<p><P>PROBLEM TO BE SOLVED: To provide a styrene-based resin laminated sheet which is excellent in surface gloss, strength, cost, mold fidelity, and high speed molding property, and generates less odor, and a container. <P>SOLUTION: This styrene-based resin laminated sheet is constituted of two layers or more of (A) a styrene-based resin biaxially oriented film having an average thickness of 10 to 300μm, (B) a styrene-based resin expanded body sheet having an average thickness of 0.5 to 5 mm, and (C) a styrene-based resin non-expanded body sheet having an average thickness of 0.05 to 2 mm, and at least one surface is covered with the styrene-based resin biaxially oriented film (A). The styrene-based biaxially oriented film (A) is obtained by biaxially orienting a resin of which the main component is a styrene-based resin, and the content of a styrene-based low molecular weight component is 50 to 3,000 ppm, the Vicat softening temperature is 103 to 130°C, the tensile modulus of elasticity at 120°C which is measured conforming to the ASTM-D882 method is 3 to 13 MPa in both of the longitudinal and transverse directions, and the heating shrinkage stress which is measured conforming to the ASTM-D1504 method is 400 to 2,000 kPa in both of the longitudinal and transverse directions. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
