PROBLEM TO BE SOLVED: To provide an ethylene-vinyl alcohol copolymer composition having excellent heat drawability, less occurrence of cracks and local thickness deviation during heat draw operation, and excellent gas barrier properties. . SOLUTION: It comprises an ethylene-vinyl alcohol copolymer (A) having an ethylene content of 20 to 70 mol%, a polyamide resin (B), and a hydrophobic plasticizer (C) satisfying the following formula (1). A resin composition containing 55 to 97 parts by weight of (A), 3 to 45 parts by weight of (B), and 0.1 to 30 parts by weight of (C) based on 100 parts by weight of the total of ()) and (B). 15 ≦ {CH (A)} 1/2 + SP (C) ≦ 22 (1) In the above formula (1), CH (A) is the ethylene content (mol%) of the ethylene-vinyl alcohol copolymer (A). ), And SP (C) indicates the solubility parameter (calculated from the Fedors equation) of the hydrophobic plasticizer (C). ｝ |
