OXYGEN-ABSORPTIVE PTP PACKAGING BODY

摘要

PROBLEM TO BE SOLVED: To provide an oxygen-absorptive PTP packaging body the bottom material of which is formed from a new oxygen-absorptive multilayer body that suppresses emission of a bad smell after absorbing oxygen and has excellent oxygen absorption performance.SOLUTION: The oxygen-absorptive PTP packaging body includes: an oxygen-absorptive bottom material which is obtained by molding an oxygen-absorptive multilayer body that has an oxygen absorption layer containing an oxygen-absorptive composition and a thermoplastic resin layer containing a thermoplastic resin and comprises at least two layers; and a lid material having gas barrier properties, which material is obtained by layering an inner layer containing a thermoplastic resin and a gas barrier layer containing a substance having gas barrier properties in this order and comprises at least two layers. The oxygen-absorptive PTP packaging body is obtained by joining the thermoplastic resin layer of the oxygen-absorptive bottom material to the inner layer of the lid material having gas barrier properties. The oxygen-absorptive composition contains at least one compound having a tetralin ring of a specific structure, a transition metal catalyst, and a thermoplastic resin.
