Abstract
Abstract A thermoplastic resin stretched film laminate is described, which comprises a biaxially stretched thermoplastic resin film base layer having provided on one or both sides thereof a surface layer, the surface layer comprising a uniaxially stretched thermoplastic resin film containing 3 to 30% by weight of a petroleum resin, 30 to 65% by weight of precipitated calcium carbonate having a particle size of 0.1 to 3 µm, and 32 to 67% by weight of a thermoplastic resin and having a thickness of not less than 2 µm.
