Biaxially oriented polypropylene film for capacitors, metal film laminated film and film capacitors

摘要

PROBLEM TO BE SOLVED: To provide a biaxial orientation polypropylene film which exhibits excellent voltage resistance and reliability in capacitor applications for new energy and secures stable vapor-deposition workability and element workability.SOLUTION: There is provided a biaxial orientation polypropylene film for a capacitor whose peel strength is 3 g/5 cm or less and thickness t1 (μm) by a micrometer method is 2.5 μm or more and 7.0 μm or less.SELECTED DRAWING: Figure 1
