Figure 3 is a view showing a card sheet to which the present invention is applied, Figure 4 is a view for explaining a hot press process to which the present invention is applied, Figure 5 is a view showing a thermal film coating sheet to which the present invention is applied, FIG. 6 is a view for explaining a thermal laminating process to which the present invention is applied, FIG. 7 is a view for explaining a card punching process to which the present invention is applied, and FIG. 8 is a diagram illustrating a hot stamping process to which the present invention is applied. It is a figure for following.

The thermal film coating card to which the present invention is applied is basically a thermal film coated on the card sheet 10, the card sheet 10 is a front protective film 11, the front printing paper 12, the core sheet 13, the back printing paper 14 and the back protection film 15. As shown in FIG.

The front printing paper 12 and the rear printing paper 14 are made of synthetic resin, and a basic card design is printed.

The front protective film 11 and the rear protective film 15 are made of a transparent material and serve to protect the printing surfaces of the front printing paper 12 and the rear printing paper 14 and expose them to the outside. In this case, a magnetic strip may be attached to the rear protective film 15.

The core sheet 13 is an inlay sheet that determines the thickness of the card.

At this time, it is possible to adjust the thickness of the entire card by adjusting the thickness of the core sheet 13, it is possible to comply with the thickness suitable for various card standards actually used. Therefore, the description of the exact thickness of the card is omitted.

The front protective film 11, the front printing paper 12, the core sheet 13, the back printing paper 14, and the rear protection film 15 are press-bonded at a proper temperature and press pressure in a temporarily bonded state. It is bonded by a hot press process, and the bonded card sheet 10 is coated with a thermal film 20 and passed through a roller engraved in an intaglio or embossed sheet to heat-emboss the thermal film 20.

Then, the embossed card sheet 10 is punched into sheets and each sheet card is individually embossed by a hot stamp process.

That is, the primary card design is performed by the printing surface of the front printing paper 12 and the rear printing paper 14 forming the initial card sheet 10, and the thermal film 20 of the card sheet 10 with respect to The secondary card design is performed by the sheet embossing process, and the tertiary card design is performed by the individual embossing process for the thermal film 20 of the single card.

Now with reference to Figures 3 to 8 look at in detail with respect to the method for manufacturing a thermal film coating card to which the present invention is applied.

Referring to FIG. 3, first, an adhesive glue solvent is used for the front protective film 11, the front printing paper 12, the core sheet 13, the back printing paper 14, and the back protection film 15. Is temporarily bonded.

And, as shown in Figure 4, through the laminator 110 with the heater rod 111 that dissipates heat therein is pressed by the appropriate heat and pressure from the upper and lower sides to form a card sheet 10.

At this time, the card sheet 10 laminated by the heat and pressure is hardened after the laminating work.

The thermal film 20 is seated on the completed card sheet 10 as shown in FIG. 5.

Here, although the adhesive layer 21 is preferably provided on the card sheet 10 side bonding surface of the thermal lamination film 20, the adhesive layer 21 may be formed when the adhesive component is included in the thermal lamination film 20 itself. Of course it is unnecessary.

At this time, the thermal lamination film 20 is made of a transparent material, it is a laminating film that is free from residual harmful substances because it is fused to the surface of the adherend itself, the upper protective layer and the inner filling layer and the lower thermal adhesive layer It can be configured to display images with high transparency during high pressure heat welding.

The thermal film 20 may be seated on the upper surface of the card sheet 10 as well as the lower surface, and in the following description and reference drawings, the thermal film 20 on the upper surface of the card sheet 10 for convenience of description. ) Is seated and shows the process of embossing.

That is, as shown in FIG. 6, the card sheet 10 and the thermal lamination film 20 are inserted together into the heating roller devices 120 and 130 to be thermally laminated.

At this time, a predetermined design is engraved in an intaglio or embossed in the upper engraving roller 120 constituting the heating roller device, the heater rod 121 is embedded therein. And the lower pressure roller 130 is in close contact with the engraving roller 120 to press the card sheet 10 and the thermal film 20 is strongly pushed in.

