A method for producing a skin-covered foamed molded article includes blow molding a parison into a skin and heating expanded polystyrene beads filled in a hollow space of the skin to form a foam layer fuse-bonded to the skin, polystyrene resin composition having specific Charpy impact strength, MFR and branching degree. The skin of the skin-covered foamed molded article is formed of the specific polystyrene resin composition.
1. A method for producing a skin-covered foamed molded article, the method comprising the steps of: (a) providing a parison that is in a molten or softened state, the parison being formed of a polystyrene resin composition;(b) blow molding the parison into a skin defining a hollow interior space;(c) filling expanded polystyrene beads in the hollow interior space; and(d) heating the expanded polystyrene beads filled in the hollow interior space to fuse-bond the expanded polystyrene beads to each other and to form a foam layer fuse-bonded to the skin,where...
