Detailed Implementation
[0028] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0029] The inventors, through analysis of existing technologies, discovered that electronic tags operate in complex environments and may come into contact with moisture. If an electronic tag becomes damp or water gets inside, its internal electronic components may experience short circuits, corrosion, and other problems, leading to a sharp drop in reading distance or even complete failure. Current anti-counterfeiting methods mostly rely on one-time laser holograms or serial number QR codes, whose information is static, easily copied, and cannot withstand high-resolution scanning and secondary printing attacks.
[0030] Reference Figures 1-5 The present invention illustrates an anti-counterfeiting and waterproof electronic tag, comprising a first waterproof coating layer 100, an antenna layer 200, a substrate layer 300, and a second waterproof coating layer 400 stacked sequentially.
[0031] The antenna layer 200 is provided with a chip 700; the second waterproof coating layer 400 is provided with a bridging layer 500 on top, and the antenna layer 200 is connected to the bridging layer 500 through the bridging conduction point 600 to form a circuit;
[0032] The substrate layer 300 is provided with a plurality of anti-counterfeiting additives 800, wherein the anti-counterfeiting additives 800 are one or more of polygons, rectangles and rings, and the first waterproof coating layer 100 is provided with a coding area 900.
[0033] It should be noted that by employing special encapsulation materials and processes, the internal circuitry of the electronic tag is sealed, effectively resisting moisture erosion. This ensures stable operation of the electronic tag in various humid environments, extends its service life, and guarantees the reliability of information identification. By using various anti-counterfeiting additives 800, counterfeiting and tampering of products by criminals can be effectively prevented, providing a new and reliable solution for product anti-counterfeiting management. The anti-counterfeiting waterproof electronic tag proposed in this application has a multi-layer composite structure, with a first waterproof coating layer 100, an antenna layer 200, a substrate layer 300, and a second waterproof coating layer 400 stacked sequentially from top to bottom. The antenna layer 200 integrates a chip 700, and the top of the second waterproof coating layer 400 has a bridging layer 500. The antenna layer 200 is connected to the bridging layer 500 through a bridging conduction point 600 to form a complete circuit loop for electronic signal transmission. Several anti-counterfeiting additives 800 are distributed within the substrate layer 300, such as… Figures 3-4 As shown, these additives include rectangular anti-counterfeiting additive 801, polygonal anti-counterfeiting additive 802, and circular anti-counterfeiting additive 803, which can play an anti-counterfeiting identification role; the first waterproof coating layer is provided with a coding area for information identification.
[0034] The double-layer waterproof coating forms a dual protective barrier, effectively isolating moisture and humidity from intrusion and ensuring stable use of the label in complex environments such as dampness and water immersion. The antenna layer 200 is connected to the bridge layer 500 at the top of the second waterproof coating layer 400 through the bridge conduction point 600 to form a complete circuit. Combined with the integrated chip 700, it can stably realize electronic signal transmission and identification functions, ensuring reliable electronic reading and writing performance of the label. The rectangular anti-counterfeiting additives 801, polygonal anti-counterfeiting additives 802, and circular anti-counterfeiting additives 803 distributed in the substrate layer 300, combined with the inkjet printing area design of the first waterproof coating layer 100, construct a dual anti-counterfeiting system, which greatly increases the difficulty of counterfeiting. At the same time, the inkjet printing area can also flexibly carry key information such as product traceability and identity verification. The overall structure is compact and highly integrated, taking into account waterproof durability, electronic identification and anti-counterfeiting security, and is applicable to a wide range of scenarios.
[0035] In the embodiments of this application, addressing the shortcomings of existing electronic tags that are easily damaged by moisture and have poor anti-counterfeiting measures due to easy scanning of anti-counterfeiting marks, this application proposes an anti-counterfeiting waterproof electronic tag, comprising a first waterproof coating layer 100, an antenna layer 200, a substrate layer 300, and a second waterproof coating layer 400 stacked sequentially; the antenna layer 200 is provided with a chip 700; the second waterproof coating layer 400 has a bridging layer 500 on top, and the antenna layer 200 is connected to the bridging layer 500 through a bridging conduction point 600 to form a circuit; the substrate layer 300 is provided with a plurality of anti-counterfeiting additives 800, which are one or more of polygons, rectangles, and rings; the first waterproof coating layer 100 is provided with a coding area 900. By setting a double-layer waterproof coating layer, the protective performance of the electronic tag is guaranteed; by adding a plurality of anti-counterfeiting additives 800, and adding a plurality of different anti-counterfeiting additives 800 in a random manner, the possibility of duplication is reduced, thus ensuring the anti-counterfeiting performance of the electronic tag.
