Description

Technical Field

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

[0002] Adhesive tape is a commonly used auxiliary packaging material. Patent publication document CN206143114U discloses an anti-counterfeiting tape. This tape has four layers: a release film layer (reference numeral 1 in the document), a thermal adhesive layer (reference numeral 2 in the document), a pressure-sensitive adhesive layer (reference numeral 3 in the document), and a substrate layer (reference numeral 4 in the document). Anti-counterfeiting is achieved by printing information on the thermal adhesive layer. Because the release film layer, thermal adhesive layer, pressure-sensitive adhesive layer, and substrate are all planarly composited, the ends of the thermal adhesive layer are exposed after the tape is cut. This exposure allows some thermal adhesive to spill into the environment, damaging the thermal adhesive layer and thus losing its anti-counterfeiting effect. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes an anti-counterfeiting tape with a thermal coating disposed within a protective cavity. When cutting this type of anti-counterfeiting tape, as long as the cutting point is not located within the protective cavity, the protective cavity will not be damaged, and the thermally sensitive material on the thermal coating will not spill into the environment, thus ensuring the integrity of the thermal coating.

[0004] The technical solution adopted by this utility model is as follows:

[0005] An anti-counterfeiting tape includes a substrate layer, an adhesive layer, a protective coating, and an anti-adhesive layer. The adhesive layer and the anti-adhesive layer are respectively disposed on both sides of the substrate layer. The protective coating is disposed between the substrate layer and the anti-adhesive layer. Several independent and non-communicating protective cavities are formed between the protective coating and the substrate layer. Each protective cavity is coated with a heat-sensitive coating.

[0006] In this type of anti-counterfeiting tape, the main structure of the tape is formed by combining a substrate layer, an adhesive layer, a protective coating, and an anti-stick layer. An independent protective cavity is formed between the protective layer and the substrate layer. The thermal coating is set in the protective cavity. When this type of anti-counterfeiting tape is cut during use, as long as the cutting point is not located at the thermal coating, the protective cavity will not be damaged. This will prevent the thermal material on the thermal coating from spilling into the environment and ensure the integrity of the thermal coating.

[0007] In this type of anti-counterfeiting tape, the adhesive layer serves to give the entire tape its stickiness, ensuring that the tape can adhere to the areas that need to be bonded.

[0008] Specifically, in this type of tape, the protective coating is used to protect the heat-sensitive coating from external influences. It has strong wear resistance and waterproof capabilities, and can block some heat, reduce the temperature sensitivity of the heat-sensitive coating, and increase the starting temperature of the heat-sensitive coating's color change.

[0009] Optionally, it also includes through holes, there are multiple through holes, the through holes penetrate the substrate layer, adhesive layer, protective coating and anti-stick layer, there are multiple through holes, two adjacent through holes do not contact each other, the through holes are arranged to form several easy-tear break lines, and a protective cavity is provided between two adjacent easy-tear break lines.

[0010] Through holes are created, penetrating the substrate layer, adhesive layer, protective coating, and release layer. These through holes are arranged to form several easy-tear lines. Therefore, the presence of these through holes facilitates tearing the entire roll of tape into several independent small segments. The tearing process occurs along these easy-tear lines, and because the protective cavity is located between adjacent easy-tear lines, the protective cavity is not damaged during the tearing process, thus preventing damage to the heat-sensitive coating. Specifically, the through holes can be created by needle puncture.

[0011] Optionally, the tear lines are parallel and do not contact each other, and the distance between two adjacent tear lines is equal.

[0012] The tear lines are parallel and do not touch, and the distance between two adjacent tear lines is equal. This ensures that each piece of tape torn off is the same size.

