Provided is a resin composition comprising (A) polyolefin, (B) ethylene-vinyl acetate copolymer saponification product having an ethylene content of 20 to 65 mol% and a vinyl acetate unit degree of saponification of 96% or greater, (C) a C8-22 higher fatty acid metal salt, and (D) a conjugated polyene compound having a boiling point of 20°C or higher. The mass ratio (A:B) of the polyolefin (A) and ethylene-vinyl acetate copolymer saponification product (B) is 60:40 to 99.9:0.1. The resin composition contains the higher fatty acid metal salt (C) within a range of 0.0001 to 10 parts by mass per total 100 parts by mass of polyolefin (A) + ethylene-vinyl acetate copolymer saponification product (B), and contains the conjugated polyene compound (D) within a range of 0.000001 to 1 part by mass per total 100 parts by mass of polyolefin (A) + ethylene-vinyl acetate copolymer saponification product (B). Thus, production of aggregate within a microregion is suppressed and EVOH dispersibility is improved. Moreover, appearance defects caused by the formation of a wave-like pattern on the molded product surface due to aggregate-associated fluidity anomalies, and the like, are suppressed and a molded product having a pleasing appearance is obtained. |
