Zusammenfassung:	Provided is a mold release film which has excellent flexibility and heat resistance when heated, has good followability to a mold during resin molding, can be molded in accordance with the shape of the mold, has excellent mold release from the mold, and is easy to discard after use. The mold release film for mold molding is characterized in that the mold release film for mold molding is composed of two layers including a base material film having a thickness of 20-100 [mu] m and a mold release layer having a thickness of 0.1-10 [mu] m, and the base material film is polypropylene. 本发明提供一种脱模膜，其受热时的柔软性、耐热性优异，树脂成型时对模具的追随性良好，能够按照模具形状进行成型，且从模具的脱模优异，而且使用后的废弃也容易。一种模具成型用脱模膜，其特征在于，该模具成型用脱模膜由厚度为20～100μm的基材膜与厚度为0.1～10μm的脱模层这两层构成，并且所述基材膜为聚丙烯。
