A resin composition comprising: a polyolefin (A); a saponified ethylene-vinyl acetate copolymer (B) having an ethylene content of 20 to 65 mol% and having a degree of saponification of vinyl acetate units of 96% or more; a higher fatty acid metal salt (C) having 8 to 22 carbon atoms; and a conjugated polyene compound (D) having a boiling point of 20°C or higher; wherein the mass ratio (A : B) of the polyolefin (A) and the saponified ethylene-vinyl acetate copolymer (B) is 60 : 40 to 99.9 : 0.1, the amount of the higher fatty acid metal salts (C) is in the range of 0.0001 to 10 parts by mass per 100 parts by mass of the total of the polyolefin (A) and the saponified ethylene-vinyl acetate copolymer (B), and the amount of conjugated polyene compound (D) is in the range of 0.000001 to 1 part by mass per 100 parts by mass of the total of the polyolefin (A) and the saponified ethylene-vinyl acetate copolymer (B). This enables suppression of formation of aggregations at a micro-scale level, which serves to improve the dispersibility of EVOH. As a result, the occurrence of poor appearance such as wavy patterns on the molded article surface caused by flow anomalies due to the aggregates is suppressed, and thus, it is possible to obtain molded articles with good appearance. |
