Title:
POLYPROPYLENE FILM, LAMINATE, PACKAGING MATERIAL, PACKAGED BODY, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/153327
Kind Code:
A1
Abstract:
This polypropylene film includes particles. Regarding the polypropylene film, when the direction in which the shrinkage percentage is largest at 140°C in a temperature increase process for a thermomechanical analysis is defined as X1 direction, and when the temperature at which a 1% shrinkage occurs in the X1 direction is defined as X1Ts, X1Ts is 100-160°C. The particles are metal particles and/or inorganic compound particles. Provided is a polypropylene film that has, even while using a recycled deposited film, excellent thermal dimensional stability, and high oxygen barrier properties and water vapor barrier properties.
