Product Description8021 8079 Aluminum foil for battery surface packaging aluminum-plastic composite film 0.016 0.05mm

Aluminum foil for lithium battery soft pack aluminum-plastic film
In the three-layer structure of aluminum-plastic composite film, aluminum foil, as the middle layer, mainly plays the role of preventing the infiltration of water vapor outside the battery and preventing the leakage of internal electrolyte. In order to ensure the long-term stable and safe operation of the battery, the aluminum foil for aluminum-plastic film needs to have extremely high barrier properties, good cold stamping formability, puncture resistance and stability.

8021 aluminum foil performance advantages
1.It has excellent moisture resistance, light shielding and extremely high barrier ability.
2.It is non-toxic and odorless, safe and hygienic.
3.Aluminum foil after compounding, printing and gluing is widely used as packaging material.
