Abstract

The present invention addresses the problem of providing a molding film having exceptional molding properties during molding processing. The main object of the present invention is a molding film having a resin layer (X layer) on at least one surface of a polyester film, the molding film being characterized in that the polyester film has a configuration in which layers (A layers) having a thermoplastic resin A as a main component, and layers (B layers) having a thermoplastic resin B different from the thermoplastic resin A as a main component, are laminated in an alternating manner in the thickness direction so as to reach a total of 51 or more layers.
