Patent name Laminate, method of production of laminates, method of heat-sealing of laminates and packaging containers Patent applicants Tetra Valle Group and Finance Co., Ltd. Principal applicant Address Kikuchi Eisai, inventor of Puri, Switzerland (patent) No. 03816895.2 Date of application 2003.07.16 Approval date Approval notice No. 1668456 Date of approval announcement 2005.09.14 Instruction CD-ROM D0537 Main classification number B32B7/02 Classification number B32B7/02; B29C65/36; B65B51/10; B65B51/22;B65D65/ 40 Division Original Application No. 2002.7.19 JP 211182/2002; 2003.2.28 JP 53245/2003 Abstract A laminate for aseptic packaging and refrigerated packaging, even in different packaging systems The efficient operation/use/operation of the entire packaging system is achieved through the conversion or transfer of some parts of different packaging systems, so that energy and materials can be saved and the production cost can be reduced; a process for producing the laminated material; a heat sealing Laminate method; and a packaging container. Laminate is a roll laminate for packaging containers that includes a support layer (1) and a thermoplastic innermost layer (3). A conductive layer (2) is provided at a region between the support layer (1) and the thermoplastic innermost layer (3) by heat-frequency induction heating to form a container, so that the heat generated by the induction heating can be Pass to the innermost layer. The conductive layer (2) comprises a thin film/shaped layer of a metallic conductive material. Slaves 1. A roll laminate for a packaging container comprising at least a support layer and a thermoplastic innermost layer, wherein heat is applied by high frequency induction heating between the support layer and the thermoplastic innermost layer The conductive layer is laminated at the area where the container is formed so that heat generated by induction heating can be transferred to the innermost layer, and the conductive layer is a thin film/shaped layer mainly comprising a metal conductive material.
