Description

Technical Field

[0001] The utility model relates to the technical field of labels, in particular to an anti-copying and anti-counterfeiting label. Background Art

[0002] As an important means to protect the brand image of goods, anti-counterfeiting labels have various anti-counterfeiting methods, such as anti-counterfeiting substrates, anti-counterfeiting inks, QR codes, anti-counterfeiting textures, anti-counterfeiting pigments, etc. Among them, anti-counterfeiting substrates account for a relatively high proportion of applications in anti-counterfeiting labels, and their high anti-counterfeiting performance and high appearance are popular in the market. When the anti-counterfeiting substrate is paper, an anti-counterfeiting film is required. The anti-counterfeiting film often uses customized anti-counterfeiting optical textures or patterns. The anti-counterfeiting texture or pattern is formed on the anti-counterfeiting film layer, so that the product can be clearly distinguished from other products in appearance. Since the anti-counterfeiting texture or pattern on the anti-counterfeiting film needs to be protected and brightened by the vapor-deposited aluminum layer to be perfectly presented, and the aluminum layer itself is not alkali-resistant, counterfeiters can use alkali solution (usually 8-12wt% NaOH solution) to wash off the aluminum layer in a short time (within 2 minutes) (i.e., wash aluminum), so that the anti-counterfeiting pattern on the anti-counterfeiting film layer is separated from the aluminum layer intactly, and the integrity of the anti-counterfeiting pattern after cleaning can reach more than 90%. Counterfeiters can directly copy it through professional plate-making equipment or directly read the anti-counterfeiting pattern texture through identification and reading equipment to achieve the purpose of counterfeiting.

[0003] Therefore, how to avoid counterfeiting through alkaline solution cleaning and peeling so that counterfeiters cannot copy and imitate is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides an anti-copying anti-counterfeiting label, which will destroy the anti-counterfeiting information when it is washed and peeled off with alkali solution, and cannot be copied and imitated.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] An anti-copying and anti-counterfeiting label comprises, from top to bottom, a film, a printing layer, an anti-copying UV coating, a micro-nano graphic anti-counterfeiting layer and an anti-counterfeiting aluminum-plated layer.

[0007] The utility model has at least the following beneficial effects: the anti-copying UV coating is the key to perfectly presenting the micro-nano graphic anti-counterfeiting layer, and its alkali resistance is poor. When a counterfeiter uses alkali solution to clean the aluminum layer to peel off the graphic information, it will also directly cause corrosion damage to the surface of the anti-copying UV coating, causing serious loss of graphic information within 30 seconds and making it unusable, thereby achieving the anti-copying effect; through the triple anti-counterfeiting of anti-copying UV coating + micro-nano graphic anti-counterfeiting layer + anti-counterfeiting aluminum plating layer, the anti-counterfeiting level of the label can be improved, and the visual effect of the appearance is more three-dimensional. At the same time, it can effectively solve the problem of counterfeiters copying the micro-nano graphic after cleaning the aluminum layer with alkali solution, thereby achieving high anti-counterfeiting protection for the product brand.

[0008] As a further improvement of the above technical solution, an adhesion promoting layer is provided between the printing layer and the anti-copying UV coating. The adhesion promoting layer can improve the bonding strength between the printing layer and the anti-copying UV coating.

[0009] As a further improvement of the above technical solution, the bottom surface of the anti-counterfeiting aluminum-plated layer is provided with a back adhesive protective layer. The back adhesive layer can provide protection for the anti-counterfeiting aluminum-plated layer, prevent the aluminum layer from oxidizing and blackening and being scratched, and at the same time provide good connection performance for subsequent label glue lamination.

[0010] As a further improvement of the above technical solution, the film is a PET film, and the thickness of the film is 30 to 50 μm.

[0011] As a further improvement of the above technical solution, the printing layer is provided with label graphic information.

[0012] As a further improvement of the above technical solution, the anti-copying UV coating is formed by curing UV varnish under a UV light source, and the thickness of the anti-copying UV coating is 4 to 12 μm.

[0013] As a further improvement of the above technical solution, the micro-nano graphic anti-counterfeiting layer is provided with a micro-nano structure. The micro-nano structure has a 3D stereoscopic visual effect, which has a visual anti-counterfeiting effect compared with ordinary laser labels and can improve the grade and anti-counterfeiting performance of the product.

[0014] As a further improvement of the above technical solution, the anti-counterfeiting aluminum plating layer is provided with a micro-text pattern, and the thickness of the anti-counterfeiting aluminum plating layer is 150 to Setting a microtext pattern, hiding the anti-counterfeiting microtext in the aluminized layer, the microtext pattern can be observed with the naked eye under strong light and a magnifying glass, which can increase the anti-counterfeiting performance of the label. The thickness of the aluminized layer has a direct impact on the visibility of the microtext. If it is too thin or too thick, it will be difficult to observe the microtext pattern.

[0015] As a further improvement of the above technical solution, the adhesion promoting layer adopts water-based resin, and the thickness of the adhesion promoting layer is 0.2-0.5 μm.

