Description

Technical Field

[0001] This utility model belongs to the field of packaging film technology, and in particular relates to an anti-counterfeiting packaging film. Background Technology

[0002] In the modern commodity market, anti-counterfeiting packaging film is crucial for protecting products, safeguarding consumer rights, and upholding corporate brand image. However, with the continuous advancement of counterfeiting techniques, traditional anti-counterfeiting packaging film faces increasing challenges.

[0003] Currently, while common anti-counterfeiting packaging film technologies on the market offer some anti-counterfeiting features, they still have significant shortcomings. For example, traditional single-layer anti-counterfeiting technologies (such as laser holography and electronic supervision codes) have only one level of anti-counterfeiting, making it easy for counterfeiters to replicate surface anti-counterfeiting labels, thus making it difficult for consumers to accurately distinguish between genuine and counterfeit products. Although some multi-layer anti-counterfeiting packaging films enhance anti-counterfeiting performance, they suffer from complex structures and high production costs, hindering their widespread application in various product packaging. Furthermore, some existing anti-counterfeiting packaging films do not adequately consider preventing consumers from being misled in their design, allowing counterfeiters to confuse consumers by creating similar fake anti-counterfeiting labels.

[0004] Therefore, it is essential to invent an anti-counterfeiting packaging film. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an anti-counterfeiting packaging film, including an AL film, an OPP film, a VC film, a fake anti-counterfeiting label, a cover anti-counterfeiting sheet, and an anti-counterfeiting QR code. The AL film, OPP film, and VC film are composited together. The OPP film has a fake anti-counterfeiting label printed on it. The AL film has an anti-counterfeiting QR code and is composited with the cover anti-counterfeiting sheet.

[0006] Preferably, the anti-counterfeiting film is laminated between the AL film and the OPP film, and the anti-wear film laminated on the surface of the OPP film covers the surface of the fake anti-counterfeiting label.

[0007] Preferably, the counterfeit anti-counterfeiting label printed on the OPP film and the anti-counterfeiting QR code printed and engraved on the AL film surface are not on the same straight line, but are offset.

[0008] Preferably, the anti-counterfeiting cover film composited on the surface of the AL film covers the surface of the anti-counterfeiting QR code, wherein the anti-counterfeiting cover film is a rectangular sheet structure made of thermally sensitive material.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This invention combines AL film, OPP film, and VC film. The AL film has excellent barrier properties, effectively preventing moisture and oxygen, and protecting the internal products. The OPP film enhances the mechanical strength of the packaging film, improving its tensile and tear resistance. The VC film further enhances the barrier properties or provides other additional functions. The combination of the three makes the packaging film have both excellent protective and mechanical properties, suitable for various product packaging needs.

[0011] This invention features a misaligned design where the counterfeit anti-counterfeiting label printed on the OPP film is offset from the anti-counterfeiting QR code on the AL film surface. This design makes it difficult for counterfeiters to accurately replicate both genuine and counterfeit anti-counterfeiting information simultaneously, increasing the difficulty and cost of forgery. Consumers must use specific methods (such as temperature triggering) to detect the genuine anti-counterfeiting QR code, effectively avoiding being misled by counterfeit labels and improving the reliability and concealment of anti-counterfeiting measures.

[0012] The anti-counterfeiting cover on the surface of this AL film is made of a thermosensitive material. At room temperature, it covers the anti-counterfeiting QR code, preventing it from being easily detected and copied. When the packaging film is subjected to a specific temperature operation (such as heating), the thermosensitive material changes, revealing the anti-counterfeiting QR code, which consumers can scan to verify authenticity. This dynamic anti-counterfeiting method increases the fun and technological appeal of anti-counterfeiting, while utilizing the temperature-triggered characteristics to improve the targeting and confidentiality of anti-counterfeiting, making it difficult for counterfeiters to crack.

[0019] As attached Figure 1 To be continued Figure 2 As shown:

[0020] This utility model provides an anti-counterfeiting packaging film, comprising an AL film 1, an OPP film 2, a VC film 3, a fake anti-counterfeiting label 4, a cover anti-counterfeiting sheet 5, and an anti-counterfeiting QR code 6. The AL film 1, OPP film 2, and VC film 3 are composited together. The fake anti-counterfeiting label 4 is printed on the OPP film 2. The anti-counterfeiting QR code 6 is provided on the AL film 1, and the cover anti-counterfeiting sheet 5 is composited thereon.

