Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting materials technology, specifically to an anti-counterfeiting label and product. Background Technology

[0002] Anti-counterfeiting labels are marks affixed to the surface of products or packaging, serving an anti-counterfeiting function. Their main purpose is to help consumers identify genuine products, ensuring that the purchased goods are authentic and thus protecting consumer rights.

[0003] Currently, anti-counterfeiting labels are mainly bonded to products using pressure-sensitive adhesive. For example, patent document CN118298710A discloses a tamper-evident holographic anti-counterfeiting label. The bottom of the holographic laser information layer is provided with a pressure-sensitive adhesive layer, and the bottom of the pressure-sensitive adhesive layer is provided with a release paper layer. After removing the release paper, the label can be pasted onto the product.

[0004] Although these traditional label structures have a QR code verification layer, this verification method essentially verifies the authenticity of the label itself. As long as the label is completely peeled off the product, it can be reused on other products, making it difficult for consumers to identify.

[0005] In addition, heating can soften the pressure-sensitive adhesive, and soaking it in a specific solvent can also cause it to lose its stickiness or dissolve. Both of these methods can make the label completely removed from the object, greatly reducing the effectiveness of the anti-counterfeiting label. Utility Model Content

[0006] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide an anti-counterfeiting label and product.

[0007] The anti-counterfeiting label provided by this utility model includes: a face label layer and an adhesive layer.

[0008] The label layer comprises a substrate layer, a first fragile layer, an anti-counterfeiting layer, a second fragile layer, and a coating layer.

[0009] The substrate layer is a heat-shrinkable layer, which is one or more of heat-shrinkable PET film and heat-shrinkable PVC film.

[0010] The anti-counterfeiting layer includes a first optical structure layer, one side of which is connected to the first fragile layer, and the other side is connected to the second fragile layer and the coating layer, respectively. Alternatively, the anti-counterfeiting layer includes an information layer and a first optical structure layer. One side of the first optical structure layer is connected to both the first fragile layer and the information layer, and the opposite side is connected to both the second fragile layer and the coating layer. Alternatively, the anti-counterfeiting layer includes a first optical structure layer and an information layer. One side of the first optical structure layer is connected to the first fragile layer, and the opposite side is connected to the information layer, the second fragile layer, and the coating layer.

[0011] The first optical structure layer includes one or more optical structure regions and one or more non-optical structure regions.

[0012] The non-optical structural region is a coating of uniform thickness.

[0013] The optical effects include presenting micro-nano graphics and / or laser holographic effects.

[0014] The faceplate layer also includes a second optical structure layer, which is adjacent to the side of the substrate layer away from the first fragile layer.

[0015] The second fragile layer is a resin-based material layer that can be dissolved in a solvent. The resin-based material layer is one or more of the following: oil-based ink, water-based ink, low molecular weight UV ink, polyacrylic resin, polyurethane resin, and polyester.

[0016] The coating layer provides a reflective effect or increases the refractive index. The coating layer is made of metal or non-metal, and the coating layer material is aluminum or zinc sulfide.

[0017] The adhesive layer is a pressure-sensitive adhesive.

[0018] The first fragile layer is located on one side of the substrate layer and is connected to the substrate layer. The side of the first fragile layer away from the substrate layer is connected to the anti-counterfeiting layer. The second fragile layer is connected to the side of the anti-counterfeiting layer away from the first fragile layer. The coating layer is connected to the side of the second fragile layer and the anti-counterfeiting layer away from the first fragile layer.

[0019] The first fragile layer is a full-page layer.

[0020] The non-optical structural regions of the first optical structural layer are wholly or partially connected to the second fragile layer.

[0021] The optical structure region of the first optical structure layer is partially connected to or completely disconnected from the second fragile layer.

[0022] The peel force between the second fragile layer and the anti-counterfeiting layer is less than the peel force between the first fragile layer and the substrate layer.

[0023] The coating layer is connected to the optical structure regions of the second fragile layer and the first optical structure layer, respectively.

