Abstract:
There is provided a thermoplastic resin film which is high in tear resistance. The thermoplastic resin film according to the present invention is provided with a plurality of first thermoplastic resin layers each containing a thermoplastic resin and a plurality of second thermoplastic resin layers each containing a thermoplastic resin, and has a multilayer structure in which the first and second thermoplastic resin layers are laminated in the thickness direction, the number of laminations in total of the first and second thermoplastic resin layers in the thickness direction is greater than or equal to 5, the ratio of the total thickness of the first thermoplastic resin layers to the total thickness of the second thermoplastic resin layers is greater than 1, the tensile modulus of elasticity of the respective first thermoplastic resin layers is less than or equal to 30 MPa, and the tensile modulus of elasticity of the respective first thermoplastic resin layers is greater than or equal to 280 MPa.
