Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting label technology, specifically a self-adhesive anti-counterfeiting label for tobacco. Background Technology

[0002] The shortcomings of traditional self-adhesive anti-counterfeiting labels in terms of anti-transfer, multi-dimensional anti-counterfeiting verification, and convenient identification are becoming increasingly apparent. There is an urgent need for a new anti-counterfeiting solution that can combine the characteristics of tobacco product packaging with multiple layers of anti-counterfeiting and irreversible use, so as to effectively enhance the anti-counterfeiting barrier of tobacco products. Utility Model Content

[0003] The purpose of this utility model is to provide a self-adhesive anti-counterfeiting label for tobacco. This utility model, through the collaborative design of a multi-level anti-counterfeiting structure, combines the multi-area anti-counterfeiting mark of the top coating with the transfer-type anti-counterfeiting feature of the backing layer to form a comprehensive and difficult-to-imitate anti-counterfeiting system. It can effectively prevent the label from being illegally transferred and reused, and greatly improve the anti-counterfeiting reliability of tobacco products. At the same time, the structural design is reasonable and adaptable to the usage scenarios of tobacco packaging, and has high practical value and promotion significance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tobacco-specific self-adhesive anti-counterfeiting label, comprising a label body, the label body comprising, from top to bottom, a top coating layer, a face paper layer, an adhesive backing layer, and a release film layer, wherein the top coating layer is provided with a first anti-counterfeiting graphic area, a hot stamping area, and a fluorescent graphic area, and the adhesive backing layer is provided with a second anti-counterfeiting graphic area; when the label body is peeled off after being used, the second anti-counterfeiting graphic area is transferred to the adhered item.

[0005] To further optimize this utility model, the following technical solutions may be preferred:

[0006] Preferably, the label body has a fold line in the middle, which divides the label body into upper and lower areas, and the hot stamping area is located in the middle of the lower area; the fold line adopts a combination of crease and dotted line structure, the crease depth is 1 / 2 of the thickness of the face paper layer, and the dotted line spacing is set to 2mm, so that the label can maintain a 90° right angle after folding and is not easy to spring back.

[0007] Preferably, the second anti-counterfeiting graphic area is a uniformly distributed and independent anti-counterfeiting pattern unit.

[0008] Preferably, a silicone oil layer is provided between the adhesive layer and the release film layer; the release film layer is a double-sided silicone-coated PET release film, and the face paper layer is an aluminum foil cloth layer composed of polyester and aluminum foil.

[0009] Preferably, the fluorescent graphic area includes a fluorescent anti-counterfeiting code located at the bottom of the front of the label body and a fluorescent image area distributed on the front of the label body. The fluorescent image area includes multiple unit fluorescent images, and the multiple unit fluorescent images face different directions.

[0010] Preferably, the face paper layer is 80g partial bare silver self-adhesive paper with a reserved base, and the release film layer is 80g glassine backing paper.

[0011] Preferably, the hot stamping area is provided with a laser holographic pattern.

[0012] The tobacco-specific self-adhesive anti-counterfeiting label provided by this utility model, through multi-level anti-counterfeiting design and structural optimization, has the following significant beneficial effects:

[0013] (1) A multi-dimensional anti-counterfeiting system enhances anti-counterfeiting reliability. The label forms a three-dimensional anti-counterfeiting network through the first anti-counterfeiting graphic area of ​​the top coating, the hot stamping area, the fluorescent graphic area, and the second anti-counterfeiting graphic area of ​​the adhesive backing layer. Among them, the laser holographic pattern in the hot stamping area, combined with the multi-directionally distributed unit fluorescent images in the fluorescent graphic area, forms an intuitive visual anti-counterfeiting mark; while the characteristic of the second anti-counterfeiting graphic area being transferred to the adhered item after being peeled off achieves the anti-counterfeiting effect of "one-time pasting, permanent trace", effectively preventing the label from being completely transferred and reused. This combination of "explicit + implicit" and "static + dynamic" significantly increases the difficulty of counterfeiting and meets the high-security anti-counterfeiting requirements of tobacco products.

