Lithium battery shell protective film tape
Mainly used for wrapping the outer shell of square aluminum shell power batteries, it can protect the battery from being scratched by external objects after bonding, help the battery to insulate the shell after being charged, and prevent leakage from occurring.
Using polyester film with good scratch resistance, puncture resistance, and excellent electrical insulation performance as the substrate, it can effectively protect the surface of the battery. According to the process requirements of different lithium battery manufacturers, there are single-layer and double-layer structure products to choose from. At the same time, in order to reduce the time of tape roll change during use and facilitate the application of structural adhesive, and improve battery production efficiency, we also provide products with release film.
