Document Type and Number:
Japanese Patent JP2020124905
Kind Code:
A
Abstract:
To provide a metal layer-integrated polypropylene film capable of suppressing peeling of a metallikon electrode while securing room for material selection of a polypropylene film and room for adjustment of production conditions of a polypropylene film.SOLUTION: There is provided a metal layer-integrated polypropylene film having a polypropylene film and a metal layer laminated on one surface or both surfaces of the polypropylene film, wherein when a thermal shrinkage in a first direction of a polypropylene film before laminating a metal layer is defined as A and a thermal shrinkage in a first direction of the metal layer-integrated polypropylene film is defined as B, the thermal shrinkage ratio [(thermal shrinkage B)/(thermal shrinkage A)] between a thermal shrinkage A and a thermal shrinkage B is 0.25 or more and 0.60 or less.SELECTED DRAWING: Figure 1
