Abstract:
PROBLEM TO BE SOLVED: To provide a polystyrene-based resin composition suitable for forming a foamed molded article such as a polystyrene-based resin foamed sheet while utilizing a remnant such as a trimming loss or the like as a recycling raw material, and to provide a laminate sheet and a packaging vessel each capable of satisfying a requirement for reducing consumption of resources.SOLUTION: The provided laminate sheet is obtained by laminating a polyolefin-based resin film on at least one surface of the polystyrene-based resin foamed sheet. The provided molded article is obtained by thermoforming the laminate sheet. The provided polystyrene-based resin composition contains the recycling raw material composed of one or more of the remnants remaining after removing the molded article from the thermoformed laminate sheet, and further contains a compatibilizer composed of either one or both of a styrene-ethylene/butylene-styrene block copolymer and a styrene-ethylene/propylene-styrene block copolymer.
