Abstract
A stabilizer selected from alkaline earth metal hydroxides, oxides and silicates and alkaline earth metal salts of higher fatty acids and an antioxidant are incorporated into a resin composition comprising an ethylene/vinyl alcohol copolymer and a propylene resin or a carbonyl group-containing thermoplastic resin. The stability of the resin composition is improved, and deterioration of the resin composition such as gelation, discoloration or reduction of the gas barrier property is prevented when this composition is heat-molded into a vessel.
