Abstract

There is provided a resin composition, comprising an ethylene-vinyl alcohol copolymer and a nonionic surfactant, wherein the ethylene-vinyl alcohol copolymer has an ethylene unit content of 15 to 60 mol %, and a saponification degree of 90 mol % or more; the ethylene-vinyl alcohol copolymer is contained as a major component; and the nonionic surfactant is contained at 3 to 400 ppm. The resin composition is produced by melt-kneading a mixture comprising the nonionic surfactant, water and the ethylene-vinyl alcohol copolymer. By using the resin composition thus produced, a discharge amount during melt molding can be increased and a molded article with an excellent appearance can be provided.
