1. method of making packing container with laminate wrapping material, this laminate wrapping material comprises thermoplastic material outermost layer, paper base material layer, thermoplastic material innermost layer, have first and second vertical side of the edge of mutual overlap joint formation packing container clinch, it is characterized in that:

  • A, the thermoplastic material outermost layer of described laminate wrapping material first vertical side of the edge is overlapped on the clinch that the thermoplastic material innermost layer of described second vertical side of the edge forms;

    B, heat this clinch, make the thermoplastic material outermost layer of first vertical side of the edge, the thermoplastic material innermost layer of second vertical side of the edge have viscosity;

    C, push this clinch, the thermoplastic material outermost layer sealing of first vertical side of the edge is sticked on the thermoplastic material innermost layer of this second vertical side of the edge;

    D, molten thermoplastic is extruded end at described first vertical side of the edge;

    E, extruding are also cooled off this molten thermoplastic formation band, make this band sealing stick on the end of this first vertical side of the edge.
