Claims

[Scope of utility model registration request]

A top layer consisting of a paper layer made of paperboard or hole plug balls, a first core layer consisting of a wax layer, a second core layer consisting of paper or foamed plastic, and a polyolefin resin. a resealable layer having a bottom layer that is resistant to heat, an uppermost layer that is made of a synthetic resin that has a weak affinity for the polyolefin resin that makes up the bottom layer of the resealable layer, and a core that is made of aluminum foil. and a sealing layer having a bottom layer made of a glass or plastic bottle opening and a heat-sealable polyolefin resin, between the bottom layer of the reseal layer and the top layer of the seal layer. An inner seal material for sealing the mouth of a container has a laminated structure partially bonded with an adhesive layer formed in a spot shape, and the adhesive layer formed in a spot shape is the most adhesive layer in the reseal layer. An inner seal material for sealing the mouth of a container, characterized in that it is composed of a synthetic resin that has good affinity for the polyolefin resin constituting the lower layer. −
