Abstract: A thermoplastic resin film of the present invention contains at least a base layer containing a thermoplastic resin and a heat seal layer containing a thermoplastic resin; a melting point of the thermoplastic resin contained in the heat seal layer is lower than a melting point of the thermoplastic resin of the base layer; a core roughness depth Rk of a surface of the heat seal layer being from 1.2 to 9.0 μm; and a ratio Rzjis/Rk of a ten point height of roughness profile Rzjis to a core roughness depth Rk of the surface of the heat seal layer measured in accordance with JIS B0601:2013 Appendix 1 being from 2.0 to 9.0.
