Description

Technical Field

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

[0002] Fragile paper labels are widely used for anti-counterfeiting and anti-tampering purposes. With the continuous development and innovation of anti-counterfeiting technologies, the demand for anti-counterfeiting measures is also gradually increasing. Fluorescent fragile paper anti-counterfeiting labels have broad market prospects in fields such as electronics, pharmaceuticals, and luxury goods. Their high anti-counterfeiting properties and ease of identification make them an ideal choice for anti-counterfeiting labels. Fluorescent fragile paper anti-counterfeiting labels, by combining fluorescent materials and fragile paper technology, provide a highly secure, easily identifiable, and environmentally friendly anti-counterfeiting label solution with broad application prospects and market potential. Utility Model Content

[0003] Traditional fragile paper labels primarily rely on the fragility of the material and the printing of anti-counterfeiting information to achieve tamper-proof and anti-counterfeiting purposes. However, this approach suffers from drawbacks such as limited anti-counterfeiting technology, high production costs, and complex manufacturing processes, failing to meet the ever-increasing demands for anti-counterfeiting measures. To address these technical issues, this invention proposes a fluorescent fragile paper anti-counterfeiting label.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] In a first aspect, a fluorescent fragile paper anti-counterfeiting label is provided, comprising a varnish covering layer, an antibacterial coating, a fluorescent ink layer, a fragile material layer, an adhesive layer, and a glassine release paper layer arranged sequentially; wherein the fluorescent ink layer contains fluorescent fibers.

[0006] Furthermore, the thickness of the varnish covering layer is 3-5 μm.

[0007] Preferably, the varnish covering layer can be developed by wiping with alcohol.

[0008] Preferably, the varnish covering layer has an alcohol-based color-developing effect.

[0009] The varnish covering layer is made of polyurethane acrylate (PUA) UV varnish, which has strong adhesion, good chemical resistance (resistant to alcohol, grease, etc.), and strong scratch resistance. It can effectively protect the fluorescent ink layer and has excellent printing effect, which can meet the printing requirements of anti-counterfeiting labels.

[0010] Preferably, the polyurethane acrylate UV varnish also contains Rhodamine B fluorescent dye developer, which can be developed by wiping with alcohol, thus increasing the means of anti-counterfeiting identification.

[0011] Furthermore, the thickness of the antibacterial coating is 3-5 μm.

[0012] Preferably, the antibacterial coating is a water-based coating containing zinc oxide.

[0013] The antibacterial coating has good antibacterial effect and self-cleaning function, and can be applied to medical packaging.

[0014] Furthermore, the thickness of the fluorescent ink layer is 10-15 μm.

[0015] Preferably, the fluorescent ink layer has a fluorescent recognition effect.

[0016] The fluorescent ink layer is made by mixing polyurethane printable ink, micron-sized fluorescent fibers and toluene solvent. It not only has good printing performance, but also has a fluorescent recognition effect due to the addition of fluorescent fibers. The fluorescent fibers are clearly visible under ultraviolet light, which has high recognition and anti-counterfeiting properties.

[0017] Furthermore, the thickness of the fragile material layer is 75-100 μm.

[0018] Furthermore, the fragile material layer is a PP synthetic paper layer.

[0019] Furthermore, the fragile material layer is a short fiber pulp layer, a PE fragile film layer, a PET fragile film layer, or a PVC fragile film layer.

[0020] The fragile material layer can be made of materials with fragile properties, such as short fiber pulp (e.g., cotton pulp), which is fragile and breaks easily when slightly torn; the fragile material layer can also be made of PE fragile film (PE: polyethylene), PET fragile film (PET: polyethylene terephthalate), or PVC fragile film (PVC: polyvinyl chloride).

[0021] Preferably, the fragile material layer is made of PP synthetic fragile paper material.

[0022] The fragile material layer is fragile and cannot be easily peeled off when the label is tightly attached to the object. The material will tear, thus preventing peeling and detachment.

[0023] Furthermore, the thickness of the adhesive layer is 20-25 μm.

[0024] Furthermore, the adhesive layer is an acrylic adhesive layer.

[0025] The adhesive layer has strong bonding strength and excellent temperature resistance, weather resistance and chemical corrosion resistance, which can ensure that the label and the backing material are firmly attached together.

[0026] Furthermore, the basis weight of the glassine release paper layer is 60-90 gsm.

[0027] Furthermore, the glassine release paper layer has multiple grids.

[0028] The glassine release paper layer can form a crisscross grid on the adhesive surface of the adhesive layer, ensuring rapid air release during label application and preventing the formation of air bubbles.

[0029] Secondly, a method for preparing a fluorescent fragile paper anti-counterfeiting label as described in the first aspect is provided, comprising the following steps:

[0030] S1. Apply fluorescent ink to one side of the fragile material layer, and form a fluorescent ink layer after drying;

[0031] S2. Apply an antibacterial coating to the surface of the fluorescent ink layer away from the fragile material layer and allow it to dry;

[0032] S3. Apply a varnish masking layer to the surface of the antibacterial coating away from the fluorescent ink layer and then UV cure it;

[0033] S4. Apply adhesive to the release surface of the glassine release paper layer to form an adhesive layer. After drying in an oven, attach it to the side of the fragile material layer away from the fluorescent ink layer to obtain a fluorescent fragile paper anti-counterfeiting label.

