Oxygen-absorbing resin composition and oxygen-absorbing container comprising the same
Abstract:
An oxygen-absorbing resin composition having excellent performance is provided which contains an oxygen-absorbing polyester and a polyolefin and has enhanced compatibility between the polymers to give an oxygen-absorbing layer inhibited from having a reduced cohesive force or an appearance failure such as roughness unevenness. The oxygen-absorbing resin composition is characterized by being obtained by melt-kneading the following ingredients (A) and (B) together with the following ingredient (C) as a compatibilizing agent. Ingredient (A): an oxygen-absorbing polyester; Ingredient (B): a polyolefin; and Ingredient (C): a copolymer of ethylene and a vinyl monomer having a hydroxy group or an ester bond, the copolymer having an ethylene proportion of 70-99 mol %.
