Abstract
The present invention provides a mold release film including a resin layer provided on one surface of a polyester film, wherein the resin layer includes 100 parts by mass of a polypropylene-based modified polyolefin resin with the proportion of a modifying component of 1 to 10% by mass and 1 to 50 parts by mass of a cross-linking agent; the peel strength between the resin layer and a pressure-sensitive adhesive measured by bonding a rubber-based pressure-sensitive adhesive to the resin layer exceeds 3.0 N/cm; and the residual adhesion rate of a pressure-sensitive adhesive after bonding an acrylic pressure-sensitive adhesive to the resin layer is 80% or more.
