Figure 2 is a diagram showing a state of processing the I C-tagged package. The IC tag label 2 is attached to the package substrate 1b, and the adhesive 4 is applied to the substrate film or sheet surface including the IC tag label. In general, when a sealant film is laminated on a base material, the base material is passed between impression cylinders composed of a metal roll 7 and a rubber roll 8, and the adhesive 4 is applied to the surface of the package base material 1b. Thereafter, a sealant film is supplied to form a laminated film through nip rolls (not shown). In the figure, 9 is an adhesive supply pan, and a solvent type, a hot-melt type adhesive, or the like is used for the adhesive 4, and the type is not particularly limited.

I can't. In particular, since the IC chips of the package substrate 1b that are continuously supplied are usually arranged at a certain position, it is obvious that the certain circumferential portion of the metal roll is damaged to the extent that it cannot be reused.
On the other hand, in the case of FIG. 2, since the silicon substrate is protected by the label base 2b, it is possible to avoid damaging the metal roll. This method is generally applicable when using a metal roll such as a gravure roll coat.
[0015]
Figure 4 is a diagram showing another state of processing the I C-tagged package. FIG. 4 shows the case of an extrusion coater (EC machine). When a molten polyethylene 13 or the like is applied to a base film or sheet, the package base 1b is supplied from the nip roll 14 side which is a rubber roll. Then, the molten polyethylene is extruded from the T die 16, and the integrated film of the base film and the molten polyethylene 13 is pressed against the chill roll 15 which is a metal roll and laminated. Also in this case, if the IC chip 5 of the mounted IC tag label 2 is mounted so as to face the chill roll 15 side, the chill roll is damaged. The same applies to the case of application of the AC agent as the previous step.

(Comparative example)
An antenna pattern was gravure-printed with a conductive ink on a polyethylene terephthalate (PET) film having a thickness of 12 μm (“E5100” manufactured by Toyobo Co., Ltd.) to prepare a printing substrate film.
Next, an IC tag label (manufactured by Motorola, product name: IC chip mounting label “BiStatix”) was attached to the antenna printing surface side using a label applicator so that the IC chip side faced the sealant surface side. Therefore, in this case, the antenna pattern and the antenna of the IC tag label are not directly connected to each other, and are electrostatically coupled via the IC tag label base material.
Next, using a single EC machine, an AC (anchor coat) agent (Takeda Pharmaceutical Co., Ltd., A3210 / A3075, solid content 5%) is applied to the IC tag label side, and after drying, the resin temperature is 320 ° C. Extruded PE (Mitsui Chemical Co., Ltd. “Mirason 16P”); Extrusion lamination was carried out with a PE film having a thickness of 40 μm (“SKL film” manufactured by Dainippon Resin Co., Ltd.) at an extrusion thickness of 20 μm.
The layer structure of the laminate film produced by the above process is different from the example in that the IC chip 5 of the IC tag label 2 faces the surface of the sealant film 3, but the other structures are the same. .
[0022]
Using the laminate films (packaging bodies) of Examples and Comparative Examples, 1000 bags of snack confectionery packaging materials were produced. After recording predetermined data on the non-contact IC tag 10 as a confirmation item, an information reading test was performed using a BiStatix reader “WAVE” manufactured by Motorola as a reading device. All 1000 bags could be read correctly, but in the comparative example, 48 of 1000 bags could not be read.
When the cause of the sample that could not be read was examined, it was confirmed that the IC chip was damaged or the antenna was dissolved by the AC (anchor coat liquid) solvent.
Moreover, in the case of the comparative example, it was recognized that the coating roller of AC agent and the chill roller of the EC machine were damaged, and in the case of the example, there was no damage.
[0023]
The present invention is not limited to a soft packaging material, but can be applied to a carton or the like in which paper-films are laminated, and does not exclude a box-shaped packaging body.
