To provide a thermoplastic resin laminated film excellent in flexibility, the adhesion with a coating layer of printing ink or a pressure-sensitive adhesive and heat resistance and having good secondary processability.
The thermoplastic resin laminated film is based on a thermoplastic resin and comprises three or more laminated layers and characterized by that 90°C creep compliance is 110 GPa-1 or less, tensile elastic modulus in a flow direction at 20°C is 500 MPa or less, surface and back layers are based on polyethylene, a degree of crystallization is 68% or less and a wet index is 36 dyn/cm or more. Further, this laminated film includes at least one layer comprising a mixture of a copolymer resin containing at least two monomers selected from ethylene, propylene and butene and a polypropylene resin and the surface and back layers there are based on a mixture of a straight low density polyethylene resin comprising an ethylene/α-olefin single site copolymer and a low density polyethylene and compounded with a lubricating agent in an amount of 500 ppm or less.
