Abstract
Description
Technical Field
[0001] This utility model relates to the field of tape technology, and more particularly to a sealing anti-counterfeiting tape and a double-layer anti-counterfeiting tape structure. Background Technology
[0002] In today's society, counterfeit goods have become a global problem. Driven by profit, counterfeit and shoddy products are rampant in the market, especially luxury goods and tobacco and alcohol products, which have become one of the key targets for criminals to manufacture counterfeit and shoddy goods. This poses a great threat to people's lives and even health and safety, and also causes huge losses to enterprises and society.
[0003] Currently, sanitary napkin sealing tape, also known as quick-release tape, easy-tear tape, or packaging sealing tape, uses PP polypropylene film as its base material. After heating, a pressure-sensitive adhesive emulsion is evenly coated onto the film, forming an adhesive layer ranging from 8μm to 40μm. It is an indispensable packaging material for hygiene products. Using PP as the base material, the tape can be coated in any color according to customer requirements. After applying pressure-sensitive adhesive and drying, it becomes a self-adhesive tape. Company logos and names can also be printed on it, serving a certain identification and promotional purpose. However, due to its simple manufacturing process, it is easily counterfeited and does not provide anti-counterfeiting protection.
[0004] However, the sealing tape for sanitary napkin wraps needs to be able to adhere firmly while allowing the other end to be lifted without tearing the wrap. Therefore, commonly available printed anti-counterfeiting sealing tapes cannot meet the adhesion requirements, and it is also difficult to control the adhesion of anti-counterfeiting printing to meet the adhesive requirements of the tape.
[0005] Therefore, it is necessary to improve the existing sealing and anti-counterfeiting tapes to solve the above problems. Summary of the Invention
[0006] This utility model overcomes the shortcomings of the prior art by providing a sealing anti-counterfeiting tape and a double-layer anti-counterfeiting tape structure, aiming to solve the problem.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sealing anti-counterfeiting tape and a double-layer anti-counterfeiting tape structure, comprising: a substrate, and protective coating and anti-counterfeiting coating units respectively connected to the substrate;
[0008] The protective coating and the anti-counterfeiting coating unit are respectively disposed above and below the substrate. The cross-sectional area of the anti-counterfeiting coating unit is smaller than the cross-sectional area of the substrate. An adhesive layer is disposed below the substrate. The upper surface of the adhesive layer is on the same horizontal plane as the upper surface of the anti-counterfeiting coating unit. The thickness of the adhesive layer is greater than the thickness of the anti-counterfeiting coating unit. The adhesive layer wraps the sides and bottom of the anti-counterfeiting coating unit.
[0009] The anti-counterfeiting coating unit includes: a first anti-counterfeiting coating and a second anti-counterfeiting coating disposed on one side of the first anti-counterfeiting coating. The first anti-counterfeiting coating and the second anti-counterfeiting coating are located on the same horizontal plane, and the top surfaces of the first anti-counterfeiting coating and the second anti-counterfeiting coating are respectively connected to the substrate.
[0010] In a preferred embodiment of this utility model, the connection between the first anti-counterfeiting coating and the second anti-counterfeiting coating and the substrate is one of the following methods: color masterbatch coloring, offset printing, digital printing, relief printing, or gravure printing.
[0011] In a preferred embodiment of this utility model, the first anti-counterfeiting coating is an anti-counterfeiting pattern, and the second anti-counterfeiting coating is one of a QR code, a barcode, and a string of numbers.
[0012] In a preferred embodiment of this utility model, the substrate is a flexible PP substrate film layer, the protective coating is a heat-insulating light-curing coating, and the adhesive layer is a pressure-sensitive adhesive layer.
[0013] In a preferred embodiment of this utility model, the thickness of the substrate is 20μm-200μm, the thickness of the protective coating is 0.5μm-15μm, the thickness of the anti-counterfeiting coating unit is 0.5μm-15μm, and the thickness of the adhesive layer is 8μm-40μm.
[0014] To achieve the above objectives, the second technical solution adopted by this utility model is: a double-layer anti-counterfeiting tape structure.
