Description

Technical Field

[0001] The present application relates to the technical field of anti-counterfeiting packaging paper production, and in particular to a laser holographic packaging material for reproducing an anti-counterfeiting code using a light source. Background Art

[0002] Aluminized paper has been widely used in the packaging field due to its noble and beautiful metallic texture as well as its biodegradable and recyclable environmentally friendly properties.

[0003] QR code technology is widely used in the packaging of various foods and daily chemical products. The current QR code has integrated the function of multiple codes into one. Consumers can scan the QR code to prevent counterfeiting and trace the source or participate in the merchant's activities to win points. Merchants can also use the QR code to understand the sales channel of the product and control the distributors, such as monitoring which channel has price-breaking behavior and affecting the brand's pricing.

[0004] Currently, most QR codes are printed on the visible surface of packaging boxes and bags. This printing method has the following problems: First, in terms of the functionality of the points lottery, there is a high possibility that the QR code will be stolen and scanned before the product is sold, causing the consumer to lose their due rights; second, the printing of QR codes will reduce the overall beauty and appearance of the product to a certain extent, affecting consumer choices; third, even if the external QR code uses scratch-resistant ink varnish, some dealers can still use a scraper to erase the barcode and QR code, affecting the merchant's control over the channel.

[0005] There are many solutions to the above problems on the market, such as printing the QR code separately and then splicing it together, but it is easy for the splicing seam to be too large to be scanned; designing covers and inserts or tearable structures to hide and protect the QR code labels, but they all require additional materials to carry out this special box-making process; or printing the QR code on the inside of the package, but this method does not have a process barrier and is easily copied and imitated by unscrupulous merchants. Utility Model Content

[0006] In order to provide an anti-counterfeiting code packaging paper that is easier to produce and has lower cost, the present application provides a laser holographic packaging material that reproduces the anti-counterfeiting code with a light source.

[0007] The laser holographic packaging material for reproducing anti-counterfeiting codes by light source provided in the present application adopts the following technical solution:

[0008] A laser holographic packaging material for reproducing anti-counterfeiting codes with a light source comprises: a base paper layer on which a hidden two-dimensional code printing layer is printed; an aluminized layer comprising laser information, the aluminized layer being arranged on one side of the base paper layer on which the hidden two-dimensional code printing layer is arranged.

[0009] By adopting the above technical solution, using a hidden QR code printing layer arranged on the side of the base paper layer close to the aluminum-plated layer, the anti-counterfeiting packaging paper can be illuminated by a light source from behind, and the anti-counterfeiting QR code printed on the base paper layer can be clearly observed through the aluminum-plated layer. This can achieve the effect of hiding the QR code without adding too much raw materials, affecting the aesthetics of the packaging, or changing the existing packaging design, thereby improving the technological barriers and anti-counterfeiting strength of the packaging.

[0010] Preferably, a first two-dimensional code printing layer is printed on a side of the base paper layer away from the aluminum-plated layer.

[0011] By adopting the above technical solution, the first two-dimensional code printing layer can be used to facilitate users to scan.

[0012] Preferably, a second two-dimensional code printing layer is printed on a side of the aluminum-plated layer away from the base paper layer.

[0013] By adopting the above technical solution and utilizing the second QR code printing layer, consumers can more conveniently scan the QR codes on both sides of the packaging paper, further improving the portability of scanning the QR code.

[0014] Preferably, a wet composite adhesive layer is provided between the base paper layer and the aluminum-plated layer.

[0015] By adopting the above technical scheme, the flexible printed layer and the aluminum-plated layer are wet-compounded with the help of a wet composite adhesive layer. The composite process is simple to operate and uses less adhesive, which helps to save corporate costs. At the same time, the wet composite process has a fast composite rate, which helps to improve the production efficiency of anti-counterfeiting packaging paper.

[0016] Preferably, the wet composite adhesive layer is formed by coating a water-based environmentally friendly composite adhesive on the aluminum-plated layer.

[0017] By adopting the above technical solution and using the water-based environmentally friendly composite adhesive layer for wet composite process, it is beneficial to the green and environmentally friendly production process of anti-counterfeiting packaging paper.

[0018] As a preference, the base paper layer can be selected from 80g / m 2 Up to 350g / m 2 .

[0019] By adopting the above technical solution, at 80g / m 2 Up to 350g / m 2 Within the range, the strength and thickness of the base paper layer are guaranteed to meet different packaging requirements.

[0020] Preferably, the aluminum coating layer can be configured as a transfer aluminum coating layer or a PET aluminum coating layer.

[0021] By adopting the above technical solution, the scope of use is expanded, so that this embodiment can be used in transferring aluminized paper or PET aluminized paper.

[0022] Preferably, the aluminum plating thickness of the aluminum plating layer is 300 to 360Å.

[0023] By adopting the above technical solution, the aluminum plating layer with nanometer thickness can be easily degraded and is more environmentally friendly.

