Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of packaging anti-counterfeiting, and particularly relates to a sealing box anti-counterfeiting method applying holographic interference technology. BACKGROUND
[0002] With the vigorous development of global logistics industry and e-commerce, the demand for anti-counterfeiting technology of commodity packaging is also continuously improving. During the transportation, storage and distribution of logistics packages and commodities, they face the risk of tampering, counterfeiting and even theft. This not only damages the interests of consumers, but also affects the brand image and business reputation of enterprises. Most of the anti-counterfeiting technologies on the current market, such as two-dimensional codes, anti-counterfeiting labels and sealing box anti-counterfeiting tapes, provide anti-counterfeiting protection to some extent, but also have significant limitations. For example, two-dimensional codes and anti-counterfeiting labels can be easily counterfeited by photographing or copying technology; and although the sealing box anti-counterfeiting tape has a sealing function, it lacks unique anti-counterfeiting identification characteristics and it is difficult to effectively distinguish the authenticity from the visual perspective.
[0003] Holographic anti-counterfeiting technology has become an important means in the anti-counterfeiting field due to its non-reproducible holographic images and unique optical effects. Holographic patterns have complex structures and high precision, and three-dimensional images are generated with the help of light interference principles. This image can only be seen under specific angles and light, and ordinary scanners or cameras cannot reproduce it.
[0004] Holographic patterns have been widely used in fields such as banknotes, identity cards, credit cards and luxury product packaging. However, the application of holographic technology for anti-counterfeiting sealing has not been widely popularized, especially the design of holographic interference on the surface of tapes and packaging boxes. Combining holographic interference technology with the sealing process is a technical problem that needs to be solved by technical personnel in this field.
[0005] The present application is based on this anti-counterfeiting demand and solves the deficiencies of existing anti-counterfeiting sealing technology through the innovative application of holographic interference technology. Specifically, the present application designs independent holographic patterns on sealing tapes and packaging boxes. During the sealing process, the two patterns interact to form a unique interference pattern. Combining holographic interference technology with the sealing process can significantly improve the anti-counterfeiting effect of logistics packages and provide a new and efficient anti-counterfeiting sealing method for the market. SUMMARY
[0006] The present application aims to provide a sealing box anti-counterfeiting method applying holographic interference technology, which designs independent holographic patterns on sealing tapes and packaging boxes. During the sealing process, the two patterns interact to form a unique interference pattern, which can significantly improve the anti-counterfeiting effect of logistics packages and provide a new and efficient anti-counterfeiting sealing method for the market.
[0007] The application is realized by the following technical scheme: Namely, a sealing box anti-counterfeiting method using holographic interference technology, characterized in that the steps are as follows: 1) A sealing box adhesive tape is made, and the layer structure thereof is, from top to bottom, a release layer, a tape base film, a die coating layer, a first holographic information layer, a transparent protective layer, and a glue layer. A first horizontal marker is processed on one side of all holographic patterns of the first holographic information layer, and a first vertical marker is processed on one side of each holographic pattern of the first holographic information layer, respectively. The first vertical marker and the first horizontal marker are accurately positioned relative to the holographic patterns of the first holographic information layer. 2) The surface of the packaging box is processed by film covering. The layer structure of the packaging box from inside to outside is, in sequence, a box plate, a composite glue layer, a transparent protective layer, a second holographic information layer, a die coating layer, and a film. A second horizontal marker is processed on one side of all holographic patterns of the second holographic information layer, and a first vertical marker is processed on one side of each holographic pattern of the second holographic information layer, respectively. The second vertical marker and the second horizontal marker are accurately positioned relative to the holographic patterns of the first holographic information layer. 3) In the sealing process, the markers corresponding to the surface of the sealing box adhesive tape and the surface of the packaging box are observed, so that the first holographic patterns on the surface of the sealing box adhesive tape are accurately positioned and pasted with the second holographic patterns on the surface of the packaging box. The first holographic patterns and the second holographic patterns form interference holographic patterns.
[0008] The design of the first holographic patterns on the sealing box adhesive tape and the second holographic patterns on the packaging box in the application is realized by a specific coherent pattern design (pre-encoding pattern design), so that a unique visual interference holographic pattern is formed after sealing. The interference holographic pattern exhibits dynamic optical effects when the illumination or observation angle changes.
[0009] The above-mentioned "specific coherent pattern design" refers to the fact that the first holographic patterns and the second holographic patterns are specially designed to be a pair of matching and interrelated structures. They are not random but are accurately designed so that they can produce specific and dynamic visual effects through optical interference (mainly the Moire effect) when they overlap.