[0016] As a further improvement of the above technical solution, the adhesive back protective layer is made of water-based acrylic resin, and the thickness of the adhesive back protective layer is 0.5 to 2 μm. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connecting accessories according to the specific implementation situation. The various technical features in the utility model can be combined interchangeably without conflicting with each other.

[0021] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] Reference Figure 1 The embodiment of the utility model proposes an anti-copying and anti-counterfeiting label, which includes, from top to bottom, a film 1, a printing layer 2, an adhesion promoting layer 3, an anti-copying UV coating 4, a micro-nano graphic anti-counterfeiting layer 5, an anti-counterfeiting aluminum plating layer 6 and a back adhesive protective layer 7.

[0025] Specifically, the film 1, as the main carrier of the label, requires low thermal shrinkage and deformation capability to ensure the positioning accuracy during the production process of the anti-counterfeiting micro-nano film 1. The film 1 is made of PET film 1 with a thickness of 30 to 50 μm.

[0026] The printing layer 2 is provided with label graphic information, which can display the label graphic information. It can be understood that the printing layer 2 is an ink layer printed with one or more inks, mainly conventional acrylic resin, and can be printed on the film 1 by back printing and surface printing. Back printing is preferred, which is not easy to wear and fall off, and is more durable and stable.

[0027] The adhesion promoting layer 3 is made of conventional water-based resin. It is understood that the water-based resin includes water-based acrylic acid, water-based polyurethane, epoxy resin, etc. The adhesion promoting layer 3 formed by coating the water-based resin on the printing layer 2 can make the printing layer 2 and the anti-copying UV coating 4 more firmly and stably bonded. The thickness of the adhesion promoting layer 3 is set to 0.2-0.5 μm.

[0028] The anti-copying UV coating 4 uses the existing UV varnish (laser composite UV varnish, purchased from Hebei Zhisheng Environmental Protection Technology Co., Ltd.), which is coated on the adhesion promotion layer 3 and then cured by a UV light source. The anti-copying UV coating 4 is the key to perfectly presenting the micro-nano graphic anti-counterfeiting layer 5. The cross-linking density of this UV varnish is relatively low and the alkali resistance is poor. When the counterfeiter uses alkali solution (usually 8-12wt% NaOH solution) to clean the aluminum layer to peel off the graphic information, the surface of the UV coating will be directly corroded and damaged, causing serious loss of graphic information within 30s and making it unusable, so as to achieve the anti-copying effect. The thickness of the anti-copying UV coating 4 is set to 4-12μm.

[0029] The micro-nano graphic anti-counterfeiting layer 5 is provided with a micro-nano structure. It is understandable that the micro-nano graphic anti-counterfeiting layer 5 is made by the existing high-precision laser photolithography platemaking technology and positioning molding technology, and the graphics presented have a 3D stereoscopic visual effect, which has a visual anti-counterfeiting effect compared with ordinary laser labels, and can improve the grade and anti-counterfeiting performance of the product.

[0030] The anti-counterfeiting aluminum layer 6 is provided with a micro-text pattern. It is understandable that the anti-counterfeiting aluminum layer 6 hides the anti-counterfeiting micro-text in the aluminum layer by combining the existing micro-text printing and vacuum evaporation process. The micro-text pattern can be observed with the naked eye under strong light and a magnifying glass, which can increase the anti-counterfeiting performance of the label. Since the thickness of the aluminum layer has a direct impact on the appearance of the micro-text, if it is too thin, it is difficult to observe the micro-text pattern, and if it is too thick, the micro-text pattern will be directly visible and affect the appearance of the printing. Therefore, the thickness of the anti-counterfeiting aluminum layer 6 is set to 150~

[0031] The adhesive protective layer 7 is made of conventional water-based acrylic resin, which can provide protection for the anti-counterfeiting aluminum layer 6 to prevent the aluminum layer from being oxidized and blackened and scratched, and can also provide better connection performance for subsequent label glue lamination. The thickness of the adhesive protective layer 7 is set to 0.5-2 μm.

[0032] The anti-copying and anti-counterfeiting label provided in this embodiment adopts a triple anti-counterfeiting superposition technology (anti-copying UV coating + micro-nano graphic anti-counterfeiting layer + anti-counterfeiting aluminum plating layer) in anti-counterfeiting technology, and has extremely high anti-counterfeiting performance. If the counterfeiter uses the industry-standard alkali solution to clean and peel off the anti-counterfeiting graphics, the surface of the anti-copying UV coating will also be corroded, and the anti-counterfeiting micro-nano texture in the micro-nano graphic anti-counterfeiting layer will be destroyed in a short time, and the integrity of the pattern will be less than 50%, making the graphics lose the meaning of copying, achieving the purpose of anti-copying. At the same time, the micro-nano texture of the product has a 3D stereoscopic effect and high brightness, which makes the product more visually attractive in appearance and looks more advanced, which helps to improve the competitiveness of the product.

[0033] The preferred implementation methods of the present invention are specifically described above, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
