[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] An image comparison anti-counterfeiting tape comprises a base film layer 1, a printing layer 2, a color layer 3 and an adhesive layer 4 which are arranged in sequence from top to bottom.

[0026] The base film layer 1 is the basic structure of the tape, responsible for supporting the entire tape and ensuring its strength and durability. It uses PET or BOPP film materials as the base film layer, and the thickness of the base film layer is controlled between 15-30 microns.

[0027] Printing layer 2 is formed by printing a QR code and randomly distributed granular dots on base film layer 1. The QR code encodes the product's unique identification information, such as the product number, production date, and batch number, to facilitate traceability and anti-counterfeiting. The randomly distributed granular dots, created using a digital printing press, vary in shape, size, and distribution, creating a unique anti-counterfeiting image. Furthermore, the granular dots are composed of geometric shapes or musical symbols, and the selection and combination of these shapes or symbols are also unique.

[0028] The color layer 3 is located above the printing layer and is used to enhance the visual effect and aesthetics of the tape. A UV-dried color coating is used as the color layer material.

[0029] The adhesive layer 4 is the part of the tape that contacts the packaging or product surface and is responsible for the tape's adhesion function. It uses an environmentally friendly glue with excellent adhesion and removability, ensuring the tape adheres securely to the packaging or product while allowing for easy removal without leaving a trace when needed.

[0030] Preferably, the image comparison anti-counterfeiting tape is further provided with a tear strip at one end of the anti-counterfeiting unit, which makes it easy for consumers to tear off the tape from the packaging or product, thereby improving the convenience and comfort of use.

[0031] Preferably, the image comparison security tape integrates an advanced anti-counterfeiting verification system. This system combines QR code technology with a unique granular dot pattern to create an efficient and reliable anti-counterfeiting verification mechanism.

[0032] Specifically, each QR code on the tape is unique. After consumers scan the QR code, a picture of random granular dots will pop up. Consumers will compare this pattern with the pattern composed of granular dots on the tape. If the images are consistent, it is authentic; otherwise, it means the tape is counterfeit.

[0033] The image is compared to the granular dot pattern of the security tape. Each security unit has a unique granular dot pattern. The random granular dots are generated using a complex encryption algorithm that corresponds one-to-one with the data behind the QR code. The combination of the position, size, and shape of each granular dot creates a visual combination lock that is difficult to replicate.

[0034] The one-to-one correspondence between the QR code and the random dot pattern creates a mutually verified relationship, significantly improving the accuracy and reliability of anti-counterfeiting measures. Furthermore, this image comparison method significantly enhances consumer engagement and trust, allowing them to personally participate in the anti-counterfeiting verification process and intuitively experience the rigor and effectiveness of the product's anti-counterfeiting measures.

[0035] Example 1

[0036] According to this embodiment, an image comparison anti-counterfeiting tape includes a base film layer 1, a printing layer 2, a color layer 3, and an adhesive layer 4. The printing layer is arranged below the base film layer 1, the color layer 3 is coated below the base film layer 1 and the printing layer 2, and the adhesive layer is located below the color layer 3.

[0037] The preparation method of the image comparison anti-counterfeiting tape is as follows:

[0038] The base film layer 1 is a 20-micron-thick BOPP film that is subjected to single-sided corona treatment, with a corona value greater than 38 dynes.

[0039] A QR code and particle image are printed on the corona surface of the BOPP film. The QR code includes the product name, manufacturer, and batch number. The particle image is composed of a combination of triangles of varying colors, numbers, positions, and shapes. The combination of these triangles creates a unique particle image on the tape. The QR code information and the particle image are correlated, with each QR code corresponding to a unique particle image. Each QR code on the tape is also unique and distinct. The printed layer is created using a non-contact digital inkjet printer, with a spacing of at least 1 mm between the QR code and the particles, ensuring no overlap.

[0040] A white color layer 3 is printed under the base film layer 1 and the printing layer 2. The dry coating amount of the white color layer 3 is 2.0 g / m 2 .

[0041] An image acquisition device is used to acquire the two-dimensional code information and the particle image information. After acquisition, the image and the two-dimensional code information are associated, and the associated data information is uploaded to the server.

[0042] Apply pressure-sensitive adhesive on the white color layer 3 to form an adhesive layer 4. The coating amount of the pressure-sensitive adhesive is 30g / m 2 .

[0043] Example 2

[0044] According to this embodiment, an image comparison anti-counterfeiting tape includes a PET base film layer 1, a printing layer 2, a color layer 3, and an adhesive layer 4. The printing layer is arranged below the base film layer 1, the yellow color layer 3 is arranged below the base film layer 1 and the printing layer 2, and the adhesive layer is located below the yellow color layer 3.

[0045] The preparation method of the image comparison anti-counterfeiting tape is as follows:

[0046] The base film layer 1 is a 30-micron-thick PET film, which is subjected to single-sided corona treatment, and the corona value is greater than 38 dynes.

[0047] A QR code and particle image are printed on the corona surface of the PET film. The particle image is a combination of musical notes on a staff. The musical notes have different colors, numbers, positions, and shapes. The combination of the musical notes' appearance creates a unique particle image on the tape. The QR code information and the particle image are correlated, with each QR code corresponding to a unique particle image. Each QR code on the tape is also unique and distinct. Printed layer 2 is formed using a digital printer, with a spacing of greater than 1 mm between the QR code and the musical notes, and no overlap.

[0048] The yellow color layer 3 is printed under the base film layer 1 and the printed layer 2. The dry coating amount of the yellow color layer is 1.5g / m 2 .

[0049] Use an image collector to collect QR code information and particle image information, synchronously associate the collected image with the QR code information, and upload the associated data information to the server.

[0050] Apply pressure-sensitive adhesive on the yellow color layer 3 to form an adhesive layer 4. The coating amount of the pressure-sensitive adhesive is 35g / m 2 .

[0051] Specific usage:

[0052] During use, the image-matching anti-counterfeiting tape is affixed to a corrugated cardboard box via the adhesive layer 4. When a consumer performs anti-counterfeiting authentication, they use their mobile phone to scan the QR code on the tape. This displays an image associated with the QR code and prompts the consumer with the number of scans of the QR code. The consumer compares the particle image on the tape with the image associated with the QR code. If the particle image's appearance and color match the image associated with the QR code, the product is authentic; otherwise, it is considered counterfeit.

[0053] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
