BOPP Capacitor Film (clear transparent film)

Category: Bopp Capacitor Film

Features:

With one side is corona treatment and the reverse side is clear smooth .It homogenizes in thickness , low dielectric loss, high electric strength ,excellent procession . single side corona treated for the Zn or Zn/Al metallized.

Mainly used for dielectric materials for the low-voltage and parallel power capacitor, capacitor for alternating current motor and direct current capacitor.