[0015] In a preferred embodiment of this utility model, the double-layer anti-counterfeiting tape structure includes: an upper sealing anti-counterfeiting tape and a lower sealing anti-counterfeiting tape disposed below the upper sealing anti-counterfeiting tape, wherein both the upper sealing anti-counterfeiting tape and the lower sealing anti-counterfeiting tape are sealing anti-counterfeiting tapes; the width of the upper sealing anti-counterfeiting tape is greater than the width of the lower sealing anti-counterfeiting tape, and the upper sealing anti-counterfeiting tape and the lower sealing anti-counterfeiting tape are aligned in the length direction.
[0016] In a preferred embodiment of this utility model, the substrate, the protective coating, the anti-counterfeiting coating unit, and the adhesive layer of the lower sealing anti-counterfeiting tape have the same width and aligned edges.
[0017] In a preferred embodiment of this utility model, the adhesive layer of the upper sealing anti-counterfeiting tape is a non-full-coverage adhesive layer, and the substrate of the lower sealing anti-counterfeiting tape is aligned with the side edge of the adhesive layer of the upper sealing anti-counterfeiting tape in the width direction.
[0018] In a preferred embodiment of this utility model, the substrate and the protective coating of the upper sealing anti-counterfeiting tape have the same width and are greater than the width of the adhesive layer. The substrate and the protective coating of the upper sealing anti-counterfeiting tape are aligned in the width direction. The two sides of the adhesive layer of the upper sealing anti-counterfeiting tape in the width direction are respectively aligned with the edges of the substrate of the upper sealing anti-counterfeiting tape and the substrate of the lower sealing anti-counterfeiting tape.
[0019] This utility model solves the defects existing in the background technology, and has the following beneficial effects:
[0020] This utility model provides a sealing anti-counterfeiting tape and a double-layer anti-counterfeiting tape structure. Utilizing a substrate, a protective coating, a first anti-counterfeiting coating, a second anti-counterfeiting coating, and an adhesive layer, the first and second anti-counterfeiting coatings are located on the same horizontal plane. This allows for the simultaneous existence of two different anti-counterfeiting methods under the protection of the protective coating. Compared to existing anti-counterfeiting tapes, the adhesive layer provides protection by wrapping the bottom and sides of the first and second anti-counterfeiting coatings, while also ensuring the difficulty of counterfeiting the tape's anti-counterfeiting methods. This provides a stronger anti-counterfeiting effect, improves anti-counterfeiting performance, and solves the shortcomings of insufficient anti-counterfeiting performance in existing anti-counterfeiting tapes.
[0021] In this invention, the first anti-counterfeiting coating is an anti-counterfeiting pattern, and the second anti-counterfeiting coating is one of a QR code, barcode, or number string. Compared with the prior art, by combining a visual anti-counterfeiting pattern with a scannable QR code, barcode, or number string, a dual anti-counterfeiting measure is provided, making the product more difficult to counterfeit.
[0022] In this invention, the substrate, protective coating, anti-counterfeiting coating unit, and adhesive layer of the lower sealing anti-counterfeiting tape have the same width and aligned edges. Compared with existing technologies, the aligned edges make the seal neater, improving its sealing performance and integrity. The neat edges and consistent width make the anti-counterfeiting features more obvious, facilitating identification and verification by consumers or inspectors. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0028] like Figure 1 As shown, a sealing anti-counterfeiting tape and a double-layer anti-counterfeiting tape structure include: a substrate 100, and a protective coating 200 and an anti-counterfeiting coating unit 300 respectively connected to the substrate 100.
[0029] The protective coating 200 and the anti-counterfeiting coating unit 300 are respectively disposed above and below the substrate 100. The cross-sectional area of the anti-counterfeiting coating unit 300 is smaller than that of the substrate 100. An adhesive layer 400 is disposed below the substrate 100. The upper surface of the adhesive layer 400 and the upper surface of the anti-counterfeiting coating unit 300 are located on the same horizontal plane. The thickness of the adhesive layer 400 is greater than that of the anti-counterfeiting coating unit 300. The adhesive layer 400 covers the sides and bottom of the anti-counterfeiting coating unit 300.
[0030] The anti-counterfeiting coating unit 300 includes: a first anti-counterfeiting coating 310 and a second anti-counterfeiting coating 320 disposed on one side of the first anti-counterfeiting coating 310. The first anti-counterfeiting coating 310 and the second anti-counterfeiting coating 320 are located on the same horizontal plane, and the top surfaces of the first anti-counterfeiting coating 310 and the second anti-counterfeiting coating 320 are respectively connected to the substrate 100.