[0036] The following will further describe an anti-counterfeiting and waterproof electronic tag in this exemplary embodiment.
[0037] In one embodiment of this application, the first waterproof coating layer 100 is an opaque film.
[0038] It should be noted that the first waterproof coating layer 100 is made of an opaque film material. While achieving waterproof protection, it can effectively cover key structures inside the label, such as the antenna layer 200, chip 700, and bridging connection point 600, preventing the internal circuit layout and connection method from being directly observed. This reduces the risk of the label's core structure being reverse-engineered or counterfeited, further enhancing anti-counterfeiting security. At the same time, the opaque nature also protects the inkjet printing area on its surface. It can prevent the inkjet printing information from fading or blurring due to direct sunlight and also prevent the inkjet printing content from being easily viewed. Especially when the inkjet printing is an invisible mark, the opaque film can further ensure that the information cannot be read without authorization, thus meeting multiple requirements of waterproofing, structural confidentiality, and inkjet printing information protection.
[0039] In one embodiment of this application, the first waterproof coating layer 100 is a black PI film or a polymer film made of light-shielding coated PET material.
[0040] It should be noted that both the black PI film and the light-shielding coated PET polymer film possess excellent waterproof performance and structural stability. The black PI film is also resistant to high temperatures and chemical corrosion, maintaining its shape and function in complex environments such as high and low temperatures and humidity, effectively preventing moisture intrusion. The light-shielding coated PET achieves a high light-shielding rate through a special coating, blocking external light from penetrating. Both materials can cover the core structures inside the label, such as the antenna layer 200, chip 700, and bridging conduction points 600, preventing the circuit layout from being directly observed, reducing the risk of reverse disassembly and counterfeiting. At the same time, they can also protect the inkjet printing area on the surface, preventing the inkjet information from fading due to direct sunlight or being viewed by unauthorized personnel. In addition to ensuring waterproof function, this further enhances the anti-counterfeiting security and long-term durability of the label.
[0041] In one embodiment of this application, the first waterproof coating layer 100 is a polymer film made of PET, TPU, EVA or PP film.
[0042] It should be noted that when the first waterproof coating layer 100 is transparent, it can be made of polymer film such as PET, TPU, EVA, or PP. These materials all possess excellent waterproof and moisture-proof properties, effectively preventing external moisture and humidity from penetrating the label and providing reliable protection for core components such as the antenna layer 200 and chip 700. Among them, PET film has strong stiffness and weather resistance, making it suitable for scenarios with high requirements for morphological stability; TPU film has good flexibility and tensile strength, adapting to curved or easily bendable surfaces; EVA film has good adhesion, adhering tightly to the underlying structure to reduce gaps; and PP film has excellent chemical corrosion resistance, capable of withstanding certain special environments. Simultaneously, all four polymer films are compatible with the information printing requirements of the coding area on the first waterproof coating layer 100, without affecting the clarity of the coding, and protecting the coding information from detachment due to friction and environmental erosion. While ensuring waterproof functionality, it also considers the label's adaptability to various scenarios and its practical durability.
[0043] In one embodiment of this application, the anti-counterfeiting additive 800 is a fluorescent material, and the anti-counterfeiting additive 800 is randomly scattered on the substrate layer 300.
[0044] It should be noted that the anti-counterfeiting additive 800 is made of fluorescent material and is evenly distributed within the substrate layer in a random, scattered manner. This not only does not damage the structural stability of the substrate layer 300 but also creates a unique distribution pattern. This fluorescent material emits noticeable fluorescence under specific light sources such as ultraviolet light. Combined with its irregular scattered state, it forms a visual anti-counterfeiting feature that is difficult to replicate. Counterfeiters not only find it difficult to accurately match the optical properties of the fluorescent material but also cannot replicate the random scattered position and density of the additive, significantly raising the anti-counterfeiting threshold of the label. Furthermore, this design, embedded within the substrate layer, prevents the additive from falling off due to external friction and wear, ensuring the long-term effectiveness of the anti-counterfeiting function.
[0045] In one embodiment of this application, the fluorescent material emits fluorescence under ultraviolet light with a wavelength of 365nm-405nm.
