Abstract:
Provided is a method for producing a skin-covered foamed molded article of a hollow molded article in which a molded article of foamed particles is included by forming a hollow molded article by blow molding a parison formed by extruding a melt kneaded product of a polyethylene-based resin, filling thermoplastic resin foamed particles within the hollow molded article, and fusion bonding the foamed particles by supplying and discharging a heating medium from a heating medium supply pins inserted into the hollow molded article, wherein a polyethylene-based resin composition having tensile elongation at break of 500 to 1000% at 80° C. and half-crystallization time of 5 to 50 seconds at 120° C. is used for forming the hollow molded article so that a skin-covered foamed molded article having excellent fusion bonding property between foamed particles can be obtained with a short molding cycle.
