Title:
OXYGEN-ABSORBING RESIN COMPOSITION AND OXYGEN-ABSORBING LAMINATE
Document Type and Number:
Japanese Patent JP2014198799
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an oxygen-absorbing resin composition and an oxygen-absorbing laminate, which have excellent oxygen-absorbing property and can be used suitably for forming a packaging material used for packing contents such as food, beverage, medicine, and the like which deteriorate in the presence of oxygen.SOLUTION: The oxygen-absorbing resin composition comprises an oxygen-absorbing resin comprising a cyclized conjugated diene polymer and a base resin comprising at least one thermoplastic resin selected from polyolefins and aliphatic polyamides, wherein a content of calcium stearate, as a content of calcium element derived from the calcium stearate, is 5 μg/g or less. The oxygen-absorbing laminate comprises an oxygen-absorbing layer comprising the oxygen-absorbing resin composition and a neighboring resin layer comprising a thermoplastic resin laminated on the oxygen-absorbing layer, wherein a content of calcium stearate of the neighboring resin layer, as a content of calcium element derived from the calcium stearate, is 20 μg/g or less.
