<p>PURPOSE:To obtain a good regrind by melt-kneading a reclaimable resin composition comprising a polyolefin, a saponified ethylene/vinyl acetate copolymer and a polyolefin modified with an unsaturated carboxylic acid under specified conditions. CONSTITUTION:A reclaimable resin composition (hereinbelow referred to as S) is kneaded with a polyolefin (APO-2) modified with an unsaturated carboxylic acid and having a melt index higher than that of the polyolefin in S under the conditions satisfying the formula wherein b is the fraction (pt.wt.) of APO-2 separately added to 100 pts.wt. S; B is the concentration (ppm) of the unsaturated carboxylic acid in APO-2; e is the fraction (wt.%) of the saponified ethylene/ vinyl acetate copolymer (EVOH) in S; alpha is the ethylene content (mol%) of EVOH in S; a is the fraction (wt.%) of a polyolefin (APO-1) modified with an unsaturated carboxylic acid in S; and A is the concentration (ppm) of the unsaturated carboxylic acid in APO-1.</p> |
