Abstract

PURPOSE: To obtain a laminated sheet having a sufficient adhesivity as a meat packaging tray without using an adhesive, separable and recoverable, by laminating a styrene resin on a polyolefin in the same die.
CONSTITUTION: A resin composition comprising 100 parts by wt. of polystyrene and at least 5 parts by wt. of a styrene-butadiene block copolymer is extrusion laminated on polyethylene or an ethylene-olefin random copolymer in the same die. Preferably, the block copolymer comprises 10W70 wt.% of butadiene from the standpoint of transparency and its amount is at least 5 parts by wt. per 100 parts by wt. of the postyrene due to the adhesivity and impact resistance. Low-density polyethylene or ethylene-propylene random copolymer resin is preferred as the polyolefin because of slight deterioration of transparency in molding with hot plates.
