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

[0002] Anti-counterfeiting self-adhesive labels are a type of anti-counterfeiting label. They are in the form of self-adhesive labels and are made through a series of complex processes to have anti-counterfeiting functions. The manufacturing process of anti-counterfeiting self-adhesive labels involves using printable quality paper as the base material, and then coating it with adhesive so that it can adhere firmly to a special release backing paper. After that, through a series of delicate process steps, including surface printing to present the required information, integrating advanced anti-counterfeiting technology, printing unique anti-counterfeiting codes, adding scratchable coatings to protect anti-counterfeiting information, covering with protective films to enhance durability and aesthetics, accurately cutting edges and shapes, and die-cutting, a self-adhesive label with anti-counterfeiting functions is finally made. These labels not only have the convenience of self-adhesive labels, but also incorporate a variety of anti-counterfeiting technologies to ensure the authenticity and safety of the products.

[0003] The patent with the publication date of October 24, 2023 and the announcement number of CN219891821U discloses an anti-counterfeiting self-adhesive label, which includes a backing paper for protecting the label from being contaminated during use and providing support to ensure that the label is not easy to bend or curl, a self-adhesive coating, which is located at the upper layer of the backing paper, and is used for attaching the label base layer to the backing paper before the label is attached to the surface of an object, an anti-bulging layer, which is located above the self-adhesive coating, and is used to discharge bubbles between the label and the attached object, a heat-insulating coating, which is located on the upper layer of the anti-bulging layer, a label graphic layer, which is located on the upper layer of the heat-insulating coating, and is used to print graphic information and anti-counterfeiting barcodes, and a protective layer, which is located on the upper layer of the label graphic layer, and is used to improve surface tension and provide protection for the label graphic layer. The anti-counterfeiting self-adhesive label is isolated by setting a heat-insulating coating, and the anti-bulging layer is set to reduce bulging between the label and the attached object, so that the label is flat.

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0023] Anti-counterfeiting self-adhesive labels are a type of anti-counterfeiting label. They are in the form of self-adhesive labels and are made through a series of complex processes to have anti-counterfeiting functions. The manufacturing process of anti-counterfeiting self-adhesive labels involves using printable quality paper as the base material, and then coating it with adhesive so that it can adhere firmly to a special release backing paper. After that, through a series of delicate process steps, including surface printing to present the required information, integrating advanced anti-counterfeiting technology, printing unique anti-counterfeiting codes, adding scratchable coatings to protect anti-counterfeiting information, covering with protective films to enhance durability and aesthetics, accurately cutting edges and shapes, and die-cutting, a self-adhesive label with anti-counterfeiting functions is finally made. These labels not only have the convenience of self-adhesive labels, but also incorporate a variety of anti-counterfeiting technologies to ensure the authenticity and safety of the products.

[0024] At present, the anti-counterfeiting measures adopted by most anti-counterfeiting self-adhesive labels need to be observed with the naked eye. Even if it is a QR code, it is still based on visual anti-counterfeiting. These visual anti-counterfeiting measures are easy to be copied. The above scheme takes into account the reduction of bulging between the label and the object to be attached, making the label smooth, but the anti-counterfeiting means are relatively simple, and it is easy for criminals to steal the anti-counterfeiting mark and use it, thereby causing economic losses.

[0025] Based on this, in order to improve the problem that most anti-counterfeiting self-adhesive label anti-counterfeiting methods in the related art tend to be visual anti-counterfeiting, which is easy for criminals to steal the anti-counterfeiting marks and use them, thereby causing economic losses, the embodiments of the present application provide the following solutions.

[0026] Please also read Figure 1 The embodiment of the present application provides an anti-counterfeiting self-adhesive label, comprising an anti-counterfeiting layer 1, an adhesive layer 2, and an information layer 3. The anti-counterfeiting layer 1 is bonded to the upper side of the adhesive layer 2, the information layer 3 is bonded to the upper side of the anti-counterfeiting layer 1, and a backing paper 4 is bonded to the lower side of the adhesive layer 2. The anti-counterfeiting layer 1 is provided with a groove, an ID chip 5 is arranged in the groove, and one side of the ID chip 5 is in contact with the groove.

[0027] With this arrangement, the backing paper 4 provides support to ensure that the label is not easy to bend or curl before use. The addition of the ID chip 5 makes the anti-counterfeiting self-adhesive label have a function similar to that of an IC card. When the label is close to the reader / writer paired with the ID chip 5 inside the label, the reader / writer can read and enter information from the ID chip 5. The manufacturer of the self-adhesive label packages the anti-counterfeiting self-adhesive label and the corresponding card reader for sale. The manufacturer of the product to be pasted with the anti-counterfeiting self-adhesive label can use the reader / writer to enter the production date, instructions for use and other product-related information on the ID chip 5. Product manufacturers supply products to specialty stores. Each time a product is sold, the specialty store can use a card reader to enter the purchaser's name, telephone number, purchase time and other information into the ID chip 5 in the anti-counterfeiting self-adhesive label. After the consumer confirms the authenticity of the product or has finished using the product, the consumer can bring the original product packaging with the intact anti-counterfeiting self-adhesive label to the specialty store and use it as a discount coupon when purchasing the product next time. This stimulates consumers' circular consumption while recycling the ID chip 5. The manufacturer deletes the record and re-enters the information to achieve the recycling of the ID chip 5.

