Zusammenfassung:A resin molding and a method of producing the same in which sterilizability thereof is secured and discoloration (yellowing) thereof is reduced even when the resin molding is radiation-irradiated under anaerobic conditions (deoxidation conditions), are provided.The radiation-irradiated and packaged resin molding, comprising that said resin molding is primarily packaged with a packaging material having oxygen permeability and then secondarily packaged with an oxygen impermeable packaging material together with a deoxidizer.Further the method of producing a radiation-irradiated and packaged resin molding, comprising a step of primarily packaging a resin molding before radiation irradiation with a packaging material having oxygen permeability, a step of subsequently secondarily packaging with an oxygen impermeable packaging material together with a deoxidizer, and then conducting radiation irradiation. It is preferable to comprise a step of opening the secondary packaging under the atmosphere, following said radiation irradiation step.
