Description

Technical Field

[0001] This utility model belongs to the field of tape technology, specifically relating to a sealing anti-counterfeiting tape with composite anti-counterfeiting features. Background Technology

[0002] Packaging tape, also known as BOPP tape or packaging tape, is made of BOPP film as the base material and is made by heating and evenly coating pressure-sensitive adhesive. It is an indispensable product for enterprise production, sales and personal life.

[0003] Traditional sealing tape only seals boxes and has weak anti-counterfeiting properties, making it easy to counterfeit and easily peeled off by heating. To address this issue, those skilled in the art have developed sealing tapes with anti-counterfeiting and anti-peeling functions. For example, the utility model patent technology entitled "Printed Anti-counterfeiting Tape," authorized and published by the Chinese Patent Office on February 27, 2024, with publication number CN220537730U, has a layer structure comprising, from top to bottom, an isolation layer, a substrate layer, a feature layer, a printing layer, and an adhesive layer. The feature layer is a special release material with partial printing. In this utility model, the anti-counterfeiting information is hidden in the feature layer, which is transparent and colorless. The anti-counterfeiting information cannot be detected before the tape is removed from the object, and the tape cannot be re-attached to the feature layer after removal, thus preventing restoration and achieving the functions of anti-counterfeiting and anti-peeling.

[0004] Although the aforementioned sealing tape has anti-tampering and anti-counterfeiting properties, it still has the shortcomings of having few anti-counterfeiting technologies and weak anti-counterfeiting performance. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing anti-counterfeiting tape with composite anti-counterfeiting features, which applies multiple anti-counterfeiting technologies such as holographic anti-counterfeiting technology, fluorescent anti-counterfeiting technology, and hollow plating anti-counterfeiting technology to the tape to improve its anti-counterfeiting performance.

[0006] This utility model is achieved through the following technical solution: This refers to a type of anti-counterfeiting sealing tape with composite anti-counterfeiting features. The tape is characterized by comprising a BOPP film. One side of the BOPP film has a silicone oil release coating, and the other side, from the inside out, sequentially comprises a perforated release layer, a coding information layer, a fluorescent ink information layer, a perforated aluminum-plated hidden code information layer, a perforated aluminum-plated layer, a molded information layer, a molding coating, and an acrylic pressure-sensitive adhesive layer. The molded information layer includes a holographic information layer and an ink-printed information layer. Specifically, the holographic information layer has a perforated window, and the ink-printed information layer is positioned within the perforated window. The holographic information layer and the perforated aluminum-plated layer are positioned correspondingly, and the perforated aluminum-plated hidden code information layer partially covers the perforated aluminum-plated layer to form a hidden code.

[0007] The BOPP film of this invention undergoes double-sided corona treatment, with corona treatment applied to the front side before coating with a low release force silicone oil, thus maintaining the integrity of the tape's appearance when unwinding.

[0008] The other side of the BOPP film is first coated with a release coating to form a perforation. After peeling off the release layer, corona treatment is applied to ensure that when the tape is peeled off, the other layers can be separated from the BOPP base film, thus achieving the peeling effect.

[0009] The novel invention features a perforated aluminum-plated code information layer covering a perforated aluminum-plated layer. The aluminum layer is thickened at the covered area, and it appears no different from an ordinary aluminum-plated layer. However, under sunlight / light, the information in the perforated aluminum-plated code information layer will be revealed, achieving a good anti-counterfeiting effect.

[0010] The release layer of this invention is not a full-coverage coating, but rather a perforated structure. The release layer can be coated with text, patterns, or other preset anti-counterfeiting information. The release layer is transparent. When the tape is not removed, the tape looks the same as ordinary tape. After the tape is pasted onto the packaging, when it is peeled off again, the release layer and the layers below it are peeled off and left on the packaging surface. The appearance of the tape is destroyed, leaving the shape of the release layer on the box. After the tape is peeled off, the perforated shape of the release layer is revealed and cannot be restored, effectively preventing the tape from being peeled off without damage.

[0011] The inkjet printing information layer of this utility model is one or any combination of barcodes, QR codes, and anti-counterfeiting codes.

[0012] The fluorescent ink information layer of this invention is printed with fluorescent anti-counterfeiting ink, which is invisible under normal conditions and can only be seen when exposed to ultraviolet light.