[0028] Optionally, in some embodiments, please refer to Figure 2 as well as Figure 3 A coil 6 is also provided on the anti-counterfeiting layer 1. The coil 6 is C-shaped and also abuts against the groove of the anti-counterfeiting layer 1. The chip is placed in the C-shaped notch of the coil 6. The coil 6 is electrically connected to the ID chip 5 through a conductive wire 7.

[0029] With such a configuration, when the card reader is close to the anti-counterfeiting self-adhesive label, the card reader will emit electromagnetic waves of a fixed frequency, and the coil 6, as an induction antenna, receives these electromagnetic wave signals, thereby generating an induced electromotive force in the coil 6, and then generating an induced current. The current enters the ID chip 5 through the conductive wire 7, that is, the electromagnetic wave energy received by the coil 6 is converted and accumulated through the LC series resonant circuit. The frequency characteristics of the LC resonant circuit are the same as the frequency emitted by the reader, generating a resonance effect, so that the charge is continuously accumulated. When the charge accumulates to a certain extent, the charge is transmitted through a unidirectional conductive electron pump as the power supply of the chip. After having enough electrical energy, the ID chip 5 starts to work, and the chip sends the information or data stored in the card back to the card reader through the coil 6 in the form of electromagnetic waves. The card reader receives and analyzes these signals, thereby completing the data reading or writing operation.

[0030] Optionally, in some embodiments, please refer to Figure 1The adhesive layer 2 includes a self-adhesive layer 21 and a heat-insulating coating 22. The heat-insulating coating 22 is bonded to the lower side of the anti-counterfeiting layer 1. The self-adhesive layer 21 is bonded to the lower side of the heat-insulating coating 22. The backing paper 4 is bonded to the lower side of the self-adhesive layer 21. The surface of the backing paper 4 where the self-adhesive layer 21 is bonded is coated with an oil film.

[0031] In this way, the surface of the self-adhesive layer 21 in contact with the backing paper 4 is coated with an oil film, so that the anti-counterfeiting self-adhesive label can be easily torn off from the backing paper 4 without affecting the adhesive stickiness of the self-adhesive layer 21. At present, many self-adhesive labels will have a decrease in stickiness and automatically fall off under high temperature conditions. The heat insulation coating 22 is designed between the self-adhesive layer 21 and other adhesive layers, which can ensure the temperature of the self-adhesive layer 21 to a certain extent, so that the anti-counterfeiting self-adhesive label will not be easily removed from the product packaging without damage.

[0032] Optionally, in some embodiments, please refer to Figure 1 The information layer 3 includes a paper printing layer 31 and a waterproof and oil-proof film 32. The paper printing layer 31 is bonded to the upper side of the anti-counterfeiting layer 1. The waterproof and oil-proof coating is bonded to the upper side of the paper printing layer 31, and the waterproof and oil-proof coating is a transparent film.

[0033] With such a configuration, simple text, graphics and other visual information can be printed on the paper printing layer 31 to explain the relevant information of the product, and some visual anti-counterfeiting measures can be added, including but not limited to, introducing new optically variable inks in the paper printing layer 31, using more advanced optically variable inks, these inks can present more diverse color changes under different angles or light sources, such as purple to green, blue to red and other color-changing effects, increasing the difficulty of counterfeiting; invisible inks combined with special light sources, invisible inks that can display color under different bands such as ultraviolet rays and infrared rays, improve the concealment and readability of anti-counterfeiting information, and provide consumers with portable detection tools (such as ultraviolet lamps, infrared pens, etc.), so that they can conduct anti-counterfeiting verification anytime and anywhere; anti-counterfeiting information is hidden in the label through special printing processes such as microtext, and this information can only be seen or read using specific tools or methods such as magnifying glasses, and unique anti-counterfeiting labels are customized for different products or batches, including anti-counterfeiting codes, patterns, colors, etc., so that each anti-counterfeiting label is unique. In this way, even if someone tries to forge it, it is difficult to make it completely consistent with the original. After the relevant information on the paper printing layer 31 is prepared, a coating is applied on its surface to form a waterproof and oil-proof coating. This coating is transparent, which can ensure that the anti-counterfeiting logo, product information, etc. on the paper printing layer 31 can be seen, and can also protect these anti-counterfeiting logos, product information, etc. from being easily destroyed.

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
