OXYGEN-ABSORBING MULTI-LAYER BODY

摘要

PROBLEM TO BE SOLVED: To provide an oxygen-absorbing multi-layer body configured to be activated by irradiation of ionization radiation, capable of suppressing thermal shrinkage or thermofusion at activation treatment and maintaining excellent oxygen-absorbing property for an extended period.SOLUTION: An oxygen-absorbing multi-layer body includes at least two layers, obtained by laminating an isolation layer including a thermoplastic resin and an oxygen absorption layer made of an oxygen-absorbing resin composition including a readily oxidizable thermoplastic resin and transition metal catalyst. The oxygen-absorbing multi-layer body initiates oxygen absorption by irradiation of a γ ray and/or an electron ray with dosage of 1-200 kGy.
