Wave Slitting Zinc MPP Film

The metallized film has a self-healing function, and it naturally reverts to the electrical performance characteristic prior to the breakdown right after the partial breakdown of the film dielectric. The metalized film is covered on one or both sides of the edge or in the center to create a blank insulating strip without evaporating metal, which is known as the margin. The margin's width is also known as the margin.
