Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
At present, counterfeit products are frequently forbidden in the market, and the counterfeit products can cause benefit loss to both manufacturers and consumers, so that anti-counterfeiting treatment is necessary for the products.
In the related technology, the outer package of the product can be prepared by utilizing the holographic paper, and after the outer package of the product is prepared, the anti-counterfeiting label can be pasted on the outer package of the product, so that the anti-counterfeiting function can be realized by utilizing the holographic paper outer package and the anti-counterfeiting label at the same time. The anti-counterfeiting label can be printed with an anti-counterfeiting code, and the anti-counterfeiting code can be a two-dimensional code, a bar code or a quantum cloud code.
The holographic paper has a specific holographic image, and the manufacturing cost is high, so that a common counterfeit merchant is difficult to bear the cost for preparing the product package by the holographic paper, and an outer package of a counterfeit product is generally not prepared by the holographic paper, so that a consumer can judge whether the product is a genuine product by observing whether the outer package of the product has the specific holographic image. On the other hand, each genuine product generally corresponds to a unique anti-counterfeiting code, so that after a consumer scans the anti-counterfeiting code on the outer package of the product, whether the product is a genuine product or not can be determined according to the scanning result.
However, in the related art, after the outer package of the product is produced, the anti-counterfeit label needs to be attached to the outer package of the product, which adds additional cost and process steps.

The substrate layer 40 has good tensile strength and impact strength, is not easy to deform when being impacted by external, and has good effect of keeping the holographic image on the substrate layer 40.
The holographic image layer 41 may be made of resin having a function of bearing a holographic image, the holographic image layer 41 can present a holographic image, and the holographic image is an image having a laser effect, a platinum relief effect, a crystal relief effect, or a cat eye effect, and may include at least one of characters, symbols, or patterns. The holographic image is usually prepared by using a holographic molding plate, wherein the holographic molding plate can be a special metal sheet formed by laser beam lithography, the surface of the holographic molding plate is provided with a plurality of concave-convex stripes which can form a grating, and the density of the concave-convex stripes can be 800-1500 lines per mm.
The anti-counterfeiting code array 42 comprises a plurality of anti-counterfeiting codes arranged in an array. Optionally, the anti-counterfeit code may be at least one of a bar code, a two-dimensional code, and a quantum cloud code, and the user may obtain a scanning result by scanning the anti-counterfeit code, and after obtaining the scanning result, the user may determine whether the product is a genuine product according to the scanning result.

As shown in fig. 2, fig. 2 is a schematic diagram of an anti-counterfeit code array according to an embodiment of the present application, where the anti-counterfeit code array 42 in fig. 2 includes an arrangement array of 3 rows and 3 columns, which includes 9 anti-counterfeit codes 21.
The adhesive layer 45 is located on the holographic image layer 41, the material of the adhesive layer 45 may be a hot melt adhesive, and the main raw material of the hot melt adhesive may be EVA (Ethylene-vinyl acetate copolymer, chinese). The adhesive layer 45 is temperature sensitive, softens and has a strong adhesive force to adhere to paper when the temperature exceeds the softening temperature of the adhesive layer, and cures when the temperature is below the softening temperature of the adhesive layer. Wherein the softening temperature of the adhesive layer may be 110 ° to 120 °.
The adhesive layer 45 is cured at normal temperature and does not have an adhesive effect. Therefore, the holographic film can be folded in a roll shape, the storage space is saved, and the transportation is convenient.

When the holographic paper is produced, the holographic image layer and the anti-counterfeiting codes on the holographic film are transferred to the paper, so that the holographic paper can display the holographic image and the anti-counterfeiting codes at the same time.
Referring to fig. 3, it shows a schematic structural diagram of a holographic film provided by the embodiment of the present application, on the basis of the above-mentioned embodiment, in the embodiment of the present application, one side of each anti-counterfeiting code close to the adhesive layer 45 is printed with an ink 43 capable of completely covering the anti-counterfeiting code, that is, the ink 43 is printed on one side of the holographic image layer 41 printed with the anti-counterfeiting code array 42.

The color of the ink 43 is not limited in the embodiments of the present application, and the anti-counterfeit code can be clearly presented on the ink 43 as a selection principle.

