<P>PROBLEM TO BE SOLVED: To provide a laminated material, its manufacturing method, its heat seal method and a packaging container, by which a packaging system, even if different such as an aseptic packaging and a chilled packaging, is partly converted or used to enable an effective operation of the packaging system on the whole, furthermore to reduce energy and resources, and to contribute to the reduction of manufacturing cost. <P>SOLUTION: The laminated material is a web like laminated material for a packaging container comprising a supporting layer 1 and a thermoplastic inner most layer 3. The laminated material has a conductive layer 2 laminated between the supporting layer 1 and the thermoplastic inner most layer 3 so as to transmit the heat generated by induction heating to an area to be heat-sealed by the high frequency induction heating, in which the conductive layer 2 is a thin film/forming layer comprising a metallic conductive material. <P>COPYRIGHT: (C)2004,JPO |
