Beschreibung
Zusammenfassung:	A polyolefin resin composition comprising (A) 50 to 99.5 weight % of a polyolefin resin, (B) 0.4 to 50 weight % of a saponified ethylenevinyl acetate copolymer, and (C) 0.1 to 15 weight % of a graft polymer obtainable by grafting an ethylenically unsaturated carboxylic acid or a derivative thereof to a polyolefin resin and reacting the adduct with a polyamide, which composition satisfies the relation: M2/M1 = not less than 1.5 wherein M2 and M1 are the melt flow rates of (B) and (A), respectively, under a load of 2160 g at 210 C. The present invention is predicated on the above finding. r