In the embodiment of the present application, the coating amount of the material in the material tank 16 is not limited, and may be set according to actual requirements.
And 102, stamping the holographic image on the transfer layer to obtain a holographic image layer.
In the following, the embodiments of the present application will briefly describe a technical process of imprinting a holographic image on a transfer layer to obtain a holographic image layer, where the technical process may include:
the transfer layer and the substrate layer are heat treated to soften the transfer layer, wherein the temperature of the heat treatment may be 170-. Then, the holographic molded plate is pressed on the transfer layer, so that the holographic molded plate is tightly attached to the softened transfer layer. And then, applying a molding pressure to the holographic molding plate, wherein the molding pressure can be 0.30-0.50 MPa, and the molding depth can be: 12-200 microns, thereby forming a grating on the transfer layer to obtain a holographic image layer, wherein the grating comprises a plurality of concave-convex stripes, and the density of the concave-convex stripes is the same as that of the holographic mould pressing plate.

Alternatively, the inkjet printer may be a UV (ultraviolet curing) inkjet printer, and the ink for printing the anti-counterfeit code is UV ink, which is dried by UV light.
And 104, coating an adhesive layer on the side of the holographic image layer far away from the substrate layer.
The substrate layer of the holographic film can be BOPP, PET or PVC film, and the printing ink on the films is easy to crack and drop, so that the information of the product printed on the holographic film drops, and the holographic film cannot be directly used for making the outer package of the product. Generally, a holographic image layer on a holographic film is transferred to paper to obtain holographic paper, and the holographic paper is used for product outer package.
To facilitate the production of holographic paper using holographic films, in embodiments of the present application, an adhesive layer is applied to the side of the holographic image layer remote from the substrate layer, which may be used to transfer the holographic image layer to paper. Fig. 8 is a schematic diagram of an adhesive layer coating apparatus with which an adhesive layer may be coated onto a holographic image layer in step 104. As shown in fig. 8, the adhesive layer coating apparatus may include a first roller 30, a second roller 31, a third roller 32, a fourth roller 33, a fifth roller 34, an adhesive layer roller 35, and an adhesive layer chute 36.
The first roller 30 is a feeding roller for providing a holographic image layer, and the fifth roller 34 is a receiving roller. The first roller 30 rotates in the same direction as the fifth roller 34, and one end of the film-shaped substrate layer to which the hologram image layer is attached may be wound around the first roller 30 and the other end may be wound around the fifth roller 34, and when the first roller 30 and the fifth roller 34 rotate, the hologram image layer may be moved from the first roller 30 to the fifth roller 34 as the substrate layer is transferred via the second roller 31, the third roller 32, and the fourth roller 33.
An adhesive layer roller 35 is arranged below the second roller 31, a part of the adhesive layer roller 35 is immersed in an adhesive layer trough 36, and the material in the adhesive layer trough 36 is the material of the adhesive layer. The adhesive layer roller 35 can be brought into contact with the hologram image layer while rotating, and at the same time, the adhesive layer roller 35 can pick up the material in the adhesive layer groove 36 while rotating, and coat the picked-up material in the adhesive layer groove 36 onto the hologram image layer. Wherein the adhesive layer tank 36 has a heating assembly disposed therein for heating the contents of the adhesive layer tank 36 to soften the contents of the adhesive layer tank 36 into a liquid. The heating temperature may be 110-120 deg.
The third roller 32 is provided therein with a heating unit for drying the material coated on the holographic image layer to form an adhesive layer.
The coating amount of the material in the adhesive layer tank 36 is not limited in the embodiment of the present application, and may be set according to actual requirements.
The holographic image is stamped on the substrate layer to form the holographic image layer, and the anti-counterfeiting code array is printed on the holographic image layer, so that the holographic film is provided with the holographic image layer and the anti-counterfeiting codes at the same time.
Referring to fig. 9, which shows a flowchart of a method for manufacturing a holographic film according to an embodiment of the present application, on the basis of the above-mentioned embodiment, before step 104, the method for manufacturing according to an embodiment of the present application further includes:
step 201, printing ink capable of completely covering the anti-counterfeiting codes on the side of each anti-counterfeiting code far away from the substrate layer.
As shown in fig. 10, where CDC denotes the substrate layer, QXC denotes the hologram image layer, FWC denotes the anti-counterfeiting code, C side denotes a side of the anti-counterfeiting code FWC away from the substrate layer CDC, and D side denotes a side of the anti-counterfeiting code FWC close to the substrate layer CDC.
Since the holographic image layer and the anti-counterfeit code on the holographic film need to be transferred to the paper when the holographic paper is prepared, the color of the paper may affect the definition of the anti-counterfeit code. For example, if the color of the security code is yellow and the color of the paper is also yellow, the security code appearing on the hologram paper is unclear because the color of the paper and the color of the security code match.
