<p>PROBLEM TO BE SOLVED: To provide a mat-like polypropylene multilayer stretched film having the low shrinkage rate equivalent to that of a PET film at 150°C and high rigidity.SOLUTION: The mat-like polypropylene multilayer stretched film is obtained by forming a polypropylene resin mat layer (B), which has the surface roughness being 0.15μm or larger three-dimensional surface average roughness, on at least one surface of a polypropylene resin layer (A). The mat-like polypropylene multilayer stretched film has 9% or lower thermal shrinkage rate in the MD direction and in the TD direction at 150°C, 0.6 J or higher impact strength and 40% or higher haze.</p> |
