Biaxially Stretched Polypropylene Film Metallized Film And Film Capacitor
Abstract: The present invention provides a biaxially stretched polypropylene film which shows excellent withstand voltage and safety even when used in capacitors for high voltage use and with which stable processability into elements is ensured. The biaxially stretched polypropylene film has projections on both surfaces and is characterized by having a thickness (t1) of 1 3 µm a longitudinal direction tensile strength of 120 250 MPa and a transverse direction tensile strength of 250 400 MPa. The film is further characterized in that each surface has a minimum projection height P of 100 nm or more and a maximum projection height P of 1 600 nm or less and that when one of the surfaces is expressed by surface A and the other is expressed by surface B then all of relationships (1) to (3) are satisfied. 0.5=Pa/Pa=1.0 (1) 0.5=Pb/Pb=1.0 (2) 600=Pa+Pb=1 200 (3)