In order to ensure that the anti-counterfeiting code is clearly displayed, in the embodiment of the application, the ink covering the anti-counterfeiting code is printed on the anti-counterfeiting code, and the color of the ink is different from that of the anti-counterfeiting code.
In the following, the embodiment of the present application will briefly describe a technical process of printing ink that completely covers an anti-counterfeit code on a side of the anti-counterfeit code away from a substrate layer, where the technical process includes:
a printing form is obtained which may be a printing form that has been surface treated to transfer printing ink on one part and not on the other part. The part of the printing plate capable of transferring printing ink corresponds to the anti-counterfeiting code arrangement information on the holographic image layer. Then, the printing plate is installed on a printing machine, the holographic image layer is printed, and the ink is printed on the holographic image layer at the position corresponding to the anti-counterfeiting code by utilizing the part of the printing plate, which can transfer the printing ink.
The method for coating the adhesive layer on the side of the holographic image layer printed with the ink completely covering the anti-counterfeiting code is basically the same as the step 104, and is not described herein.
According to the embodiment of the application, the anti-counterfeiting code is printed with the ink capable of completely covering the anti-counterfeiting code, and the contrast between the color of the ink and the color of the anti-counterfeiting code is better. When the anti-counterfeiting code is displayed on the holographic paper, the anti-counterfeiting code is positioned above the printing ink, and the color of the anti-counterfeiting code is larger than that of the printing ink, so that the anti-counterfeiting code displayed on the holographic paper is clearer and has more vivid color, the observation and the scanning of a user are facilitated, and the use convenience is improved.
Referring to fig. 11, which shows a flowchart of a method for manufacturing a holographic film according to an embodiment of the present application, on the basis of the above-mentioned embodiment, before step 104, the method for manufacturing according to an embodiment of the present application further includes:
and 301, arranging a gloss layer on one side of the holographic image layer, which is far away from the substrate layer.
The material of the gloss layer can be aluminum or zinc sulfide, and the gloss layer has high brightness and can present metal gloss or matte. Optionally, the surface reflectivity of the gloss layer is greater than a reflectivity threshold, which may be 0.25. Optionally, the gloss layer may be an aluminum plated layer or a zinc sulfide plated layer.
Next, in this application embodiment, taking the material of the gloss layer as an example, briefly explaining the technical process that the gloss layer is arranged on the side of the holographic image layer away from the substrate layer, the technical process includes:
gasifying aluminum at 2500-; then, the substrate layer and the holographic image layer are placed on the mobile equipment in the vacuum chamber, the substrate layer is in contact with the mobile equipment, and the holographic image layer is located on one side, far away from the mobile equipment, of the substrate layer. The mobile equipment is used for bearing the lining and transmitting the substrate layer and the holographic image layer to move in the vacuum chamber, the cooling assembly is arranged on the mobile equipment and used for cooling the substrate layer and the holographic image layer so that the temperature of the substrate layer and the holographic image layer is lower than the gasification temperature of aluminum, and therefore gaseous aluminum can be attached to the surface of the holographic image layer and a layer of aluminum film, namely a gloss layer, is formed on the surface of the holographic image layer.
After the formation of the gloss layer in step 301, an adhesive layer is coated on the gloss layer in substantially the same manner as in step 104, which is not described herein again.
This application embodiment sets up the gloss layer through keeping away from one side of substrate layer at holographic image layer for the luminance of holographic membrane is high, and the luminance of the holographic image that the holographic paper that uses this kind of holographic membrane preparation appears is higher, can be convenient for the user to observe and distinguish the product true and false.

And 403, bonding the holographic film with the raw paper layer.
And after the bonding layer is softened, the raw paper layer is bonded with the holographic film through the bonding layer.
And after the base paper layer is bonded with the holographic film, the substrate layer is peeled from the holographic image layer, in the embodiment of the application, the adhesion force between the substrate layer and the holographic image layer is smaller than that between the base paper layer and the bonding layer, so that the holographic image layer and the anti-counterfeiting code, the ink covering the anti-counterfeiting code and the gloss layer printed on the holographic image layer can be remained on the base paper layer when the substrate layer is peeled from the holographic image layer.
In the embodiment of the application, the holographic film is provided with the holographic image layer and the anti-counterfeiting code at the same time, so that the holographic paper prepared by using the holographic film can present the holographic image and the anti-counterfeiting code at the same time. The outer package of the product prepared by the holographic paper does not need to be pasted with an anti-counterfeit label, so that compared with the prior art, the process of pasting the anti-counterfeit label is reduced, and the processing cost of the product is reduced.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
