Wholesale 8021 alloy aluminum foil

what is 8021 alloy aluminum foil？

8021 alloy aluminum foil has excellent moisture resistance, shading, and extremely high barrier ability: elongation, puncture resistance, and strong sealing performance.

The aluminum foil after compounding, printing, and gluing is widely used as a packaging material. Mainly used for food packaging, blister drug packaging, soft battery packs, etc.

The Advantages Of  8021 aluminum foil

(1) The surface is clean and hygienic, and no bacteria or microorganisms can grow on its surface.
(2) It is a non-toxic packaging material, which can be in direct contact with food without any danger of harming human health.
(3) It is an odorless and odorless packaging material, which will not make the packaged food have any peculiar smell.
(4) No matter whether in high temperature or low temperature, there will be no oil penetration phenomenon.
(5) High hardness and high tensile strength, but its tear strength is small, so it is easy to tear.
(6) As an opaque packaging material, it is a good packaging material for products exposed to sunlight, such as margarine.
(7) It has good plasticity, so it can be used for packaging products of various shapes. Various shapes of containers can also be arbitrarily formed.

Battery Soft Package Aluminum Foil

The commonly used specification of battery soft-pack aluminum foil is 0.035-0.055mm.

8021’s plain aluminum foil material has good performance and extensibility, and the commonly used thickness is 0.04mm. The main advantage is that it is used in deep-drawing packaging materials.

aluminum foil battery Have The Following Advantages:

1. High energy density. The general battery capacity can be about 2200mAh, so the energy density is about 500Wh/L, and the energy density of the polymer battery is now
   Stage mass production can be close to 600Wh/L.
2. Good safety. Polymer batteries do not have this problem. Even in the same situation, due to the low strength of the packaging film, as long as the e-air pressure is slightly higher, it will rupture and will not explode.
   Explosion, the worst case is burning.