[0014] (2) Optimized structural design enhances ease of use and stability. The fold line in the middle of the label adopts a combination of embossing and dotted lines. The precise design of the embossing depth and the spacing of the dotted lines ensures that the label can stably maintain a 90° right angle after folding. This facilitates adhesion to special structural parts of tobacco packaging (such as the folded edge of the box) and improves the tightness of the fit between the label and the packaging. At the same time, the fold line divides the label into upper and lower areas, concentrating key anti-counterfeiting information such as the hot stamping area in the lower area, making it easier for consumers to quickly identify and verify, thus optimizing the user's anti-counterfeiting verification experience.

[0015] (3) Material and process compatibility ensures label performance stability. The face paper layer uses a polyester and aluminum foil composite aluminum foil cloth layer or 80g partial-background plain silver self-adhesive paper, which has good scratch resistance and printability, and can stably carry various anti-counterfeiting graphic information. The release film layer uses double-sided silicone-coated PET release film or 80g glassine backing paper. With the addition of the backing adhesive layer and silicone oil layer, it not only ensures the stability of the label during storage and transportation, but also ensures smooth peeling and firm adhesion when labeling. The reasonable combination of materials enables the label to maintain stable performance in complex environments such as humidity and high temperature, extending the effective period of anti-counterfeiting effect.

[0016] (4) Enhanced detail design improves anti-counterfeiting complexity and identifiability. The fluorescent graphic area, through the bottom fluorescent anti-counterfeiting code and the multi-directional fluorescent images distributed on the front, presents rich anti-counterfeiting information under ultraviolet light, which is convenient for professionals to check with equipment and provides consumers with a simple verification method. The independent anti-counterfeiting pattern units in the second anti-counterfeiting graphic area are evenly distributed, making it easier to identify traces after transfer and further eliminating the possibility of local tampering. These detailed designs enhance the complexity of anti-counterfeiting while taking into account the convenience of anti-counterfeiting verification, balancing the needs of professionals and the general public.

[0017] In summary, this utility model, through integrated innovation of anti-counterfeiting technology, refined structural design, and scientific selection of materials, constructs a highly secure and reliable self-adhesive anti-counterfeiting solution suitable for tobacco products. It can effectively curb the circulation of counterfeit and shoddy products and provide consumers and regulatory authorities with convenient and accurate anti-counterfeiting verification methods, thus possessing significant practical value and market application prospects.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-7 As shown, this utility model discloses a self-adhesive anti-counterfeiting label specifically for tobacco products, such as... Figure 1 As shown (the overall structure of the label can be illustrated with reference to the attached diagram), the label body 1 includes a top coating layer 11, a face paper layer 10, an adhesive backing layer 9, and a release film layer 8 arranged sequentially from top to bottom. Each layer is tightly bonded together through a composite process to form an overall structure with uniform thickness.

[0028] Top Coating 11 Structure Design: The top coating 11 serves as the surface anti-counterfeiting carrier of the label, integrating the first anti-counterfeiting graphic area 4, the hot stamping area 2, and the fluorescent graphic area. The first anti-counterfeiting graphic area uses high-precision printing technology to print the brand logo and anti-counterfeiting code, ensuring clear graphics and resistance to wear. The hot stamping area 2 is located in the middle of the lower part of the label (in conjunction with the fold line design), employing laser holographic hot stamping technology. The hot stamping pattern 3 is a tobacco-specific anti-counterfeiting texture that exhibits a dynamic light-changing effect under light, allowing for direct visual identification of authenticity.

[0029] The fluorescent graphic area consists of two parts: First, the fluorescent anti-counterfeiting code 13 located at the bottom of the front of the label. Printed with invisible fluorescent ink, it is invisible under natural light and requires exposure to a 365nm ultraviolet lamp to become visible. This code is linked to the tobacco product's production, logistics, and sales information. By scanning this code, consumers, regulatory authorities, or company personnel can obtain detailed product information, including production date, batch number, raw material source, and sales channels. This enables traceability management of the entire product process from production to sales, effectively combating counterfeit and substandard products and cross-selling. Second, the fluorescent image area 12 distributed on the front of the label consists of multiple unit fluorescent images. Each unit image faces different directions (e.g., 0°, 90°, 180°, 270°, etc.), forming an irregularly distributed matrix of fluorescent patterns, further enhancing the complexity of optical anti-counterfeiting.