Here, the engraving roller 120 is the overall card design is formed, because the overall pattern is formed on the engraving surface of the embossed or intaglio so that when the secondary card embossing design, the thermal film 20 is expressed as matt do.

Accordingly, the card sheet 10 and the thermal film 20 are thermally coated by high temperature and strong pressure, and at the same time, the thermal film 20 is applied to the engraved or embossed design of the engraving roller 120. This results in an embossed design.

In general, since the thermal lamination film 20 was developed for the purpose of coating on paper, a stronger thickness and a higher temperature are required when the card is thicker and stronger than the paper.

Therefore, the material of the pressure roller 130 is preferably composed of a metal of high strength.

In addition, the temperature and pressure conditions of the heating roller device (120, 130) used for this secondary embossing design process is as follows.

First, a warpage phenomenon occurs in the card sheet 10 under a press temperature of 150 ° C. or higher, which is inappropriate. In addition, under a press temperature of 100 ° C. or less, the adhesive strength of the card sheet 10 and the thermal film 20 is weakened, and the pattern engraved on the engraving roller 120 is not accurately represented, which is inappropriate. Therefore, the temperature conditions of the heating roller apparatuses 120 and 130 used for the secondary embossing design process are preferably determined between 150 degreeC and 100 degreeC, Most preferably, it is a press temperature of 120 degreeC.

Next, under the press pressure of 0.5 bar or less, the adhesive strength of the card sheet 10 and the thermal film 20 is weak, and the defect which falls falls occurs. In addition, under press pressure of 0.8 bar or more, the embossed patterns of the intaglio and embossed solidify strongly, and the subsequent third embossing design processing is impossible. Therefore, the pressure conditions of the heating roller apparatuses 120 and 130 used for the secondary embossing design process are preferably determined between 0.5 bar and 0.8 bar, and most preferably the press pressure of 0.6 bar.

At this time, as described above, when the thermal lamina film 20 is coated on the card sheet 10 on both sides, a corresponding engraved or embossed design is also carved on the corresponding pressure roller 130, and a heater rod may be built in. It is also possible to form a double sided embossing design in two phases, the coating process and the backside coating process.

Thereafter, the card sheet 10 on which the secondary card design is completed by the sheet embossing process on the thermal film 20 of the card sheet 10 is cut into individual sheet cards. That is, as illustrated in FIG. 7, the card sheet 10 inserted into the punching die 140 is separated into a single card 30.

Then, as shown in FIG. 8, the single card 30 is stamped by a stamp 150 having a engraving surface in which the design to be emphasized is carved. At this time, since the sheet card 30 is pressed by the stamp 150 having a constant pressure and temperature in the stamping process, the embossed design is formed by the intaglio or embossed design of the engraving surface.

Here, the secondary card design formed by the sheet embossing treatment on the thermal film 20 of the card sheet 10, and the tertiary card design formed by the individual embossing treatment on the thermal film 20 of the sheet card. Has the following differences:

In the secondary card design, the thermal film 20 is subjected to the entire matte embossing process by the engraving rollers 120 of the heating roller devices 120 and 130, and in the third card design, the thermal film 20 is hot. Since the design portion to be emphasized of the stamp 150 is formed by a flat engraving surface, it is pressed as if ironed by the engraving surface, so that the pattern is spread and is expressed as an intaglio gloss.

Therefore, in this case, the overall design of the second embossing process using the heating roller device is that the entire matte design is formed on the thermal film 20 in an intaglio or embossed form, and in the third embossing process using the hot stamp 150. The accentuating design is engraved and formed on the thermal film 20 in a gloss manner.

However, such intaglio or embossed and glossy or matte design expressions can be easily modified by deforming the engraving form of the heating roller device and the engraving form of the hot stamp.

Although the card using the magnetic strip is exemplified in the above-described embodiment as the information recording medium, a smart card or the like may also be used as the information storage medium.

Therefore, the thermal film coating card of the present invention that can be configured as a simple manufacturing process compared to the flat printed matter used in the existing card, and can be shipped as a three-dimensional and lively advanced card, while satisfying the international standards It has no impact on physical and electrical properties, so it can be immediately applied to the production of contact IC cards, R / F cards, and Combi cards, which are activated in the future.
