ナーシール材。[Claims for Utility Model Registration] 1. A resealable layer mainly made of paperboard, a surface layer formed of a releasable resin that has releasability to the back side of the resealable layer, and a heat-adhesive resin layer. In the inner sealing material for sealing a container opening, the inner sealing material is made of a laminated material, in which the resealing layer is laminated such that the back surface of the resealing layer and the surface of the sealing layer are in contact with each other. It has a laminated structure in which the paperboard and the polypropylene resin layer forming the back layer of the resealing layer are adhered with a hot melt adhesive, and metal foil is laminated in the sealing layer. A unique inner seal material for sealing the mouth of containers. 2. For sealing the mouth of a container according to claim 1 of the utility model registration claim, in which a partial printing layer made of a resin having affinity with the polyolefin resin layer is formed on the peelable resin layer forming the surface layer of the sealing layer. Inner seal material.
