Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-adhesive label technology, and in particular to a self-adhesive label with anti-counterfeiting function. Background Technology
[0002] Early self-adhesive labels were mainly used to improve the efficiency of product labeling, replacing the inefficient method of handwritten labels. With the advancement of the Industrial Revolution and the need for mass production, self-adhesive labels rapidly became widespread due to their convenience. However, with economic development and intensified market competition, the problem of counterfeit and substandard products, such as high-value electronic products, concert and sports event tickets, exhibition tickets, and high-end club membership cards, has become increasingly serious, damaging brand reputation and consumer interests. This has prompted enterprises and regulatory agencies to seek more effective anti-counterfeiting measures, and consumers' increased attention to the authenticity of products has also driven the growth in demand for anti-counterfeiting labels.
[0003] In existing technologies, although QR codes, barcodes, or anti-counterfeiting inks can provide a certain degree of anti-counterfeiting function, they are easy to copy or forge, making it difficult to effectively prevent counterfeit and shoddy products. Furthermore, the coating printed with QR codes is directly exposed on the surface and is easily affected by friction, scratches, and chemical corrosion, resulting in unclear label information or even complete indistinguishability. Therefore, a self-adhesive label with anti-counterfeiting function is proposed to solve the above-mentioned problems. Utility Model Content
[0004] In order to address the technical problems in existing technologies such as QR codes, barcodes, or anti-counterfeiting inks, which, although providing a certain degree of anti-counterfeiting function, are easily copied or counterfeited, and whose coatings with QR codes are directly exposed to the surface and are easily affected by friction, scratches, chemical corrosion, etc., this application provides an adhesive label with anti-counterfeiting function.
[0005] This utility model proposes a self-adhesive label with anti-counterfeiting function, which includes a label body, the label body including a backing paper layer, a release layer, a self-adhesive layer, an information layer, a protective layer and a printing layer.
[0006] The label body is equipped with an anti-counterfeiting mechanism, which includes an RFID chip. The RFID chip achieves anti-counterfeiting function through a built-in unique identification code.
[0007] Preferably, the printed layer is located inside the protective layer, the printed layer is made of coated paper, and the protective layer is made of PET film.
[0008] The above technical solution utilizes a printed layer located inside the protective layer, carrying visible printed information such as brand logos, product information, serial numbers, and decorative patterns for brand display and initial information delivery. Made of coated paper, the printed information is directly printed onto the surface using offset, flexographic, or screen printing processes. Coated paper has a smooth surface, high whiteness, excellent ink absorption and color reproduction, resulting in clear and vibrant printing effects. The protective layer covers the outer surface of the printed layer, coated with an acrylic or polyurethane adhesive. The adhesive-coated printed layer and protective layer are then tightly bonded together in a laminator using heat and pressure. The protective layer is made of PET film, which effectively isolates the printed information from external physical and chemical damage.
[0009] Preferably, the information layer is adhered to the lower surface of the protective layer by adhesive, and the information layer is made of cellophane.
[0010] Through the above technical solution, the information layer is bonded to the lower surface of the protective layer with acrylic adhesive or hot melt adhesive, which has good bonding strength and durability, and can firmly bond the information layer and the protective layer together. Some fine structures that are difficult to be seen with the naked eye, such as microtext, special textures, diffraction patterns, etc., can be designed on or inside the cellophane. These can only be seen with the help of a magnifying glass or specific angles / lighting, and are used for basic physical anti-counterfeiting verification. Since the information layer is made of cellophane, it has a certain barrier ability against water vapor and grease, which helps to protect the embedded RFID chip from the effects of environmental factors such as moisture.
[0011] Preferably, the self-adhesive layer is bonded to the lower surface of the information layer, and the self-adhesive layer is made of acrylic pressure-sensitive adhesive.
[0012] The above technical solution provides adhesion between the label body and the final pasting surface by bonding the self-adhesive layer to the lower surface of the information layer, enabling the label body to adhere firmly. The material is acrylic pressure-sensitive adhesive, which has broad adhesion properties and can adhere well to various substrates, including plastics, metals, glass, and paper. This is crucial for applications where the label body needs to be used on different products. Furthermore, it exhibits good resistance to environmental factors such as temperature changes, ultraviolet radiation, and humidity, and is not prone to aging, hardening, or failure, ensuring the label body maintains its adhesiveness for a longer period.
[0013] Preferably, the release layer is located at one corner of the contact surface between the self-adhesive layer and the backing paper layer, the release layer is made of silicone release film, and the backing paper layer is made of coated paper.
