PP film capacitors are widely used in AC applications for their excellent electrical characteristics such as low dielectric loss and high insulating resistance. We have developed PP film suitable for double metallizing and a new process which avoids blocking by decreasing surface energy of metallized layer. That process leads to improve moist-resistance of zinc metallized film. In this way, we have established a new technology for double metallized PP film and started its mass-production.
