  • Publication number: 20230235135
    Abstract: Provided is a biaxially oriented polypropylene film that has high stiffness and can easily retain a bag shape when made into a packaging bag even if the film is made thinner, and at the same time, that can maintain water vapor barrier properties even if the film is made thinner, and has few wrinkles in and around the sealed portion when heat-sealed to make a packaging body. The biaxially oriented polypropylene film satisfies the following (1) and (2): (1) a half width of a peak derived from an oriented crystal in a width direction in angular dependency of a (110) plane of polypropylene?-type crystal obtained by wide-angle X-ray diffraction measurement is 26° or smaller; (2) the ratio of (III) to the total of a crystalline component (I), a restrained amorphous component (II), and an unrestrained amorphous component (III) classified by pulse NMR according to solid-echo method is 7% or lower.