[0010] The above-mentioned "pre-encoding pattern design" refers to the fact that the matching relationship that can produce specific dynamic effects is designed through complex calculation before production, and the expected anti-counterfeiting information is "encoded" into the structures of the two independent patterns. Only when the correct two patterns (adhesive tape and packaging box) are combined in the correct relative position, the "encoding" will be "decoded", and a unique dynamic interference holographic pattern will be displayed, so as to achieve the purpose of anti-counterfeiting and verification of authenticity.
[0011] The design of the interference holographic pattern is customized according to brand requirements and product characteristics, so that the interference pattern formed after sealing the box is unique, and the sealing pattern of different products is not the same, and the flexibility of anti-counterfeiting is increased.
[0012] After the sealing tape is opened, the holographic patterns on the sealing tape and the surface of the packaging box cannot be restored to the relative positions before sealing, so that the third holographic pattern permanently disappears after the tape is opened, preventing the sealing tape from being used again, and the principle is as follows: Because the first holographic pattern and the second holographic pattern need to be accurately positioned longitudinally and transversely, the tape is displaced longitudinally and transversely after being opened, and the interference of the deformation of the tape film, the interference of the glue bonding, etc., cannot be accurately positioned again, and the anti-counterfeiting function is invalid.
[0013] The sealing tape of the present application is made of transparent material, so that the light can pass through the sealing tape and interfere with the second holographic pattern on the surface of the packaging box to form the third holographic pattern.
[0014] The first holographic pattern, the second holographic pattern and the interference holographic pattern of the present application are designed with color holographic pattern.
[0015] The above setting increases the visual recognition of the interference pattern, so that the third holographic pattern shows more obvious color change and anti-counterfeiting effect in the sealed state.
[0016] The present application has the advantages of good product appearance effect and good anti-counterfeiting performance.
[0017] The anti-counterfeiting sealing method of the present application is suitable for product packaging anti-counterfeiting and logistics anti-counterfeiting application requirements, and has the advantages of good anti-counterfeiting effect.
[0018] 1) Independent holographic patterns are designed on the sealing tape and the packaging box, which are independent before sealing, can be adapted independently, can be matched with each other, and have unique function and flexible use; 2) The double holographic pattern design not only enhances the complexity of the pattern, but also improves the difficulty of anti-counterfeiting. The anti-counterfeiting mark in the traditional sealing method is usually limited to single-surface anti-counterfeiting design, while the present technology produces a unique interference holographic pattern after sealing through double holographic pattern design, which provides higher reliability for anti-counterfeiting; 3) The holographic pattern on the sealing tape and the holographic pattern on the packaging box interfere with each other after sealing, forming a new interference holographic pattern. The interference holographic pattern has highly complex optical characteristics and can only be seen under specific angles and light conditions. Moreover, it cannot be copied by ordinary imaging technology due to its optical generation principle. This interference imaging method increases the uniqueness and non-reproducibility of the image, ensuring the anti-counterfeiting effect of the sealing pattern. This dynamic and unique interference image effectively prevents the possibility of imitation or tampering; 4) The interference pattern after sealing exhibits dynamic visual effects under changes in light and viewing angle, making the interference pattern not just a static image, but a dynamic visual image that presents different effects with changes in viewing angle and light source. This design has significant advantages in anti-counterfeiting, as it is difficult for general counterfeiting methods to reproduce this multi-angle optical effect, which can be easily identified by the naked eye. The dynamic optical effect also improves the visual recognition, allowing consumers or logistics staff to quickly confirm whether the packaging has been tampered with; 5) To avoid the pattern being reused or copied, the invention automatically disables the interference pattern after the sealing tape is opened. Once the holographic patterns on the tape and the packaging box surface are torn, the interference pattern disappears, and the double holographic patterns each return to an independent image and cannot be realigned. This self-destructive design not only enhances the anti-counterfeiting effect, but also ensures the non-reusability of the sealing tape, effectively preventing the secondary counterfeiting of the packaging. Traditional sealing tapes can often be reused after being opened, limiting their anti-counterfeiting effect. However, the self-destructive design of the invention ensures the uniqueness and one-time use of the sealing, further enhancing security; 6) To achieve the interference imaging effect, the technology uses transparent materials and process technology as the main material of the sealing tape, allowing light to pass through the tape and enter the holographic pattern, and interfere with the holographic pattern on the packaging box. The transparency of the sealing tape ensures the clarity of the interference pattern, and the optical coherence design of the holographic patterns on the tape and the packaging box ensures that the patterns can produce unique interference effects under light irradiation. This design not only enhances the visual clarity of the interference pattern, but also effectively improves the complexity of the sealing anti-counterfeiting, increasing the difficulty of imitation; 7) The sealing process uses precise alignment design to ensure the completeness and clarity of the interference pattern.
