Abstract: A method of manufacturing a light barrier paper packaging material and the light barrier paper package container with low cost, no need of an ink removing apparatus at reproduction step and easily recycle are provided. A light barrier paper packaging material which comprises the paper substrate and the laminate layers on the paper substrate comprises: the paper substrate having a clay coat layer applied to the paper substrate; a light barrier layer printed with black ink on the clay coat layer; cover-up layers printed with white color ink to the light barrier layer a plurality of times; an outside laminate layer of thermoplastic resin formed on the cover-up layer, and design printed to the outside laminate layer.

Abstract: Even if an aseptic packaging system and a chilled packaging system are installed, a part of the counter system is diverted, thereby enabling efficient operation of the whole packaging systems. Therefore, the energy and materials can be reduced, and the manufacturing cost is also reduced. A laminate material is a web-shaped material for a package container. The laminate material has a support layer (1) and a thermoplastic innermost layer (3). A conductive layer (2) is provided in the region to be heat-sealed by high-frequency induction heating between the support layer (1) and the thermoplastic innermost layer (3) so that the heat generated by the induction heating is conducted to the innermost layer. The conductive layer (2) is a metal vapor deposition layer (2) provided on a base film (9) of a vapor deposition film (8) and made of a metallic conductive material.

Abstract: In this laminated material, the method of producing the laminated material, the method of heat sealing the laminated material and the packaging container, running/using/operation of the whole packaging system are allowed efficient through diversion or transfer of parts of different packaging systems of aseptic packaging and chilled packaging and, further, they contribute to the saving of energy and materials and the reduction of production cost. The laminated material is a web-form laminated material for packaging containers comprising a support layer 1 and a thermoplastic innermost layer 3. A conductive layer 2 is laminated between the support layer 1 and the thermoplastic innermost layer 3 at zones where heat-sealing is conducted by high-frequency induction heating so that the heat generated by induction heating is conducted to the innermost layer, and the conductive layer 2 comprises a thin film/formed layer substantially comprising a metallic conductive material.
