<P>PROBLEM TO BE SOLVED: To provide a laminate foamed sheet by which a molding excellent in heat resistance can be produced, and which facilitates material recycling of remnants produced in producing the molding, this molding itself, etc. <P>SOLUTION: The method for producing a laminate foamed sheet is a method for producing a laminate foamed sheet to obtain a laminate foamed sheet by laminating a resin film on a polystyrene resin foamed sheet which is obtained by extrude foaming a resin composition, wherein the resin composition has a polystyrene resin and a polyphenylene ether resin, and also contains the polyphenylene ether resin of 10-50 pts.mass for the total 100 pts.mass of the polystyrene resin and the polyphenylene ether resin, and a polystyrene resin film, which has a polystyrene resin and a polyphenylene ether resin and has a softening temperature higher than the resin composition, is used as the resin film. <P>COPYRIGHT: (C)2013,JPO&INPIT |
