Zusammenfassung:PROBLEM TO BE SOLVED: To provide a laminated film which does not need an intermediate layer and is provided with an optimum peeling condition. SOLUTION: The laminated film is composed of a thermoplastic polyester resin layer having a moisture transmittance of 500-10,000 g/(m224 h) and a polyolefin resin layer. The peel strength between the two layers is 0.01-0.25 N/25 mm. The melt index (MI) of the polyolefin resin is preferably 2-20, and the polyolefin resin is preferably low density polyethylene (LDPE).
