Description

Technical Field

[0001] This application relates to the field of identification card technology, and more particularly to an identification card. Background Technology

[0002] With the development of identification cards, people's demand for exquisite appearance and personalization of identification cards is increasing, leading to the development of identification card products with colored PVC (polyvinyl chloride) as the main structure. In addition to PVC identification cards in conventional colors, identification card products with a metallic texture have also emerged, such as metallic silver, metallic gold, and metallic red, which not only enhance the texture and aesthetics of identification cards but also provide cardholders with more personalized choices.

[0003] However, existing metallic identification cards have the following shortcomings:

[0004] 1) The metallic color layer has weak adhesion to the card body and is easily peeled off.

[0005] 2) The metallic color layer is not wear-resistant and is easily worn off due to friction during use.

[0006] 3) Metallic color layers mostly use aluminum foil. Due to the limited wear resistance of aluminum foil, there are few types of metallic colors to choose from, usually only gold and silver. Other metallic colors are not very applicable due to their poor wear resistance.

[0007] These issues affect the durability and aesthetics of the identification cards, thus reducing the user experience. Utility Model Content

[0008] The purpose of this application is to provide an identification card that can effectively optimize the adhesion of the metallic aluminum foil layer to the card body, enhance the firmness between the metallic aluminum foil layer and the card body, and significantly improve the wear resistance of the metallic aluminum foil layer; it also enriches the variety of metallic colors, no longer limited to the wear resistance of electroplated aluminum materials, and can be used for various metallic colors.

[0009] To achieve the above objectives, this application provides an identification card, comprising: a card body; wherein, from top to bottom, the card body includes a chip module, a front PVC film, a front PVC printed core layer, a middle material layer, a back PVC printed core layer, and a back PVC film; the four sides of the card body are provided with side structures, the side structures including: a first varnish layer, a metallic aluminum foil layer, and a second varnish layer stacked sequentially from the inside out, the first varnish layer using UV reversible varnish, and the second varnish layer using UV irreversible varnish.

[0013] As mentioned above, the UV curing energy of the LED cold light is 8 joules / cm². 2 Up to 10 joules / cm 2 .

[0014] As shown above, the thickness of the first varnish layer ranges from 0.02 mm to 0.05 mm.

[0015] As shown above, the thickness of the metallic aluminum foil layer ranges from 12um to 16um.

[0016] As shown above, the thickness of the second varnish layer ranges from 0.02 mm to 0.05 mm.

[0017] As shown above, UV inkjet printing is used to spray irreversible UV varnish onto a metallic aluminum foil layer. After curing with a UV lamp, a second varnish layer is formed on the outside of the metallic aluminum foil layer.

[0018] As described above, a heated circular silicone mold is used to roll the metal aluminum foil material onto the side of the card body that has been provided with the first varnish layer, forming a metallic aluminum foil layer.

[0030] As one embodiment, the specific implementation steps of the identification card in this application are as follows:

[0031] Step 1: First, the card body 1 (i.e., card base) of this application's identification card is manufactured according to the normal identification card production process. The card body, from top to bottom, includes a chip module, a front PVC film, a front PVC printed core layer, a middle material layer, a back PVC printed core layer, and a back PVC film.

[0032] Specifically, after completing step 1, you will get an identification card product with white sides, rather than a metallic color.

[0033] Furthermore, the card base material can be selected according to actual needs. In this application, white PVC material is preferred as the card base material.

[0034] Furthermore, the specific dimensions of the card body are set according to actual needs. In this application, it is preferred that the specifications of the identification card conform to the ISO7810 standard, the width of the card body is 53.92mm~54.03mm, and the length of the card body is 85.47mm~85.72mm.

[0035] Step 2: Spray an adhesive varnish onto the side of the card body to form the first varnish layer.

[0036] Specifically, after completing step 2, you will obtain an identification card product with the side coated with varnish, and at this time the varnish is in a cured state.

[0037] Furthermore, the varnish used in the first varnish layer is selected according to the actual situation. In this application, a UV (ultraviolet) reversible varnish is preferred. After being cured by LED (light-emitting diode) cold light, the UV reversible varnish can be softened by low-temperature heating.

[0038] The adhesive varnish used in this application is not limited to a certain type. As long as the varnish has similar performance and can be verified to improve the adhesion between the aluminum foil and the card body, it can be used. In this application, the preferred varnish is Molega UVS-886.

[0039] Furthermore, a UV inkjet printing method is used to spray UV reversible varnish onto the card body, and after being cured by LED cold light, a first varnish layer is formed on all four sides of the card body.

[0040] Specifically, this application employs UV inkjet printing, which allows multiple cards to be placed closely side-by-side and printed simultaneously. Adhesive varnish is applied to the sides of the cards, and after LED cold light curing, a first varnish layer is formed on all four sides of the card. The varnish application method used in this application is not limited to UV inkjet printing; any other printing method that can achieve a preset varnish thickness and uniform thickness is also acceptable.

