Provided is a resin composition including a polyolefin (A), a saponified ethylene-vinyl acetate copolymer (EVOH) (B) having an ethylene content of 20-65 mol% and having vinyl acetate units with a degree of saponification of 96% or more, a C8-22 metal salt of a higher fatty acid (C), a conjugated polyene compound (D) having a boiling point of 20? or higher, an ethylene-vinyl acetate copolymer (E), and a saponified ethylene-vinyl acetate copolymer (F) having an ethylene content of 68-98 mol% and having vinyl acetate units with a degree of saponification of 20% or more, and wherein the mass ratio (A:B) of the polyolefin (A) and the EVOH (B) is 60:40-99.9:0.1. The resin composition contains 0.0001-10 parts by mass of the metal salt of a higher fatty acid (C), 0.000001-1 parts by mass of the conjugated polyene compound (D), and a total of 0.3 or more parts by mass of the ethylene-vinyl acetate copolymer (E) and the saponified ethylene-vinyl acetate copolymer (F) combined, per a total of 100 parts by mass of the polyolefin (A) and EVOH (B) combined. As a result, when melt-molding the resin composition comprising of the polyolefin (A) and the EVOH (B), defects in the appearance of the molded product that result from poor dispersion of the EVOH (B) can be improved. |