[0024] Alternatively, the coating layer is connected to the optical structure region and a portion of the non-optical structure region of the second fragile layer and the first optical structure layer, respectively. Alternatively, the coating layer is connected to the second fragile layer, a portion of the non-optical structure region, and the information layer, respectively.

[0025] The side of the coating layer away from the anti-counterfeiting layer is connected to the adhesive layer.

[0026] According to the present invention, a product includes the aforementioned anti-counterfeiting label and a product body, wherein the anti-counterfeiting label is attached to the product body by an adhesive layer.

[0027] Compared with the prior art, the present invention has the following beneficial effects: When the anti-counterfeiting label of this invention is peeled off, the integrity of the label's coating layer and anti-counterfeiting layer will be damaged, making the label difficult to repair and reuse.

Attached Figure Description

[0028] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings: Figure 1 This is a schematic diagram of the structure of one embodiment of the present utility model; Figure 2 This is a schematic diagram of the first optical structure layer; Figure 3 This is a diagram showing the state after the anti-counterfeiting label has been properly peeled off. Figure 4 This is a schematic diagram of another embodiment of the present invention. Detailed Implementation

[0029] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0030] Example 1 like Figure 1 As shown, this embodiment provides an anti-counterfeiting label, including: a face label layer and an adhesive layer 1, wherein the face label layer includes: a substrate layer 2, a first fragile layer 3, an anti-counterfeiting layer 4, a second fragile layer 5, and a coating layer 6.

[0031] The first fragile layer 3 is located on one side of the substrate layer 2 and is connected to the substrate layer 2. The side of the first fragile layer 3 away from the substrate layer 2 is connected to the anti-counterfeiting layer 4. The second fragile layer 5 is connected to the side of the anti-counterfeiting layer 4 away from the first fragile layer 3. The coating layer 6 is connected to the side of the second fragile layer 5 and the anti-counterfeiting layer 4 away from the first fragile layer 3. The side of the coating layer 6 away from the anti-counterfeiting layer 4 is connected to the adhesive layer 1. The peel force between the second fragile layer 5 and the anti-counterfeiting layer 4 is less than the peel force between the first fragile layer 3 and the substrate layer 2. The label layer may also include a second optical structure layer 7, which is connected to the side of the substrate layer 2 away from the first fragile layer 3. The second optical structure layer 7 may be a microlens structure, thereby enhancing the visual effect of the anti-counterfeiting layer 4 below the second optical structure layer 7.

[0032] like Figure 1 As shown, in one embodiment, the anti-counterfeiting layer 4 includes a first optical structure layer 41, one side of which is connected to the first fragile layer 3, and the opposite side is connected to the second fragile layer 5 and the coating layer 6, respectively. In another embodiment, the anti-counterfeiting layer 4 includes a first optical structure layer 41 and an information layer 42, one side of which is connected to the first fragile layer 3 and the information layer 42, and the opposite side is connected to the second fragile layer 5 and the coating layer 6, respectively. The information layer 42 is visible to the naked eye and may contain patterns, text, numbers, and / or QR code information. The pattern may be a graphic or a combination of one color or multiple colors.

[0033] like Figure 2 As shown, the first optical structure layer 41 includes one or more optical structure regions 411 and one or more non-optical structure regions 412. Optical structure regions 411 refer to regions capable of producing optical effects, formed by uneven structures creating different refractive indices to produce optical effects. Non-optical structure regions 412 refer to regions that cannot produce optical effects, generally formed by a uniformly thick coating. Optical effects include presenting micro / nano graphics and / or laser holographic effects. Micro / nano graphics refer to patterns or text formed by micrometer or nanometer-level optical structures. Laser holographic effects include embossing, optical variable effects, isomorphic effects, cat's eye effects, microtext, dynamic gratings, rainbow holography, and light spot reproduction. Figure 4 As shown, in other embodiments, the first optical structure layer 41 may also be connected to the fragile layer 3 on one side and to the information layer 42, the second fragile layer 5, and the coating layer 6 on the other side. The projection of the second optical structure layer 7 in the vertical direction may partially or completely overlap with the optical structure region 411 in the first optical structure layer 41, thereby enhancing the visual effect of the optical structure region 411.