[0013] The perforated aluminum plating layer of this utility model is obtained by using one of the existing technologies of water-washed aluminum, alkaline-washed aluminum, or vacuum direct plating perforation process.

[0014] The molded information layer of this utility model is made using an existing integrated molding and printing machine. The molding and printing processes are completed online, which enables more accurate registration. Moreover, since integrated molding and printing machines are expensive, small workshops generally cannot afford them, which greatly limits the imitation of the tape.

[0015] Furthermore, a full-coverage base color layer is provided between the molding coating and the acrylic pressure-sensitive adhesive layer of this utility model.

[0016] This utility model features a full-coverage background layer. When peeled off, part of the background layer remains on the tape, while the rest remains on the packaging, creating a more obvious contrast. Furthermore, the background layer allows the tape color to better integrate with the company's product / packaging / characteristics. For example, the base color of Moutai liquor packaging is yellow, and using yellow anti-counterfeiting tape on the packaging further highlights the product's features.

[0017] Furthermore, the coding information layer of this utility model is a color variable coding.

[0018] Color variable inkjet coding is an existing anti-counterfeiting technology. It has been widely used in the packaging materials field, such as CN110718139A, a holographic anti-counterfeiting film with variable color digital codes, CN113326907A, and a method for producing color variable barcodes, which further enhances the anti-counterfeiting performance of tapes.

[0019] The process flow of this utility model can be briefly described as follows: The process involves: applying a cutout release layer to a BOPP film in a localized location → applying a molding coating to a PET transfer film → molding → aluminizing → aluminizing wash → cutout plating → printing fluorescent ink → coding → dry lamination → applying silicone oil → applying adhesive → slitting.

[0020] Compared with existing technologies, the anti-counterfeiting tape for sealing boxes provided by this utility model integrates holographic anti-counterfeiting technology, hollow plating anti-counterfeiting technology, fluorescent anti-counterfeiting technology, and variable inkjet coding anti-counterfeiting technology, resulting in a better anti-counterfeiting effect.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which this invention pertains. Example 1

[0024] like Figure 1As shown: The front of the BOPP film 2 is provided with a silicone oil release coating 1, and the back is provided with a perforated release layer 3, a coding information layer 4, a fluorescent ink information layer 5, a perforated aluminum-plated code information layer 6, a perforated aluminum-plated layer 7, a molded information layer, a molding coating 10, and an acrylic pressure-sensitive adhesive layer 11 from the inside to the outside. The molded information layer includes a holographic information layer 9 and an ink-printed information layer 8, that is, the holographic information layer 9 has a perforated window, and the ink-printed information layer 8 is set in the perforated window. The holographic information layer 9 and the perforated aluminum-plated layer 7 are positioned correspondingly, and the perforated aluminum-plated code information layer 6 partially covers the perforated aluminum-plated layer 7 to form a code.

[0025] The BOPP2 film of this invention undergoes double-sided corona treatment. First, corona treatment is applied to the front side, and then a low release force silicone oil is coated to form a silicone oil release coating 1. When unwinding, the integrity of the tape's appearance is maintained.

[0026] On the other side of the BOPP film 2, a release coating is first applied to form a perforated layer. After peeling off the release layer 3, corona treatment is applied to ensure that when the tape is peeled off, the other layers can be separated from the BOPP base film, thus achieving the peeling effect.

[0027] In this embodiment, the tape has a perforated aluminum-plated layer at 7 locations, and a perforated aluminum-plated code information layer 6 is provided at each of these locations.

[0028] The manufacturing process in this embodiment is as follows: a cutout release layer is applied to a localized area on the BOPP film → a molding coating is applied to the PET transfer film → molding → aluminum plating → aluminum washing → cutout plating → printing fluorescent ink → inkjet coding → dry lamination → applying silicone oil → applying adhesive → slitting. Example 2

[0029] like Figure 2 As shown: A full-coverage base color layer 12 is also provided between the molding coating 10 and the acrylic pressure-sensitive adhesive layer 11, and the rest is the same as in Example 1.

[0030] Compared to Example 1, this embodiment features a full-coverage background layer 12. When peeled off, part of the background layer 12 remains on the tape, while part remains on the packaging. The contrast is more obvious after peeling. Furthermore, the background layer 12 allows the tape color to better integrate with the company's product / packaging / characteristics. For example, the base color of Moutai liquor packaging is yellow, and using yellow anti-counterfeiting tape on the packaging better reflects the product's characteristics.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
