摘要：
A resin composition comprising a modified ethylene-vinyl alcohol copolymer (A) and an unmodified ethylene-vinyl alcohol copolymer (B), wherein the modified ethylene-vinyl alcohol copolymer (A) is represented by a following formula (I), contents (mol%) of a, b, and c based on the total monomer units satisfy following formulae (1) to (3), and a degree of saponification is not less than 80 mol%, thereby providing a resin composition that is excellent in a barrier property, impact resistance, and secondary processability and moreover excellent in productivity.
