OXYGEN-ABSORBING BARRIER RESIN COMPOSITION, FILM COMPRISING THE SAME, MULTILAYER STRUCTURE, AND PACKAGING CONTAINER

摘要

[PROBLEMS] To provide: an oxygen-absorbing barrier resin composition which has excellent oxygen-barrier properties even under high-humidity conditions and can give a multilayer structure having excellent peel strength; an oxygen-absorbing barrier film comprising the oxygen-absorbing barrier resin composition; a multilayer structure including a layer comprising the oxygen-absorbing barrier film; and a packaging container comprising the multilayer structure. [MEANS FOR SOLVING PROBLEMS] The oxygen-absorbing barrier resin composition comprises a matrix comprising a resin (A) having an oxygen permeability of 100 cc/m²·day·atm or lower and, dispersed in the matrix, a resin (B) having an oxygen absorption rate of 0.001 cc/cm²·day or higher, wherein the resin (B) is in the form of rods in which the average of the maximum diameters of sections perpendicular to the lengthwise direction is 1.0 µm or smaller. The resin (B) preferably is a product of cyclization of a conjugated diene polymer, the cyclization product having a percentage decrease in unsaturated-bond amount of 10% or higher.