[0030] Optimized label structure: The label body 1 features a fold line 5 in the center. This fold line 5 employs a combination of crease and dotted line techniques, with the crease depth being half the thickness of the face paper layer and the dotted line spacing set at 2mm. This structure allows the label to fold upwards 90° along the fold line while maintaining a stable right angle and preventing springback. It adapts to the folded edge structure of tobacco packaging boxes, improving the fit between the label and the packaging. The fold line divides the label into upper and lower sections, with the hot stamping area concentrated in the middle of the lower section, facilitating quick location of key anti-counterfeiting information for consumers.

[0031] Adhesive backing and transfer anti-counterfeiting design: The adhesive backing uses a high-viscosity hot melt adhesive, on which a second anti-counterfeiting graphic area 6 is printed. This area consists of evenly distributed independent anti-counterfeiting pattern units 7 (such as miniature tobacco leaf patterns, random textured dot matrix, etc.), each unit being uniquely identified through variable data printing technology. When the label is affixed to the tobacco packaging, if it is forcibly torn off, the second anti-counterfeiting graphic area of ​​the adhesive backing will be completely transferred to the packaging surface, forming an indelible residue, effectively preventing the label from being reused as a whole.

[0032] A silicone oil layer is also provided between the adhesive layer and the release film layer. The silicone oil layer adopts a uniform coating process to ensure that the peel force between the release film and the adhesive layer is stable at 5-8N / 25mm. This facilitates the efficient operation of automated labeling equipment and prevents the labels from peeling off during storage.

[0033] Material selection and performance assurance: Two preferred options can be selected for the face paper layer: one is an aluminum foil cloth layer composed of polyester and aluminum foil, which has good corrosion resistance and metallic texture, and improves the durability of the label; the other is 80g partial bare silver self-adhesive paper, which has a smooth surface and is suitable for high-precision printing, reducing production costs.

[0034] Two release film layer options are available: If aluminum foil cloth is used as the face paper, double-sided silicone-coated PET release film is selected, which has excellent high temperature resistance and is suitable for high-speed printing processes; if plain silver self-adhesive paper is used, 80g glassine backing paper is selected as the release film, which has good stiffness and release stability.

[0035] Through the combination design of the above structure and materials, this utility model achieves the functions of "multi-layer anti-counterfeiting, one-time pasting, permanent trace, and convenient identification", meeting the tobacco industry's requirements for high security and high reliability of anti-counterfeiting labels, while taking into account production adaptability and consumer user experience.

[0036] Detailed design for each structural layer:

[0037] Top Coating: The top coating is located on the top layer of the label and mainly serves a protective and decorative function. It uses a transparent material with high abrasion resistance and chemical corrosion resistance, such as a composite coating material of polyurethane acrylate (PUA) and nano-silica. The top coating includes a first anti-counterfeiting graphic area, a hot stamping area, and a fluorescent graphic area. The first anti-counterfeiting graphic area is printed with fine brand logos and complex textures using micro-engraving or high-precision printing technology. These graphic information are clearly visible under ordinary light and have high recognizability. The hot stamping area uses laser holographic hot stamping technology. The stamped pattern not only has a metallic luster but also exhibits dynamic optical effects under different angles of light, such as rainbow effects and diffraction stripes, greatly improving the label's anti-counterfeiting performance and aesthetics. The fluorescent graphic area includes a fluorescent anti-counterfeiting code located at the bottom of the front of the label and fluorescent image areas distributed on the front of the label. The fluorescent anti-counterfeiting code is printed with special fluorescent ink, emitting a specific color of fluorescence under ultraviolet light. This fluorescent code is unique and can be read and verified using professional equipment. The fluorescent image area consists of multiple unit fluorescent images, which face different directions and are printed with fluorescent inks of different colors. Under ultraviolet light, they form a unique fluorescent pattern matrix, further enhancing the anti-counterfeiting effect of the label.

