[PROBLEMS] To reduce coloration, fish eyes (gels and blisters), streaks and the like, to have excellent appearance, to have excellent long-run properties during melt molding, to have little coloration during recovery, and to excellent interlayer adhesion when formed into a laminate. To obtain a resin composition comprising an ethylene-vinyl alcohol copolymer. The MFR when heated at 220 ° C. shows a minimum value and a minimum value within 10 hours from the start of heating, and shows a maximum value (MFRmax) within 100 hours, and acetic acid (A) is 50 to 500 ppm. The alkali metal salt (B) is 50 to 500 ppm in terms of metal element, the alkaline earth metal salt (C) is 10 to 120 ppm in terms of metal element, the phosphate compound (D) is 10 to 200 ppm in terms of phosphate radical, and the boron compound (E) 50 to 2000 ppm in terms of boron element, 0.005 to 1 part by weight of higher fatty acid amide with respect to 100 parts by weight of ethylene-vinyl alcohol copolymer, 0.5 ≦ MFRmax / MFR0 (non-heated ) ≦ 45 is satisfied.
