<p>Disclosed herein is a resin composition which comprises (A) an ethylene-vinyl alcohol copolymer having an ethylene content of 20-70 mol%, (B) a polyamide resin, and (C) a hydrophobic plasticizer which satisfies the condition specified by equation (1) below, with the amounts of components (A), (B), and (C) being 55-97 parts by weight, 3-45 parts by weight, and 0.1-30 parts by weight, respectively, on the basis of 100 parts by weight of the total amount of components (A) and (B). <MATH> where CH(A) denotes the ethylene content (mol%) in the ethylene-vinyl alcohol copolymer as component (A), and SP(C) denotes the solubility parameter of the hydrophobic plasticizer as component (C), which is calculated from Fedors equation. The resin composition can be formed into film or sheet superior in gas barrier properties readily by heat stretching without cracking and local thickness variation.</p> |
