One side is corona treatment, other side is smooth, it is the base film which one side can be metallized
According to the used requirement, a layer or more layers of metal are metallized on the surface of the film...It makes the capacitor has a good elf-healing. Thickness uniformity, good wind ability.
It is the material of electrode and Dielectric for metallizing and self-healing capacitor.
Al metallized film: 2 ~ 4 Al/Zn alloy metallized film: Normal 5 ~ 10, heavy edge 1 ~ 4.
