Abstract

PURPOSE: To manufacture a multi-layer blow-molded article composed of a polyolefin layer, an intermediate layer, and a nylon resin layer, wherein the burr of the article can be reclaimed and reused without lowering the adhesivity and the impact strength of the article, by using a specific modified ethylene copolymer as the intermediate layer.
CONSTITUTION: A multi-layer blow-molded article composed of a polyolefin resin layer, a nylon resin layer, and an intermediate layer consisting of a modified ethylene copolymer obtained by grafting 0.01W1 wt% of maleic anhydride to a copolymer having a crystallinity of 2W30% and prepared by the copolymerization of ethylene with a ≥3C α-olefin (pref. propylene, butene-1, etc.). The amount of the reclaimed burr permissible to be mixed to the olefin resin layer is up to twice as much as the weight of the olefin resin, and the one to be mixed to the intermediate layer is less than 30% of the layer. The nylon resin may be replaced by an ethylene- vinyl acetate copolymer saponificate.