[0014] The above technical solution involves a release layer that adheres tightly to a corner of the backing paper layer, without covering the entire adhesive layer, but still in contact with it. Its surface is coated with silicone oil, giving it low surface energy, allowing it to be easily peeled off the adhesive layer without removing the adhesive. The release layer's design allows users to easily tear off the backing paper layer through the exposed corner. Made of silicone oil release film, the backing paper layer is attached to the underside of the adhesive layer. In most areas where the backing paper layer and the adhesive layer are in contact, the surface of the backing paper layer is typically coated with a layer of silicone oil. This silicone oil allows the adhesive layer to temporarily and stably adhere to the backing paper layer during label production, storage, and transportation, preventing the adhesive layer from prematurely adhering to other objects or sticking to itself. The backing paper layer is made of coated paper.
[0015] Preferably, the anti-counterfeiting mechanism further includes a protective edge, which is affixed to the outer surface of the label body. The protective edge is made of fluorescent hydrogel, and the RFID chip is located inside the information layer.
[0016] The above technical solution involves attaching a protective edge to the outer surface of the label body to protect it from all sides. The edge has a semi-circular cross-section, which can buffer external impacts or pressure to a certain extent, reducing direct damage to the label body. The semi-circular outline is also relatively soft and more aesthetically pleasing than sharp edges or completely flat designs, meeting the appearance requirements of some products or occasions. The edge is made of fluorescent hydrogel, which glows under ultraviolet light of a specific wavelength, serving as an anti-counterfeiting feature. Only manufacturers with specific formulas and production processes can produce this specific fluorescent effect. A pressure-sensitive adhesive is applied to the contact surface with the label body for added fixation. An RFID chip is located inside the information layer, and its model is selected according to requirements. For example, for high-end club membership cards or electronic products, a high-frequency HF (13.56MHz) NFC chip or an ISO 15693 standard chip can be selected. These chips have moderate reading distances, good anti-interference capabilities, and the widespread availability of NFC technology facilitates user interaction and verification via mobile phone. The beneficial effect is that it provides a convenient and secure authentication method, while the uniqueness and embedding method of the chip increase the difficulty of counterfeiting.
[0017] The beneficial effects of this utility model are as follows:
[0018] 1. By setting up a base paper layer, a release layer, a self-adhesive layer, an information layer, a protective layer, and a printing layer, the printing layer is located inside the protective layer and carries visible printed information, such as brand logos, product information, serial numbers, decorative patterns, etc., for brand display and initial information transmission. The protective layer covers the outer surface of the printing layer, protecting the printed information underneath from damage. Some fine structures that are difficult to be detected by the naked eye can be designed on the surface or inside of the information layer for basic physical anti-counterfeiting verification. The self-adhesive layer is bonded to the lower surface of the information layer, providing adhesion between the label body and the final pasting surface. The release layer is attached to a corner of the base paper layer, not covering the entire self-adhesive layer, but in contact with the self-adhesive layer. Its surface is coated with silicone oil, which has low surface energy, allowing it to be easily peeled off from the self-adhesive layer without taking away the adhesive. This solves the technical problem in the prior art where the coating with the QR code printed on it is directly exposed on the surface, making it susceptible to friction, scratches, chemical corrosion, etc., resulting in unclear label information or even complete unrecognizable information.
[0019] 2. By setting up an anti-counterfeiting mechanism, the anti-counterfeiting function is achieved. The protective edge is pasted on the outer side of the label body to protect the label body from all sides. The RFID chip is located inside the information layer, and its model is selected according to the needs. For example, for high-end club membership cards or electronic products, a high-frequency HF, 13.56MHz NFC chip or an ISO 15693 standard chip can be selected. They have a moderate reading distance, good anti-interference ability, and the widespread use of NFC technology makes it easy for users to verify with their mobile phones. Its beneficial effect is that it provides a convenient and secure identity verification method. At the same time, the uniqueness of the chip and the embedding method increase the difficulty of counterfeiting. This solves the technical problem that although existing technologies such as QR codes, barcodes, or anti-counterfeiting inks can provide a certain degree of anti-counterfeiting function, they are easy to be copied or counterfeited and are difficult to effectively prevent counterfeit and shoddy products.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Reference Figures 1-5 A self-adhesive label with anti-counterfeiting function includes a label body 1, which includes a backing paper layer 51, a release layer 5, a self-adhesive layer 4, an information layer 3, a protective layer 21, and a printing layer 2.
