Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting label technology, and in particular to a nuclear microporous anti-counterfeiting label. Background Technology

[0002] Existing technology, such as Chinese utility model patent document, publication number CN215834137U, discloses a nuclear microporous anti-counterfeiting label, which is provided with a nuclear microporous layer, an information anti-counterfeiting layer and an anti-transfer layer from top to bottom. The nuclear microporous layer is used to apply and play an anti-counterfeiting role. The information anti-counterfeiting layer has at least one layer and is used to record relevant information. The anti-transfer layer is used to adhere to the product and can prevent the label from being transferred as a whole.

[0003] Based on the above, in existing technologies, the nuclear microporous layer is simply applied, and authenticity is determined by whether the applied liquid penetrates it. This type of nuclear microporous layer has limited functionality and provides only a low level of anti-counterfeiting effect. Furthermore, the nuclear microporous layer cannot be combined with other information layers for integrated anti-counterfeiting measures, and further improvements are needed. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a nuclear microporous anti-counterfeiting label.

[0005] A nuclear microporous anti-counterfeiting label designed for this purpose includes, from bottom to top, an adhesive layer, an information anti-counterfeiting layer, a water-sensitive transparent layer, and a nuclear microporous membrane.

[0006] The water-sensitive transparent layer is used to block the information of the anti-counterfeiting layer.

[0007] The nuclear microporous membrane allows liquid to permeate into the water-sensitive transparent layer.

[0008] Preferably, the information anti-counterfeiting layer includes at least a hidden information layer disposed between the adhesive layer and the water-sensitive transparent layer.

[0009] Preferably, the information anti-counterfeiting layer includes at least an anti-transfer layer disposed between the adhesive layer and the water-sensitive transparent layer.

[0010] Preferably, the information anti-counterfeiting layer includes a hidden information layer and an anti-transfer layer;

[0011] The hidden information layer and the anti-transfer layer are spaced apart vertically.

[0012] Preferably, the anti-transfer layer is disposed above the hidden information layer.

[0013] Preferably, the anti-transfer layer is fragile paper.

[0014] Preferably, the water-transparent layer is an ink layer printed with water-transparent ink.

[0015] Compared with existing technologies, this invention comprises, from bottom to top, an adhesive layer, an anti-counterfeiting layer, a water-sensitive transparent layer, and a nuclear microporous membrane. The water-sensitive transparent layer is used to block the information of the anti-counterfeiting layer; the nuclear microporous membrane allows liquid to permeate to the water-sensitive transparent layer. This invention uses a nuclear microporous membrane in conjunction with the water-sensitive transparent layer. Under normal conditions, the water-sensitive transparent layer is opaque, blocking the information of the anti-counterfeiting layer below, making the information of the anti-counterfeiting layer invisible. When a user purchases a product, liquid can permeate downwards to the water-sensitive transparent layer, which becomes transparent upon contact with water, allowing the user to see the information of the anti-counterfeiting layer through the nuclear microporous membrane and the water-sensitive transparent layer, thus achieving an anti-counterfeiting function.

[0025] See Figure 1 A nuclear microporous anti-counterfeiting label comprises, from bottom to top, an adhesive layer 10, an information anti-counterfeiting layer 20, a water-reactive transparent layer 30, and a nuclear microporous membrane 40. The water-reactive transparent layer 30 is used to block the information of the information anti-counterfeiting layer 20; the nuclear microporous membrane 40 allows liquid to permeate to the water-reactive transparent layer 30. This invention uses a nuclear microporous membrane in conjunction with the water-reactive transparent layer. Under normal conditions, the water-reactive transparent layer is opaque, blocking the information of the underlying information anti-counterfeiting layer, making the information of the information anti-counterfeiting layer invisible. When a user purchases a product, liquid can permeate downwards to the water-reactive transparent layer, which becomes transparent upon contact with water, allowing the user to see the information of the information anti-counterfeiting layer through the nuclear microporous membrane and the water-reactive transparent layer, thus achieving an anti-counterfeiting function.

[0026] Furthermore, the water-transparent layer 30 is an ink layer printed with water-transparent ink, which is a commercially available product.

[0027] See Figure 1 The information anti-counterfeiting layer 20 includes at least a hidden information layer 210 disposed between the adhesive layer 10 and the water-sensitive transparent layer 30. The hidden information layer 210 is a printed layer, and its upper surface is printed with anti-counterfeiting information / product information / promotional information.

[0028] See Figure 1 The information anti-counterfeiting layer 20 includes at least an anti-transfer layer 220 disposed between the adhesive layer 10 and the water-sensitive transparent layer 30.

[0029] The anti-transfer layer 220 can be printed with anti-counterfeiting information or patterns according to anti-counterfeiting requirements.

[0030] The anti-transfer layer 220 is made of fragile paper.

[0031] See Figure 1 The information anti-counterfeiting layer 20 includes a hidden information layer 210 and an anti-transfer layer 220; the hidden information layer 210 and the anti-transfer layer 220 are arranged vertically with a gap between them. When the hidden information layer 210 and the anti-transfer layer 220 are arranged vertically with an overlap, the anti-transfer layer 220 plays a role in preventing transfer, while the hidden information layer 210 plays a role in recording anti-counterfeiting information.

[0032] See Figure 1 The anti-transfer layer 220 is disposed above the hidden information layer 210. In this embodiment, the substrate of the anti-transfer layer 220 is a transparent substrate, allowing the user to observe the information located in the hidden information layer 210 through the anti-transfer layer 220.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
