PROBLEM TO BE SOLVED: To provide a polystyrene-based resin laminated foamed sheet good in moldability and moldable of a container excellent in balance of strength and appearance, good in processability and excellent in printability immediately after molding and low in anisotropy of compression strength, and also reducing occurrence of chips and cutting dust at the time of punching. SOLUTION: This polystyrene-based resin laminated foamed sheet is obtained by laminating a polystyrene-based resin non-foamed film whose basis weight is 100-210 g/m<SP>2</SP>on a polystyrene-based foamed sheet made by extrusion foaming of a base resin comprising 95-60 wt.% of a polystyrene-based resin obtained by suspension polymerization process and 5-40 wt.% of a polystyrene-based resin obtained by bulk polymerization process. Herewith a container excellent in deep drawability and having the characteristics can be obtained. COPYRIGHT: (C)2008,JPO&INPIT |