[0028] The printing layer 2 is located inside the protective layer 21. The printing layer 2 is made of coated paper, while the protective layer 21 is made of PET film. The printing layer 2, located inside the protective layer 21, carries visible printed information, such as brand logos, product information, serial numbers, and decorative patterns, for brand display and initial information transmission. Because it is made of coated paper, the printed information is directly printed onto the surface of the coated paper through processes such as offset printing, flexographic printing, and screen printing. Coated paper has a smooth surface, high whiteness, good ink absorption and color reproduction, and can present clear and vivid printing effects. The protective layer 21 covers the outer surface of the printing layer 2. An acrylic or polyurethane adhesive is coated on the outer surface of the printing layer 2. The printing layer 2 with adhesive and the protective layer 21 are tightly bonded together on a laminator by heating and pressurizing. Because the protective layer 21 is made of PET film, the PET film can effectively isolate external physical and chemical damage, protecting the printed information underneath from damage.
[0029] Information layer 3 is bonded to the lower surface of protective layer 21 with adhesive. The material of information layer 3 is cellophane. Information layer 3 is bonded to the lower surface of protective layer 21 with acrylic adhesive or hot melt adhesive, which has good bonding strength and durability, and can firmly bond information layer 3 and protective layer 21 together. Some fine structures that are difficult to be detected by the naked eye, such as microtext, special textures, diffraction patterns, etc., can be designed on or inside the cellophane. These can only be seen with the help of a magnifying glass or specific angles / light, and are used for basic physical anti-counterfeiting verification. Since information layer 3 is made of cellophane, it has a certain barrier ability against water vapor and grease, which helps to protect the embedded RFID chip 61 from the effects of environmental factors such as moisture.
[0030] The self-adhesive layer 4 is bonded to the lower surface of the information layer 3. The self-adhesive layer 4 is made of acrylic pressure-sensitive adhesive. By bonding the self-adhesive layer 4 to the lower surface of the information layer 3, it provides adhesion between the label body 1 and the final adhesive surface, allowing the label body 1 to adhere firmly. Because its material is acrylic pressure-sensitive adhesive, this material has wide adhesion and can adhere well to a variety of substrates, including plastics, metals, glass, paper, etc. This is very important for situations where the label body 1 needs to be used on different products. It also has good resistance to environmental factors such as temperature changes, ultraviolet rays, and humidity, and is not easy to age, harden or fail, ensuring that the label body 1 maintains its adhesion for a long time.
[0031] The release layer 5 is located at one corner of the contact surface between the self-adhesive layer 4 and the backing paper layer 51. The release layer 5 is made of silicone oil release film, and the backing paper layer 51 is made of coated paper. The release layer 5 adheres tightly to one corner of the backing paper layer 51, without covering the entire self-adhesive layer 4, but it is in contact with the self-adhesive layer 4. Its surface is coated with silicone oil, which has low surface energy, allowing it to be easily peeled off from the self-adhesive layer 4 without taking away the adhesive. The design of the release layer 5 makes it easy for users to peel off the exposed corner. The backing paper layer 51, made of silicone release film, is adhered to the lower surface of the self-adhesive layer 4. In most areas where the backing paper layer 51 and the self-adhesive layer 4 are in contact, the surface of the backing paper layer 51 is usually coated with a layer of silicone oil. The function of this layer of silicone oil is to allow the self-adhesive layer 4 to temporarily and stably adhere to the backing paper layer 51 during label production, storage and transportation, preventing the self-adhesive layer 4 from adhering to other objects or sticking to itself too early. The material of the backing paper layer 51 is coated paper.
[0032] By setting up a base paper layer 51, a release layer 5, an adhesive layer 4, an information layer 3, a protective layer 21, and a printing layer 2, the printing layer 2 is located inside the protective layer 21 and carries visible printed information, such as brand logos, product information, serial numbers, decorative patterns, etc., for brand display and initial information transmission. The protective layer 21 covers the outer surface of the printing layer 2, protecting the printed information underneath from damage. Some minute structures that are difficult to detect with the naked eye can be designed on or inside the information layer 3 for basic physical anti-counterfeiting verification. The adhesive layer 4 adheres... Adhering to the lower surface of the information layer 3, it provides adhesive force between the label body 1 and the final adhesive surface. The release layer 5 is closely attached to one corner of the backing paper layer 51, does not cover the entire self-adhesive layer 4, but is in contact with the self-adhesive layer 4. Its surface is coated with silicone oil and has low surface energy, which allows it to be easily peeled off from the self-adhesive layer 4 without taking away the adhesive. This solves the technical problem in the prior art where the coating with the QR code is directly exposed on the surface and is easily affected by friction, scratches, chemical corrosion, etc., resulting in unclear label information or even complete unrecognizable label information.
[0033] The label body 1 has an anti-counterfeiting mechanism inside, which includes an RFID chip 61. The RFID chip 61 achieves anti-counterfeiting function through a built-in unique identification code.
