Abstract: A packaging bag 100 having a heat-sealed part at an end and thereby formed into a bag shape, wherein the heat-sealed part 110 has an oxygen absorption layer 10, a water-vapor absorption layer 20, and a barrier layer 30, and wherein the oxygen absorption layer 10 contains an oxygen-deficient cerium oxide 11.

Abstract: An oxygen absorptive film 10a of the present invention is an oxygen absorptive film provided with an oxygen absorption layer 2 and a skin layer 4 laminated on at least one surface of the oxygen absorption layer, wherein the oxygen absorption layer contains polyolefin and cerium oxide having oxygen deficiency, and wherein the skin layer contains an acyclic olefin-based polymer and a cyclic olefin-based polymer.

Abstract: The present invention relates to a laminate for use in a blister pack, and to a blister pack using the same. The purpose of the present invention is to provide a blister pack laminate which fully imparts formability for the formation of dome-shape pockets in the blister pack laminate and which prevents moisture, organic gas and inorganic gas from entering the absorption layer from the end surface of the laminate through the reinforcement layer and deactivating the absorption layer. A further purpose of the present invention is to provide a blister pack that uses said blister pack laminate. The present invention relates to a blister pack laminate which comprises a substrate layer 1, an aluminum foil layer 2, a reinforcement layer 3, a barrier film layer 4, and an absorption layer 5, in that order.

Abstract: The purpose of the present invention is to provide a laminate for use in blister packs which fully imparts the forming property that forming defects do not occur, or are not prone to occur, even when forming the pockets in a blister pack to a relatively great depth, and to provide a blister pack using this laminate. The present invention relates to a laminate for use in a blister pack, which comprises a substrate layer 1, an aluminum foil layer 2, a first reinforcement layer 3a, a second reinforcement layer 3b, and an absorption layer 4, in that order.

Abstract: The present invention provides a film which has non-adsorbing properties equivalent to those of an ethylene-vinyl alcohol copolymer film, and which does not undergo a dimensional change in a humid environment. A laminate for heat sealing according to the present invention provided with: a non-adsorbing layer containing an ethylene-vinyl alcohol copolymer and an acid-modified polyolefin, and a non-swelling layer laminated on the non-adsorbing layer and containing a polyolefin and/or an acid-modified polyolefin.