[0046] It should be noted that fluorescent materials are only excited and emit clearly visible fluorescence under ultraviolet light with wavelengths between 365nm and 405nm. This wavelength range is a commonly used standard band in the field of anti-counterfeiting detection. The corresponding ultraviolet detection equipment is readily available and easy to operate. During detection, simply irradiate the label substrate layer with an ultraviolet lamp that conforms to this wavelength range, and you can quickly and preliminarily identify the authenticity of the label by observing whether a fluorescence reaction occurs. Moreover, this fluorescence reaction is highly targeted and does not appear under ordinary natural light or other wavelength light sources. This avoids misidentification in non-detection scenarios and further enhances the concealment and reliability of anti-counterfeiting measures. Combined with the random distribution characteristics of additives, it can form an anti-counterfeiting label that is more difficult to counterfeit.
[0047] In one embodiment of this application, the substrate layer 300 is paper-based, and the basis weight of the substrate layer 300 is 30-70 g / m². 2 .
[0048] It should be noted that the substrate layer 300 is made of paper-based material, and its basis weight is controlled between 30-70 g / m². 2 Within this weight range, the paper base combines lightweight design with moderate structural strength. This avoids the problem of excessively thick material causing the label to become bulky and affecting its application flexibility, while also preventing issues such as fragility and inability to support the upper and lower layers due to excessive thinness. Furthermore, the paper base material has good compatibility, stably accommodating randomly scattered anti-counterfeiting additives, and can tightly adhere to the upper antenna layer 200 and the lower second waterproof coating layer 400 without affecting the function of each layer. It also reduces overall production costs while ensuring the label's basic support function, making it suitable for mass production and everyday use.
[0049] In one embodiment of this application, the antenna layer 200 is prepared by aluminum etching or silver paste printing process;
[0050] When prepared using a silver paste printing process, the bridging layer 500 and the antenna layer 200 are located on the same side of the substrate layer 300.
[0051] It should be noted that the antenna layer 200 can be prepared by either aluminum etching or silver paste printing. Aluminum etching can ensure that the antenna has high-precision circuitry and stable conductivity, making it suitable for scenarios with high requirements for signal transmission quality. Silver paste printing is more flexible and less expensive, and is easier to process and form on the surface of flexible substrates such as paper.
[0052] When using silver paste printing to prepare the antenna layer 200, the bridging layer 500 and the antenna layer 200 should be placed on the same side of the substrate layer 300. This layout simplifies the label lamination process, avoids signal loss or short circuit risks caused by opposite-side connections, and ensures that the antenna layer 200 and the bridging layer 500 are efficiently connected through the bridging connection point 600 to form a stable and complete circuit loop without affecting the electronic reading and writing function of the label.
[0053] In one embodiment of this application, a fiber reinforcement layer is provided on the side of the substrate layer 300 away from the antenna layer. The fiber reinforcement layer is a glass fiber cloth or a polyester fiber mesh, and the thickness of the fiber reinforcement layer is 5-10 μm.
[0054] It should be noted that both fiberglass cloth and polyester fiber mesh have high tensile strength and good toughness, which can specifically improve the structural stability of paper-based substrates and avoid problems such as tearing or deformation of the substrate layer 300 during label application, handling, or bending. At the same time, the ultra-thin design of 5-10μm will not increase the overall thickness and weight of the label, nor will it affect the tight adhesion between the substrate layer 300 and the second waterproof coating layer 400, ensuring that the label maintains its original flexibility and usability, and is compatible with various application scenarios.
[0055] In one embodiment of this application, the chip 700 is wrapped with a protective encapsulation layer, the protective encapsulation layer is made of epoxy resin, and an electromagnetic shielding film is provided between the protective encapsulation layer and the antenna layer 200.
[0056] It should be noted that epoxy resin possesses excellent water resistance, impact resistance, and chemical corrosion resistance, enabling it to tightly encapsulate the chip and effectively isolate it from external moisture, dust, and minor impacts, preventing damage to the chip 700 from environmental factors that could affect its function. Simultaneously, an electromagnetic shielding film is provided between the protective encapsulation layer and the antenna layer 200. This shielding film isolates electromagnetic interference generated during antenna operation and also blocks electromagnetic signals from the external environment from interfering with the chip 700, ensuring stable data reception and transmission and guaranteeing the reliability of the tag's overall electronic identification function.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
