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 packing container comprising the multilayer structure. [MEANS FOR SOLVING PROBLEMS] The oxygen-absorbing barrier resin composition comprises a resin (A) having an oxygen permeability of at most 100 cc/m 2 ·day·atm and a resin (B) having an oxygen absorption rate of at least 0.001 cc/cm 2 ·day, wherein the resin (B) is dispersed in the matrix of the resin (A) and the resin (B) is in the form of rods in which the average of the maximum diameters of cross sections perpendicular to the lengthwise direction is at most 1.0 µm. The resin (B) preferably is a product of cyclization of a conjugated diene polymer, the cyclization product having an unsaturated bond reduction ratio of at least 10 %.