[0041] Furthermore, the specific thickness of the first varnish layer is set according to actual needs. In this application, it is preferred that the thickness of the first varnish layer ranges from 0.02 mm to 0.05 mm.

[0042] Specifically, the preferred printing thickness of the varnish in this application is 0.02mm to 0.05mm.

[0043] Furthermore, the specific thickness of the first varnish layer is selected based on the flatness of the card body side, and in this application, it is preferably 0.03 mm.

[0044] Furthermore, the specific value of the UV curing energy for LED cold light is selected according to the actual situation; in this application, it is preferably 8 joules / cm². 2 Up to 10 joules / cm 2 .

[0045] Step 3: Hot stamp metal aluminum foil material on the outside of the first varnish layer to form a metallic aluminum foil layer.

[0046] Specifically, step 3 described in this application is not the only method for hot stamping aluminum foil material; any other method that allows the aluminum foil material to adhere well to the side of the card body can be implemented. After completing step 3, the production of the metallic identification card is actually completed, resulting in an identification card product with the aluminum foil material hot stamped on the side.

[0047] Furthermore, such as Figure 3 As shown, the specific implementation method for hot stamping metallic aluminum foil material on the outside of the first varnish layer to form a metallic aluminum foil layer is as follows:

[0048] T1: Secure the card body that has been fitted with the first layer of varnish.

[0049] T2: The metallic aluminum foil material is rolled onto the side of the card body, which has been provided with the first varnish layer, through a heated circular silicone mold to form a metallic aluminum foil layer.

[0050] T3: The heat from the circular silicone mold is conducted to the side where the first varnish layer has been applied, softening the cured first varnish layer. The metallic aluminum foil layer rolled onto the side of the card body can then adhere to the side of the card body.

[0051] Specifically, the heat from the circular silicone mold is conducted to the side where the first varnish layer has been applied, softening the cured UV reversible varnish, allowing the aluminum foil material rolled onto the side of the card body to adhere to the side of the card body.

[0052] T4: Aluminum foil can be attached to all four sides of the card body according to steps T1-T3, forming a metallic aluminum foil layer on all four sides of the card body.

[0053] Furthermore, the specific thickness of the metallic aluminum foil layer is set according to actual needs. In this application, it is preferred that the thickness of the metallic aluminum foil layer ranges from 12um to 16um.

[0054] Specifically, the thicker the metallic aluminum foil layer, the stronger its wear resistance.

[0055] Furthermore, the metallic aluminum foil material used for the metallic aluminum foil layer is selected according to the actual situation; in this application, it is preferably a Shenzhen Aurora PC series model.

[0056] Furthermore, the surface temperature of the circular silicone mold is consistent with the hot stamping temperature of the aluminum foil material used.

[0057] Step 4: To enhance the wear resistance of the metallic color, spray another layer of surface wear-resistant varnish onto the metallic aluminum foil layer to form a second varnish layer.

[0058] Specifically, using UV inkjet printing, multiple cards with metallic aluminum foil layers are placed closely side by side and printed simultaneously. After the surface wear-resistant varnish is applied to the sides of the cards with metallic aluminum foil layers, it is cured by a UV lamp, so that all four sides of the cards with metallic aluminum foil layers are coated with surface wear-resistant varnish, forming a second varnish layer.

[0059] Furthermore, the surface wear-resistant varnish used for the second varnish layer is selected according to the actual situation. In this application, a UV irreversible varnish is preferred, which cannot be softened after UV curing.

[0060] Specifically, a UV inkjet printing method is used to spray irreversible UV varnish onto a metallic aluminum foil layer. After curing with a UV lamp, a second varnish layer is formed on the outside of the metallic aluminum foil layer.

[0061] Furthermore, the second varnish layer used in this application is preferably DSK210G-4, but not limited to DSK210G-4; other varnishes with similar performance that have been tested and verified can also be used.

[0062] Furthermore, the specific thickness of the second varnish layer is set according to actual needs. In this application, it is preferred that the thickness of the second varnish layer ranges from 0.02 mm to 0.05 mm.

[0063] Specifically, the printing thickness of the second varnish layer's surface abrasion-resistant varnish (i.e., UV irreversible varnish) ranges from 0.02mm to 0.05mm, and the thicker the surface abrasion-resistant varnish, the better the abrasion resistance.

[0064] The beneficial effects achieved by this application are as follows:

[0065] (1) The identification card of this application can effectively optimize the adhesion of the metallic aluminum foil layer to the card body, enhance the firmness between the metallic aluminum foil layer and the card body, and significantly improve the wear resistance of the metallic aluminum foil layer.

[0066] (2) The identification card of this application enriches the categories of metallic colors and is no longer limited to the wear resistance of electroplated aluminum materials. Various metallic colors can be applied.
