| abstract |
A resin composition that contains an ethylene vinyl alcohol copolymer and a thermal stabilization component. At end structures of the ethylene vinyl alcohol copolymer, the lactone ring content ratio (Y/Z) with respect to the total (Z) of the carboxylic acid content (X) and the lactone ring content (Y) is at least 55 mol%. The resin composition also contains a specific proportion of cinnamates, a lubricant, a boron compound, and/or a conjugated polyene compound. The resin composition has excellent thermal stability, e.g., excellent thermal decomposition resistance, even at high temperatures, and does not discolor or generate odors, even when processed at high temperatures. |
