(57) [Summary] [Purpose] Adhering to the flexibility, elasticity, moisture permeability, cold resistance, flex resistance, toughness, etc. of urethane hot melt film, and further laminating it with fabric or foam sheet. Provided is a hot mel film which, when heated, causes high interlayer adhesive strength and does not impair the inherent properties of fabrics, foamed sheets and the like. [Structure] Both outer layers are made of a thermoplastic polyurethane resin (A) having an outflow starting temperature of 150 ° C. or lower, and the core layer is 20 to 100 ° C. higher than the outflow starting temperature of the thermoplastic polyurethane resin (A) used for both outer layers. It is characterized by comprising a thermoplastic polyurethane resin (B) having a high outflow starting temperature. |
