<p><P>PROBLEM TO BE SOLVED: To provide a polystyrene-based resin laminated foamed sheet which has excellent balance in an elongation in MD direction and TD direction of the polystyrene-based resin laminated foamed sheet, and manufactures a molded body having less strength variation even in manufacturing multiple patterning and deep drawn shaped molded body. <P>SOLUTION: The polystyrene based resin laminated foamed sheet is formed by laminating a thermoplastic resin non-foamed film on one side or both sides of polystyrene based resin foamed sheet. The thickness of the polystyrene based resin laminated foamed sheet is within the range of 1.5-3.0 mm, a basis weight per 1 m<SP>2</SP>thereof is 310-420 g/m<SP>2</SP>, and a tensile strength in an extrusion direction and the width direction, measured based on JIS K7161 (1994) is within the range of 50-75 N. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
