PROBLEM TO BE SOLVED: To provide an oxygen-absorbable PTP package which is produced by using a novel oxygen-absorbable multi-layer body as a bottom material of the oxygen-absorbable PTP package, suppresses production of an odor after absorbing oxygen without using any material that responds to a metal detector, and has excellent oxygen-absorbing property.SOLUTION: The oxygen-absorbable PTP package includes: an oxygen-absorbable bottom material produced by molding the oxygen-absorbable multilayer body composed of at least three layers produced by laminating a sealant layer containing a thermoplastic resin, an oxygen-absorbable layer composed of an oxygen-absorbable resin composition containing a copolymerized polyolefin compound and a transition metal catalyst, and a gas barrier layer containing a gas barrier substance in this order; and a gas barrier lid material composed of at least two layers produced by laminating an inner layer containing a thermoplastic resin, and a gas barrier layer containing a gas barrier substance in this order. The sealant layer of the oxygen-absorbable bottom material and the inner layer of the gas barrier lid material are bonded, and the copolymerized polyolefin compound contains a structural unit having at least one tetralin ring. |
