BIAXIALLY STRETCHED POLYPROPYLENE FILM, METALLIZED FILM, METALLIZED FILM ROLL AND FILM CAPACITOR

摘要

A biaxially stretched polypropylene film which has a thickness of from 1.0 µm to 3.5 µm, a tensile fracture stress at 135°C of 70 MPa or more in a first direction, and a difference between the tensile fracture stress at 125°C in the first direction and the tensile fracture stress at 135°C in the first direction of from 0 MPa to 15 MPa (inclusive).
