic films.

The role of aluminum foil in aluminum plastic film

In the three-layer structure of aluminum-plastic composite film, aluminum foil is used as the middle layer, and 8021 aluminum foil and 8079 aluminum foil are used as base materials, which mainly prevent the infiltration of water vapor from the outside of the battery and prevent the seepage of the internal electrolyte. In order to ensure the long-term stable operation of the battery, the aluminum foil for aluminum-plastic film needs to have high barrier properties, good cold stamping formability, puncture resistance and stability.

The main products of battery soft package aluminum foil are 8021 aluminum alloy coils. The surface of the 8021 aluminum foil produced by Mingtai is clean, smooth and free of oil, and it can bond well in the process of aluminum-plastic film lamination, and it is not easy to fall off and delaminate. At the same time, the product has better stamping and puncture resistance.

8021 aluminum foil manufacturer

The thickness range of Mingtai 8021 aluminum foil is 0.018mm-0.2mm, and the width can be controlled at 100-1650mm according to customer requirements. 8021 aluminum foil is the main product of food packaging and battery soft package aluminum foil. 8021 aluminum foil has excellent moisture-proof performance, light-shielding and extremely high barrier ability. Non-toxic and tasteless, safe and hygienic. Aluminum foil after compounding, printing and gluing is widely used as packaging material.
