ABSTRACT:
Disclosed is a resin composition comprised of (a) 5 to 95 weight % of a saponified ethylene/vinyl acetate copolymer, (b) 95 to 5 weight % of a polyamide resin in which the content (in .mu.-equivalent/g of the polymer) of the terminal amino group in the molecule is larger than the content (in .mu.-equivalent/g of the polymer) of the terminal carboxyl group in the molecule, and (c) 0.5 to 10 weight % of a modified polyolefin formed by grafting an unsaturated carboxylic acid, or an acid anhydride or salt thereof onto a polyolefin. The resin composition can be stably shaped for a long time by extrusion.