[0031] The connection between the first anti-counterfeiting coating 310 and the second anti-counterfeiting coating 320 and the substrate 100 is achieved through one of the following methods: masterbatch coloring, offset printing, digital printing, letterpress printing, or gravure printing. Specific printing or coloring techniques make the connection between the anti-counterfeiting coating and the substrate more difficult to counterfeit, thus improving the product's anti-counterfeiting capabilities.
[0032] The first anti-counterfeiting coating 310 is an anti-counterfeiting pattern, and the second anti-counterfeiting coating 320 is one of a QR code, barcode, or number string. By combining the visual anti-counterfeiting pattern with a scannable QR code, barcode, or number string, a dual anti-counterfeiting measure is provided, making the product more difficult to counterfeit.
[0033] The substrate 100 is a flexible PP substrate 100 film layer, the protective coating 200 is a heat-insulating UV-curable coating, and the adhesive layer 400 is a pressure-sensitive adhesive layer. The flexibility of the PP substrate film layer makes the tape easy to roll and unroll, facilitating storage and use. The heat-insulating UV-curable coating provides a certain degree of heat insulation, protecting the items under the tape from high temperatures. The UV-curable coating can cure quickly under specific light source irradiation, shortening production time and improving production efficiency.
[0034] The substrate 100 has a thickness of 20μm-200μm, the protective coating 200 has a thickness of 0.5μm-15μm, the anti-counterfeiting coating unit 300 has a thickness of 0.5μm-15μm, and the adhesive layer 400 has a thickness of 8μm-40μm. The thinness of the substrate provides good flexibility, making the tape easy to bend and adhere to surfaces of different shapes. The thinner substrate and protective coating may have better transparency, helping to showcase the design and information on the anti-counterfeiting coating unit. The narrow thickness range of the protective coating 200 and the anti-counterfeiting coating unit 300 helps maintain coating uniformity and avoids performance differences caused by uneven thickness. Example
[0035] like Figure 2 As shown, a double-layer anti-counterfeiting tape structure includes: an upper sealing anti-counterfeiting tape and a lower sealing anti-counterfeiting tape disposed below the upper sealing anti-counterfeiting tape, wherein both the upper sealing anti-counterfeiting tape and the lower sealing anti-counterfeiting tape are sealing anti-counterfeiting tapes.
[0036] The width of the top sealing anti-counterfeiting tape is greater than the width of the bottom sealing anti-counterfeiting tape, and the top and bottom sealing anti-counterfeiting tapes are aligned along their length. The upper sealing tape is longer than the lower sealing tape, providing more comprehensive coverage, reducing air and moisture penetration, and improving the sealing effect.
[0037] The base material 100, protective coating 200, anti-counterfeiting coating unit 300, and adhesive layer 400 of the bottom sealing anti-counterfeiting tape have the same width and aligned edges. Aligned edges make the seal neater, improving its sealing performance and integrity. The neat edges and consistent width make the anti-counterfeiting features more obvious, facilitating identification and verification by consumers or inspectors.
[0038] The adhesive layer 400 of the upper sealing anti-counterfeiting tape is not a full-coverage adhesive layer, and the substrate 100 of the lower sealing anti-counterfeiting tape is aligned with the side edges of the adhesive layer 400 of the upper sealing anti-counterfeiting tape in the width direction. By not using adhesive in areas where it is not needed, residue left when peeling off the tape is reduced, keeping the adhered surface clean.
[0039] The base material 100 and protective coating 200 of the upper sealing anti-counterfeiting tape have the same width and are wider than the adhesive layer 400. The base material 100 and protective coating 200 are aligned in the width direction. The two sides of the adhesive layer 400 in the width direction are aligned with the edges of the base material 100 of both the upper and lower sealing anti-counterfeiting tapes. The fact that the base material and protective coating are wider than the adhesive layer means that the ends of the tape extend beyond the adhesive portion, providing additional protection and sealing, and reducing edge penetration. It will not be scratched or damaged during product use, resulting in more stable and reliable anti-counterfeiting verification performance. Furthermore, when the tape is torn, the entire tape separates from the adhesive layer, effectively preventing the problem of unauthorized re-application of tape after unauthorized unpacking during transportation, thus improving the security of goods transportation.
[0040] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
