<P>PROBLEM TO BE SOLVED: To provide a heat sealing lid material which is used for a cup-type container in which beverage etc. is enclosed, and which is not peeled off even if it is heated by a warmer etc. at the time of sale, and on which the spigot member attached to the container is easily and tightly stuck, at the time of drinking, through the lid material, thereby warmed contents can be drunk safely. <P>SOLUTION: The heat-sealing lid material is constituted of a laminated film which has at least a non-oriented nylon film layer 1 excellent in elasticity and tear strength as a base body, on which a thermal adhesion resin layer 2 capable of being firmly thermally adhered to the container is laminated. Furthermore, it is possible that, on the outermost layer, a biaxially oriented polypropylene film layer is laminated, as is required, which is excellent in printability and which does not hinder the piercing of the spigot member, and a gas barrier layer is laminated for an intermediate layer. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