[0021] Furthermore, the anti-counterfeiting cover 5 is made of a 50-100μm thick thermosensitive polymer material, in a rectangular sheet structure, and is laminated between the front of the AL film 1 and the OPP film 2 by uniformly coating with hot melt adhesive. In practice, an anti-counterfeiting QR code 6 is first printed on the front of the AL film 1, then the anti-counterfeiting cover 5 is precisely aligned and placed over the QR code surface. Subsequently, the AL film 1 and OPP film 2 are pressed together using a dry lamination process, sandwiching the anti-counterfeiting cover 5 between the two layers. Simultaneously, a counterfeit anti-counterfeiting label 4 is printed on the surface of the OPP film 2 using gravure printing, and a 20-30μm thick PET abrasion-resistant film is laminated onto the surface of the counterfeit anti-counterfeiting label 4. This abrasion-resistant film is bonded to the OPP film 2 with water-based adhesive, effectively resisting friction damage to the counterfeit anti-counterfeiting label 4 and ensuring its long-term clarity.

[0022] Furthermore, the counterfeit anti-counterfeiting label 4 printed on the surface of OPP film 2 and the anti-counterfeiting QR code 6 formed on the surface of AL film 1 by laser engraving or gravure printing are misaligned in planar position. Specifically, the two are offset in the horizontal or vertical direction, and the misalignment path is irregular. For example, the counterfeit anti-counterfeiting label 4 can be set in the upper left corner of OPP film 2, while the anti-counterfeiting QR code 6 is set in the lower right corner of AL film 1. Through this asymmetrical misaligned layout, it is difficult for counterfeiters to deduce the location of the genuine anti-counterfeiting information by observing the surface, further enhancing the concealment of anti-counterfeiting measures.

[0023] Furthermore, the anti-counterfeiting cover 5 laminated on the surface of the AL film 1 has a rectangular structure, the size of which is adapted to the anti-counterfeiting QR code 6, typically with a side length 5-8mm longer than the edge of the QR code, to completely cover the anti-counterfeiting QR code 6. The anti-counterfeiting cover 5 is made of a thermosensitive resin material with a temperature change range of 35-60℃. At room temperature, it is opaque, obscuring the QR code 6. When the external temperature reaches a set threshold (e.g., 50℃), the anti-counterfeiting cover 5 gradually becomes transparent, revealing the anti-counterfeiting QR code 6 underneath. This thermosensitive material has reversible color-changing properties, and can return to its obscuring state after the temperature recovers.

[0024] The working principle is as follows: First, when consumers come into contact with the packaging, they first observe the fake anti-counterfeiting label 4 on the surface of the OPP film 2, which is protected by an anti-abrasion film. This label, as a visible "fake anti-counterfeiting information", is used to confuse counterfeiters and make them mistakenly focus their copying efforts on the fake label.

[0025] Next, when consumers need to verify the authenticity of the product, a specific temperature (such as 50°C) needs to be applied to the area covered by the anti-counterfeiting film 5 in the packaging film. Since the anti-counterfeiting film 5 is made of a thermosensitive resin material with a temperature change range of 35-60°C, its molecular structure changes after being heated, and it gradually changes from an opaque state at room temperature to a transparent state.

[0026] Then, after the anti-counterfeiting film 5 is made transparent, the anti-counterfeiting QR code 6 on the surface of the AL film 1 underneath is revealed. Consumers can scan the QR code with their mobile phones or other devices to access the back-end verification system, obtain the product's true information (such as production batch, place of origin, anti-counterfeiting code, etc.), and complete the authenticity verification.

[0027] Finally, when the temperature returns to normal, the molecular structure of the heat-sensitive material covering the anti-counterfeiting film 5 is restored, and it becomes opaque again, covering the anti-counterfeiting QR code 6 once more, preventing wear and tear or malicious copying caused by long-term exposure, and ensuring the sustainability of the anti-counterfeiting function.

[0028] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