[0034] In this embodiment, the non-optical structure region 412 is wholly or partially connected to the second fragile layer 5, while the optical structure region 411 is partially or not connected to the second fragile layer 5. This avoids the situation where the coating layer 6 below the optical structure region 411 is not visible to the naked eye due to the obstruction of the optical structure region 411.

[0035] The coating layer 6 is connected to the second fragile layer 5 and the optical structure region 411; or, the coating layer 6 is connected to the second fragile layer 5, the optical structure region 411, and part of the non-optical structure region 412; or, the coating layer 6 is connected to the second fragile layer 5, part of the non-optical structure region 412, and the information layer 42 respectively. The coating layer 6 mainly provides a reflective effect or increases the refractive index for the optical structure. The material can be metal or non-metal, such as aluminum or zinc sulfide.

[0036] The adhesive layer 1 serves to bond with the external product, typically using pressure-sensitive adhesive, preferably a pressure-sensitive adhesive based on polyacrylate, polyurethane, or rubber systems. Considering that pressure-sensitive adhesives soften easily when heated, and the label can be easily removed from the external product for reuse, the substrate layer 2 in this embodiment is a heat-shrinkable layer, including one or more heat-shrinkable film materials, such as heat-shrinkable PET film or heat-shrinkable PVC film. Upon heating, the material shrinks, damaging the label and making it difficult to reuse. The first fragile layer 3 is a full-coverage layer, meaning it completely covers the side where it meets the substrate layer 2 and the anti-counterfeiting layer 4, leaving no blank areas. This allows the entire label to shrink synchronously when heated at any point on the substrate layer 2, making the shape change of the label clearly observable. Considering that pressure-sensitive adhesives can be dissolved by specific solvents, and the label can be easily removed from the external product for reuse, the second fragile layer 5 is a resin material layer that can be dissolved in solvents, such as oil-based inks, water-based inks, low molecular weight UV inks, polyacrylic resin, polyurethane resin, or polyester, or one or more of these. If the anti-counterfeiting label is soaked in a solvent to dissolve the adhesive layer 1, the second fragile layer 5 will also be dissolved.

[0037] Working principle: When the anti-counterfeiting label is peeled off normally, the adhesive force between the adhesive layer 1 and the object being labeled is greater than the peel force between the second fragile layer 5 and the anti-counterfeiting layer 4. The second fragile layer 5 separates from the first optical structure layer 41. The coating layer 6, because part of it is attached to the second fragile layer 5 and part to the first optical structure layer 41, also breaks and separates, compromising its integrity. The first fragile layer 3, which is not within the vertical projection area of ​​the second fragile layer 5, separates from the substrate layer 2. Part of the anti-counterfeiting layer 4 separates with the peeled-off portion, while part remains on the coating layer 6. Figure 3 As shown, the integrity is thus compromised.

[0038] When the anti-counterfeiting label is heated, the adhesive layer 1 softens and loses its stickiness, and the heat-shrinkable material of the substrate layer 2 undergoes irreversible shrinkage, causing the anti-counterfeiting label to deform as a whole and become unusable.

[0039] When the label comes into contact with the solvent, the adhesive layer 1 loses its stickiness, and the second fragile layer 5 also comes into contact with the solvent and dissolves, causing the coating layer 6 to lose its support and thus separate from the label as a whole, causing irreversible damage to the label.

[0040] Example 2 This embodiment provides a product, including the anti-counterfeiting label of Embodiment 1 and the product body. The anti-counterfeiting label is adhered to the product body by an adhesive layer. The product body can be a packaging box, container, etc. The anti-counterfeiting label can be pasted on the seal of the product body, thereby indicating whether the product has been opened or replaced, and playing a role in anti-counterfeiting.