[0024] To summarize, the present application includes at least one of the following beneficial technical effects: by arranging a QR code printing layer on the side of the base paper layer close to the aluminum-plated layer, when the anti-counterfeiting packaging paper is illuminated by a light source from the back, the anti-counterfeiting QR code printed on the base paper layer can be clearly observed through the aluminum-plated layer, thereby achieving the effect of hiding the QR code without adding too much raw materials, affecting the aesthetics of the packaging, or changing the existing packaging design, thereby improving the technological barriers and anti-counterfeiting strength of the packaging.

[0027] The following is combined with Figure 1 This application is described in further detail.

[0028] The embodiment of the present application discloses a laser holographic packaging material that uses a light source to reproduce an anti-counterfeiting code.

[0029] Reference Figure 1 A laser holographic packaging material for reproducing anti-counterfeiting codes with a light source comprises a base paper layer 1, a hidden two-dimensional code printing layer 2, a wet composite adhesive layer 3 and an aluminum-plated layer 4 which are laminated in sequence, and the aluminum-plated layer 4 contains laser information. This method can achieve the purpose of hiding without adding too much raw materials, affecting the packaging aesthetics, or changing the existing packaging design, thereby improving the packaging process barrier and anti-counterfeiting strength.

[0030] The structure of each layer is as follows:

[0031] Base paper layer 1 can be selected from 80g / m 2 Up to 350g / m 2, the hidden two-dimensional code printing layer 2 is printed on one side of the base paper layer 1 by a printing machine. When printing the two-dimensional code, the layout design can be carried out according to the actual situation. If the printing position of the two-dimensional code needs to be fixed, horizontal and vertical positioning tracking lines should be printed together to ensure that the two-dimensional code can be printed at the specified position. If it is to be printed at a random position of the base paper layer 1, it is necessary to ensure that the two-dimensional code is not at the waste discharge position when it is actually boxed to ensure the integrity of the two-dimensional code.

[0032] The wet composite adhesive layer 3 is formed by applying a water-based environmentally friendly adhesive to the aluminum-plated layer 4 through a wet composite method, and then the base paper layer 1 printed with the hidden QR code printing layer 2 and the aluminum-plated layer 4 are wet composited with the wet composite adhesive layer 3. The wet composite process is simple to operate and uses less adhesive, which helps to save corporate costs; at the same time, the wet composite process has a fast composite rate, which helps to improve the production efficiency of anti-counterfeiting packaging paper. Among them, the solid content of the water-based environmentally friendly adhesive is 40% to 50%, the pH value is 5.5 to 8.5, the viscosity measured under the conditions of coating a No. 4 cup and a temperature of 25°C is 19 to 32 seconds, and the coating amount is 5 to 6g / m 2 The compounding temperature is 85-115°C and the compounding speed is 60-100m / min.

[0033] The present embodiment also includes a film substrate, a transparent acrylic water-based paint information layer is coated on the film substrate, and a laser image is formed by molding, and then an aluminum-plated layer 4 is formed by high vacuum aluminum plating, and the aluminum-plated thickness of the aluminum-plated layer 4 is between 300 and 360Å. The surface of the aluminum-plated layer 4 is very flat and tight, without defects such as cracks and holes. In addition, if the original packaging is a transfer aluminum-plated paper, the above-mentioned aluminum-plated layer 4 is a transfer aluminum-plated layer 4, and the transfer aluminum-plated layer includes an aluminum sublayer and a transfer coating sublayer. If the original packaging is PET aluminum-plated paper, the above-mentioned aluminum-plated layer 4 is a PET aluminum-plated layer, and the PET aluminum-plated layer includes a PET sublayer, an aluminum sublayer, and a water-based environmentally friendly varnish sublayer.

[0034] In addition, considering the convenience of scanning for consumers, the first two-dimensional code printing layer 5 is printed on the side of the base paper layer 1 away from the aluminum-plated layer 4, and / or the second two-dimensional code printing layer 6 is printed on the side of the aluminum-plated layer 4 away from the base paper layer 1, that is, the two-dimensional code can be repeatedly printed on the surface of the packaging paper or / and the inside of the packaging paper according to needs. In actual use, it is only necessary to check whether the two-dimensional code on the surface of the packaging paper or / and the inside of the packaging paper is the same as the two-dimensional code on the hidden two-dimensional code printing layer 2 to complete the authenticity identification.

[0035] The implementation principle of the laser holographic packaging material with a light source that reproduces an anti-counterfeiting code in the embodiment of the present application is as follows: by arranging a two-dimensional code printing layer on the side of the base paper layer 1 close to the aluminum-plated layer 4, when the anti-counterfeiting packaging paper is illuminated by a light source from the back, the anti-counterfeiting two-dimensional code printed on the base paper layer 1 can be clearly observed through the aluminum-plated layer 4, thereby achieving the effect of hiding the two-dimensional code without adding too much raw materials, affecting the aesthetics of the packaging, or changing the existing packaging design, thereby improving the technological barriers and anti-counterfeiting strength of the packaging.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