[0034] This utility model provides a fluorescent fragile paper anti-counterfeiting label. Compared with the prior art, the advantages of this fluorescent fragile paper anti-counterfeiting label are: it is fragile and has good antibacterial effect, and it can achieve its high anti-counterfeiting characteristics through fluorescent recognition and alcohol color development, which greatly improves the anti-counterfeiting effect and saves production costs.

[0045] Example

[0046] like Figure 1-2The fluorescent fragile paper anti-counterfeiting label shown includes, in sequence, a varnish covering layer 1, an antibacterial coating layer 2, a fluorescent ink layer 3, a fragile material layer 4, an adhesive layer 5, and a glassine release paper layer 6; the fluorescent ink layer 3 contains fluorescent fibers.

[0047] The thickness of the varnish masking layer 1 is 3-5 μm. In this embodiment, the thickness of the varnish masking layer 1 is 4 μm. The varnish masking layer 1 can be developed by wiping with alcohol, thus achieving an alcohol-based color development effect. The varnish masking layer 1 is made of polyurethane acrylate (PUA) UV varnish, which has strong adhesion, good chemical resistance (resistant to alcohol, grease, etc.), and strong scratch resistance, effectively protecting the fluorescent ink layer 3 while providing excellent printing results, meeting the printing requirements of anti-counterfeiting labels. Rhodamine B fluorescent dye developer is also added to the polyurethane acrylate UV varnish, which can be developed by wiping with alcohol, increasing the anti-counterfeiting identification method. The thickness of the antibacterial coating 2 is 3-5 μm. In this embodiment, the thickness of the antibacterial coating 2 is 4 μm. The antibacterial coating 2 is a water-based coating containing zinc oxide. The antibacterial coating 2 has good antibacterial effect and self-cleaning function.

[0048] The thickness of the fluorescent ink layer 3 is 10-15 μm. In this embodiment, the thickness of the fluorescent ink layer 3 is 13 μm. The fluorescent ink layer 3 has a fluorescent recognition effect. The fluorescent ink layer 3 is formulated by mixing polyurethane printable ink, micron-sized fluorescent fibers, and toluene solvent. It not only has good printability but also possesses a fluorescent recognition effect due to the addition of fluorescent fibers. The fluorescent fibers are clearly visible under ultraviolet light, providing high identification and anti-counterfeiting properties.

[0049] The thickness of the fragile material layer 4 is 75-100 μm. In this embodiment, the thickness of the fragile material layer 4 is 85 μm. The fragile material layer 4 is a PP synthetic paper layer. Specifically, the fragile material layer 4 is made of PP synthetic fragile paper material. The fragile material layer 4 has a fragile characteristic; when the label is tightly adhered to the object, it cannot be easily peeled off and will tear, thus serving the purpose of preventing peeling and tampering.

[0050] The adhesive layer 5 has a thickness of 20-25 μm. In this embodiment, the adhesive layer 5 has a thickness of 20 μm. The adhesive layer 5 is an acrylic adhesive layer. The adhesive layer 5 has strong adhesion and excellent temperature resistance, weather resistance, and chemical corrosion resistance, ensuring a strong bond between the label and the backing material. The glassine release paper layer 6 has a basis weight of 60-90 gsm. In this embodiment, the glassine release paper layer 6 has a basis weight of 75 gsm. The glassine release paper layer 6 has multiple grids. The glassine release paper layer 6 forms a crisscross grid on the adhesive surface of the adhesive layer 5, ensuring rapid air release during label application and preventing the formation of air bubbles.

[0051] The method for preparing the fluorescent fragile paper anti-counterfeiting label includes the following steps:

[0052] S1. Apply fluorescent ink to one side of the fragile material layer 4, and after drying, form a fluorescent ink layer 3;

[0053] S2. Apply an antibacterial coating 2 to the surface of the fluorescent ink layer 3 away from the fragile material layer 4, and then dry it;

[0054] S3. Apply a varnish masking layer 1 to the surface of the antibacterial coating 2 away from the fluorescent ink layer 3, and then perform UV curing;

[0055] S4. Apply adhesive to the release surface of the glassine release paper layer 6 to form an adhesive layer 5. After drying in an oven, adhere it to the side of the fragile material layer 4 away from the fluorescent ink layer 3 to obtain a fluorescent fragile paper anti-counterfeiting label.

[0056] In another embodiment, the fragile material layer also contains fluorescent fibers. The fluorescent fibers are added to the fragile paper material masterbatch, mixed evenly, and then cast and pressed to form a fluorescent fragile material film, which can also achieve the corresponding fluorescent effect. However, this is a customized material with a large minimum order quantity and high production cost.

[0057] In summary, this novel fluorescent fragile paper anti-counterfeiting label, in addition to possessing the fragility of ordinary fragile labels, also features fluorescent identification and alcohol-based color development. The fluorescent pattern is clearly visible under ultraviolet light, and the label develops color upon wiping with alcohol, facilitating identification. Furthermore, it exhibits excellent antibacterial properties, making it suitable for medical packaging. This significantly enhances the anti-counterfeiting effect and reduces the difficulty of counterfeiting, while simultaneously lowering production costs.

[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
