Biaxially oriented polypropylene film, polypropylene film roll, and metallized polypropylene film

Abstract

To provide a biaxially stretched polypropylene film that enables reduced failures in a cutting process due to nonuniform stretching in a longitudinal direction, and also enables improved yield of a capacitor element having high-temperature tolerability.SOLUTION: A biaxially stretched polypropylene film is provided, the biaxially stretched polypropylene film having a thickness of 1.5 μm or more and 6.6 μm or less. In a 100 m section of the biaxially stretched polypropylene film in a longitudinal direction, 11 sites were measured at regular intervals in the longitudinal direction, so that a change width in a slow axis angle fell in a range of 0.0° or more to 6.5°or less.SELECTED DRAWING: None
