- a conductive layer is laminated between the support layer and the thermoplastic innermost layer so that the heat generated by the induction heating is transferred to the innermost layer in the zone 5 to be heat-sealed by the high-frequency induction heating.
- a conductive layer is also laminated on both end portions 7 of the web-shaped laminated material in order to form a heat-sealing zone by high-frequency induction heating.
- FIG. 3 is a plan view showing a state where the final end of the laminated material 4 ′ from the first roll and the leading end of the laminated material 4 ′ from the second port are joined. Cutting is performed exactly in the middle between the sealing zone 5 of the laminated material 4 ′′ and the sealing zone 5 of the laminated material 4 ′.
- the distance A in Fig. 3 is the same as the distance A 'between the last end of the laminated material web 4''' on the downstream side of the printing process and the tip of the laminated material web 4 'on the upstream side of the printing process.
- the width of the conductive layer can be made wider than necessary to obtain the sealing property, so that there is room for absorbing the expansion and contraction of the paper. This bonding is performed accurately in a printing machine that is printing at high speed, using an automatic bonding machine, and can be mass-produced on large-scale flexographic and gravure printing machines.
- the front end of the upstream web-like support layer and the rear end of the downstream web-like support layer are joined to form a longer web-like support layer.
- the resulting web can be stored as a roll. Also, it can be continuously flowed to downstream processes without storage.
- the web prints the container design, indirectly or directly, on the outer surface of the web-like support layer in a printing process.
- indirect or direct means that a plastic laminate layer, a film layer, an adhesive layer, an anchor coat layer, and the like can be laminated between the printed layer of the picture and the design and the support layer surface.
- FIG. 4 is a schematic diagram of a packaging and filling machine used in the present invention.
- a laminated material of the present invention that is, a web-shaped laminated material comprising a support layer / a vapor-deposited film (metal-deposited layer / a substrate film) Z thermoplastic innermost layer is prepared.
- the rolled web-shaped laminated material 41 is loaded into a packaging and filling machine, the laminated material is pulled out from the roll 41, and transported into the filling machine.
- the web-like laminated material being conveyed is applied with a strip tape for vertical sealing by an applica- tion 42 and then formed into a tubular shape by a roller 144 while descending. It is sealed vertically in the longitudinal direction of the laminated material, and becomes liquid-tight without liquid leakage.
- a conductive layer is also laminated on one end 7 thereof.
- a conductive layer is also laminated on both ends 7 and 7 of the laminated material web in order to form a heat seal zone by high-frequency induction heating.
- the liquid food is filled into the laminated material tube from the filling pipe 45.
- a heat seal zone is formed at predetermined intervals by high-frequency induction heating, and the tube is horizontally sealed with a horizontal seal device (shown in FIG. 5).
- FIG. 5 is a schematic view of a horizontal sealing device of the filling machine.
- the packaging container in the present invention includes, for example, a hexagonal column, an octagonal column, a tetrahedron, a roof type container, etc., in addition to a prick shape (parallel hexahedron). As described above, according to the present invention, the following advantageous effects can be obtained.
- the present invention it is possible to form a seal / joint with a novel sealing method, and a large-scale flexographic printing press that is accurately processed using an automatic joining device in a printing press that is printing at high speed. It will be possible to perform mass production level with Daravia printing press.
- the method according to the invention makes it possible to apply a rapid and reliable sealing method to inexpensive packaging materials that do not contain any metal foil layers.
- the laminated material, the method for producing the laminated material, the method for heat-sealing the laminated material, and the packaging container according to the present invention are used for packaging containers for storing liquid foods such as milk and soft drinks.