[0013] The beneficial effects of this utility model are: the thermal coating is set inside the protective cavity, and when this type of anti-counterfeiting independent tape is cut during use, as long as the cutting point is not located at the protective cavity, the protective cavity will not be damaged, and the thermal material on the thermal coating will not spill into the environment, thus ensuring the integrity of the thermal coating.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0021] As attached Figure 1 and appendix Figure 2 As shown, an anti-counterfeiting tape includes a substrate layer 104, an adhesive layer 105, a protective coating 102, and an anti-adhesive layer 101. The adhesive layer 105 and the anti-adhesive layer 101 are respectively disposed on both sides of the substrate layer 104. The protective coating 102 is disposed between the substrate layer 104 and the anti-adhesive layer 101. Several independent and non-communicating protective cavities are formed between the protective coating 102 and the substrate layer 104. Each protective cavity is coated with a heat-sensitive coating.

[0022] In this type of anti-counterfeiting tape, the main structure of the tape is formed by combining a substrate layer 104, an adhesive layer 105, a protective coating 102, and an anti-stick layer 101. An independent protective cavity is formed between the protective layer and the substrate layer 104. The thermal coating 103 is disposed in the protective cavity. When this type of anti-counterfeiting tape is cut during use, as long as the cutting point is not located at the protective cavity, the protective cavity will not be damaged. This will prevent the thermal material on the thermal coating 103 from spilling into the environment, ensuring the integrity of the thermal coating 103. At the same time, it can prevent the thermal coating 103 from being exposed to air and causing discoloration due to heat.

[0023] In this type of anti-counterfeiting tape, the adhesive layer 105 serves to impart adhesiveness to the entire tape, ensuring that the tape can adhere to the areas where it needs to be bonded.

[0024] Specifically, in this type of tape, the protective coating 102 is used to protect the heat-sensitive coating 103 from external influences. It has strong wear resistance and waterproof capabilities, and can block some heat, reduce the temperature sensitivity of the heat-sensitive coating 103, and increase the starting temperature of the heat-sensitive coating 103 discoloration.

[0025] Specifically, in this type of tape, the anti-adhesive layer 101 uses a silicone-free adhesive release agent, YF-668, manufactured by Yefang Company. The thermosensitive coating 103 uses a water-based thermosensitive coating liquid, TYTULIAO02, manufactured by Tianyuan Company (the thermosensitive coating formed by this coating liquid is an irreversible thermosensitive coating). The protective coating 102 uses a water-based acrylic resin coating liquid, BARIASTAR B2000, manufactured by Mitsui Chemicals.

[0026] The substrate can be a plastic film such as PE film.

[0027] In the preparation of this type of tape, a heat-sensitive coating is first applied to the substrate, which is distributed in a discontinuous sheet-like manner. Then, a protective coating is applied to the substrate to cover the heat-sensitive coating. Next, a silicone-free adhesive release agent is applied to the protective coating, and finally, an adhesive is applied to the substrate.

[0028] As attached Figure 1 and appendix Figure 2 As shown, it also includes through holes 106. There are multiple through holes 106. The through holes 106 penetrate the substrate layer 104, the adhesive layer 105, the protective coating 102 and the anti-stick layer 101. There are multiple through holes 106. There is no contact between two adjacent through holes 106. The through holes 106 are arranged to form several easy-tear fracture lines. A protective cavity is provided between two adjacent easy-tear fracture lines.

[0029] Through holes 106 are formed, penetrating the substrate layer 104, adhesive layer 105, protective coating 102, and anti-stick layer 101. The through holes 106 are arranged to form several easy-tear lines. Therefore, the presence of the through holes 106 facilitates tearing the entire roll of tape into several independent small segments. The tearing process occurs along the easy-tear lines, and since the protective cavity is located between adjacent easy-tear lines, the protective cavity will not be damaged during the tearing process, and the heat-sensitive coating 103 will not be damaged. Specifically, the through holes 106 can be formed by needle puncture.

[0030] As attached Figure 1 and appendix Figure 2 As shown, the easy-tear break lines are parallel and do not touch, and the distance between two adjacent easy-tear break lines is equal.

[0031] The tear lines are parallel and do not touch, and the distance between two adjacent tear lines is equal. This ensures that each piece of tape torn off is the same size.

[0032] The above-described embodiments only illustrate some aspects of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
