Abstract
A resin composition contains an ethylene-vinyl alcohol copolymer, wherein the ratio (Y/Z) of a lactone ring content (Y) to the sum (Z) of a carboxylic acid content (X) and the lactone ring content (Y) in terminal structures of the ethylene-vinyl alcohol copolymer is not less than 55 mol %, and at least one of a cinnamic acid component, a lubricant, a boron compound, and a conjugated polyene compound is present as a thermally stabilizing substance in a predetermined proportion based on the weight of the resin composition. Therefore, the resin composition is excellent in high-temperature thermal decomposition suppressing effect and thermal stability, and is free from odor emanation and coloration even if being processed at a higher temperature.
