To provide polystyrene-based resin compositions having excellent workability when laminating a film onto a polystyrene-based-resin foam sheet, and resistant to the elution of styrene dimer or styrene trimer into the soup of precooked noodles when laminating the film inside the container of the precooked noodles, or the like, made of the polystyrene-based-resin foam sheet, a laminated foam sheet, and a container formed of this sheet.
This resin composition of the laminated-film is formed by adding a phenol-based oxidation inhibitor and/or a phosphorus-based working stabilizer into a compound of polystyrene-based resin and styrene-based rubber, and the laminated foam sheet and the container made of this sheet are formed by laminating the laminated-film with 20 or more times elongation of fusion at rupture at 250°C in the resin composition of the laminated-film, over the foamed sheet of polystyrene-based resin.
