BOPET capacitor film BOPET capacitor film (Polyester capacitor film) have two items: clear/transparent BOPET capacitor film and silver metallized BOPET capacitor film 1. BOPET capacitor film were used for film-capacitor (and other electrical insulation material.) which features dielectric strength, dielectric constant and volume resistance, low dielectric loss, good mechanical performance and dimension stability. BOPET capacitor film also called PET Capacitor film,clear Polyester capacitor film,transparent Polyester capacitor film, Thickness:3-12UM Width: 500,620,910,980,1010,1300 MM Net weight per roll about: 50KGS/roll Inner plastic tube core: 3\',6\'(76MM ,152MM ) 2. BOPET metalized VM/--Zn/Al capacitor film (Metallized BOPET Capacitor Film,sliver PET Capacitor film). Thickness:3-12UM Width: 500,620,910,980,1010,1300 MM