[0038] Face Paper Layer: As the main carrier layer of label information, the face paper layer can be made of different materials depending on actual needs. As mentioned earlier, a composite material made of high-strength polyester fiber and special additives can be used to achieve a tear-resistant backing function. Simultaneously, to meet printing requirements, the surface of the face paper layer undergoes special treatment, exhibiting excellent ink absorption and printability, ensuring the smooth implementation of full-color printing processes. When 80g partial backing plain silver self-adhesive paper is selected as the face paper layer, its smooth and flat surface provides excellent display of printed patterns, and the partial backing design further enhances anti-counterfeiting performance. If a polyester-aluminum foil composite layer is used as the face paper layer, this material has excellent barrier properties, effectively preventing interference from the external environment on the label information, while the metallic texture of the aluminum foil also enhances the overall quality of the label.

[0039] Backing Layer: The backing layer uses a specially formulated adhesive with moderate tack, ensuring the label adheres firmly to the tobacco packaging during normal use while allowing the second anti-counterfeiting graphic area to be completely transferred to the adhered item upon removal. The adhesive formulation is as follows: the main resin is styrene-butadiene-styrene block copolymer (SBS), accounting for 30%-40% of the total adhesive mass; the tackifying resin is terpene phenolic resin, accounting for 25%-35%; the softener is naphthenic oil, accounting for 15%-25%; and appropriate amounts of antioxidants, plasticizers, and other additives are added to improve the stability and aging resistance of the adhesive. The coating process of the backing layer uses high-precision coating equipment to ensure that the adhesive is evenly coated on the back of the face paper layer, with the coating thickness controlled between 15μm and 25μm.

[0040] Release film layer: Located at the bottom of the label, the release film layer protects the adhesive layer, preventing contamination and premature curing of the adhesive during storage and transportation. The release film layer can be made of double-sided silicone-coated PET release film or 80g glassine paper. Double-sided silicone-coated PET release film offers excellent high-temperature resistance and release effect, making it suitable for high-speed printing and automated labeling processes. 80g glassine paper provides high stiffness and good flatness, effectively preventing labels from sticking together during winding, and is relatively inexpensive. A silicone oil layer is also placed between the release film layer and the adhesive layer. The main component of the silicone oil layer is dimethyl silicone oil, which is formed into a thin film with a thickness of 0.5μm-1μm through a uniform coating process. This further reduces the peel force between the release film layer and the adhesive layer, ensuring that the label can be easily peeled off during use.

[0041] Application Scenarios: This utility model of tobacco-specific self-adhesive anti-counterfeiting labels is mainly used in the tobacco industry and can be widely affixed to cigarette boxes, cigarette packs, and other tobacco product packaging. During the tobacco product manufacturing process, affixing these anti-counterfeiting labels to product packaging effectively prevents counterfeiting. Consumers can determine the authenticity of tobacco products by observing the label's appearance and verifying anti-counterfeiting information (such as scanning QR codes or viewing fluorescent graphics). For tobacco companies, the one-code-one-label traceability function allows for real-time monitoring of product production, logistics, and sales, facilitating product quality management and market regulation. In combating counterfeit tobacco products, regulatory authorities can quickly and accurately identify counterfeit products by verifying the label's anti-counterfeiting information, maintaining market order and protecting consumer rights. Furthermore, due to the label's unique retention technology and difficult-to-copy anti-counterfeiting features, companies can leverage these characteristics to gain an advantageous position in negotiations should infringement occur, effectively protecting their brand image and economic interests.

[0042] In addition, this product has the following advantages: First, after the self-adhesive anti-counterfeiting label paper is pasted and a backing is left, the label paper is not easy to tear, preventing the label from being reused and ensuring it can only be used once, greatly reducing the possibility of counterfeiting; second, after the self-adhesive label is pasted, there is residue after the first application, but no residue remains after re-application; third, if reused on a box, the residue of the bottom pattern cannot be completely overlapped, providing anti-counterfeiting functionality; fourth, the backing paper of the new self-adhesive anti-counterfeiting label can be personalized with patterns printed according to customer requirements, making the label difficult to completely peel off after pasting. Moreover, current self-adhesive anti-counterfeiting labels on the market do not have a backing paper; they are just a completely transparent film. After the self-adhesive label is pasted, the film is simply pasted in place, resulting in weak anti-counterfeiting functionality. This label solves the problem of reusing labels for counterfeiting. At the same time, the label backing paper is designed with patterns that match the customer's product and achieves flexible printing. By using this new type of self-adhesive anti-counterfeiting label, both anti-counterfeiting and easy-to-tear, non-reusable effects are achieved.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