[0034] The anti-counterfeiting mechanism also includes a protective edge 6, which is affixed to the outer side of the label body 1. The protective edge 6 is made of fluorescent hydrogel. The RFID chip 61 is located inside the information layer 3. By affixing the protective edge 6 to the outer side of the label body 1, it protects the label body 1 from all sides. The protective edge 6 has a semi-circular cross-section, which can buffer external impacts or pressure to a certain extent, reducing direct damage to the label body 1. The semi-circular outline is relatively soft and looks more aesthetically pleasing than sharp edges or completely flat designs, meeting the label appearance requirements of some products or occasions. The protective edge 6 is made of fluorescent hydrogel, which can glow under ultraviolet light of a specific wavelength. This is itself an anti-counterfeiting feature. Only manufacturers with specific formulas and production processes can produce specific fluorescent effects. A pressure-sensitive adhesive is coated on the contact surface with the label body 1 to assist in fixation. The RFID chip 61 is located inside the information layer 3. Its model is selected according to requirements. For example, for high-end club membership cards or electronic products, a high-frequency HF, 13.56MHz NFC chip or ISO chip can be selected. Chips conforming to the 15693 standard have a moderate reading distance, good anti-interference capabilities, and the widespread adoption of NFC technology makes it easy for users to verify data via their mobile phones. Their advantages include providing a convenient and secure method of identity verification, while the uniqueness of the chip and its embedding method increase the difficulty of counterfeiting.
[0035] Anti-counterfeiting mechanisms are implemented to achieve anti-counterfeiting functions. The edge protector 6 is pasted on the outer side of the label body 1 to protect the label body 1 from all sides. The RFID chip 61 is located inside the information layer 3. Its model can be selected according to the needs. For example, for high-end club membership cards or electronic products, a high-frequency HF, 13.56MHz NFC chip or an ISO 15693 standard chip can be selected. They have a moderate reading distance, good anti-interference ability, and NFC technology is popular, making it convenient for users to use mobile phones for interactive verification. Its beneficial effect is that it provides a convenient and secure identity verification method. At the same time, the uniqueness of the chip and the embedding method increase the difficulty of counterfeiting. It solves the technical problem that although existing technologies such as QR codes, barcodes or anti-counterfeiting inks can provide a certain degree of anti-counterfeiting function, they are easy to be copied or counterfeited and are difficult to effectively prevent counterfeit and shoddy products.
[0036] Working principle: First, prepare the information layer 3 with anti-counterfeiting mechanisms such as microtext and embed the RFID chip 61 into it. Then, apply adhesive to the outer surface of the printing layer 2. The printing layer 2 with adhesive and the protective layer 21 are bonded to the outer surface of the printing layer 2 by heating and pressurizing. The information layer 3 with adhesive and the lower part of the protective layer 21 are bonded together to form the core structure of "printing layer 2-protective layer 21-information layer 3". The self-adhesive layer 4 is pasted under the information layer 3. Silicone oil is applied in a large area under the self-adhesive layer 4 to form the main separation area. A small piece of separation layer 5 is pasted in one corner of the backing paper layer 51 for easy tearing. The label body 1 with self-adhesive layer 4 is pasted onto the backing paper layer 51. Finally, fluorescent hydrogel edge protector 6 is pasted on the side of the label body 1 to complete the production of the label body 1.
[0037] When using the label body 1, the user holds the pre-reserved separation layer 5 on the backing paper layer 51 and peels the backing paper layer 51 smoothly upwards along the seam between the backing paper layer 51 and the self-adhesive layer 4. The silicone release film will be peeled off along with the backing paper layer 51, exposing the self-adhesive layer 4. Align the exposed self-adhesive layer 4 with the target surface and, starting from one end, gently press the label body 1 to make it contact the target surface. Use your fingers or tools to press evenly from the center outwards to remove air bubbles and ensure that the label body 1 is flat and firmly pasted on the target surface. The edge protector 6 should also be completely pasted in place.
[0038] When physical anti-counterfeiting verification is required, check whether the appearance of the label body 1 has been peeled off or tampered with, especially whether the edge protector 6 is intact and whether there are any signs of being pried open. Use a magnifying glass or a specific angle / light to observe the microtext, special textures, etc. on the information layer 3 and check whether they are consistent with the characteristics of the genuine product. Observe the edge protector 6 under ultraviolet light to confirm whether it emits a specific fluorescence and whether the fluorescent pattern is clear and complete.
[0039] When electronic anti-counterfeiting verification is required, a dedicated RFID reader is brought close to the tag. The reader will read the unique identification code built into the RFID chip 61 and compare the read identification code with the legal serial number registered in the official database. If they match, the tag is genuine; if they do not match or do not exist in the database, it is fake.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
