[0002] While existing anti-counterfeiting labels can prevent counterfeit and substandard products to a certain extent, they still have some shortcomings. For example, static holographic images are easily imitated, and a single anti-counterfeiting method is unable to cope with increasingly sophisticated counterfeiting techniques. Therefore, a new type of holographic laser film anti-counterfeiting label is needed that can improve the anti-counterfeiting effect through dynamic holographic images and multiple anti-counterfeiting functions. Utility Model Content

[0003] The purpose of the utility model is to address the problems existing in the background technology and to propose a holographic laser film anti-counterfeiting label.

[0004] The technical solution of the utility model is: a holographic laser film anti-counterfeiting label, which comprises a substrate layer, a first holographic laser layer, a QR code layer, a second holographic laser layer and a printing layer from bottom to top;

[0005] The first holographic laser layer includes a dynamically changing holographic image layer formed on the substrate layer by laser exposure, and also includes a plurality of microstructures formed on the holographic image layer by micro-nano processing, and the plurality of microstructures are combined to form a dynamic anti-counterfeiting feature layer;

[0006] The second holographic laser layer includes an adhesive layer hot-stamped on the two-dimensional code layer, a scratch-off silver layer on the adhesive layer, and a second holographic layer hot-stamped on the scratch-off silver layer.

[0007] Preferably, the first holographic laser layer further comprises an encrypted information layer formed between the substrate layer and the holographic image layer by inkjet printing, wherein the inkjet printing uses fluorescent ink that can be excited by ultraviolet rays.

[0008] Preferably, the image of the holographic image layer includes at least three layers of three-dimensional graphics with different depths.

[0009] Preferably, the dynamic anti-counterfeiting feature layer is formed by laser etching technology with nanometer-level precision to form a plurality of microstructures, and the width of the microstructures is less than nanometers.

[0010] Compared with the existing technology, the beneficial effects of the present invention are: this solution greatly improves the anti-counterfeiting effect by setting the first holographic laser layer and the second holographic laser layer. The first holographic laser layer adopts a dynamic holographic image, and the combination of the dynamic holographic image and the micro-nano structure makes it difficult for counterfeiters to copy, and the encrypted information layer further increases the complexity of anti-counterfeiting. In addition, the setting of the second holographic laser layer makes the anti-counterfeiting label form a double holographic laser layer, further improving the anti-counterfeiting effect. In addition, the second holographic layer is set on the traditional scratch-off silver, which improves the ornamental value of the scratch-off silver layer while making the QR code information at the bottom more clearly visible.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Refer to the attached Figure 1-3 A holographic laser film anti-counterfeiting label, which includes a substrate layer 1, a first holographic laser layer 2, a two-dimensional code layer 3, a second holographic laser layer 4 and a printing layer 5 from bottom to top.

[0017] The first holographic laser layer 2 includes a dynamically changing holographic image layer 21 formed on the substrate layer 1 by laser exposure, and also includes a plurality of microstructures formed on the holographic image layer 21 by micro-nano processing. The plurality of microstructures are combined to form a dynamic anti-counterfeiting feature layer 22.

[0018] In this way, the anti-counterfeiting effect is greatly improved by adopting dynamic holographic images. The combination of dynamic holographic images and micro-nano structures makes it difficult for counterfeiters to copy, and the encrypted information layer further increases the complexity of anti-counterfeiting.

[0019] The second holographic laser layer 4 includes an adhesive layer 41 hot-stamped on the two-dimensional code layer 3 , a scratch-off silver layer 42 on the adhesive layer 41 , and a second holographic layer 43 hot-stamped on the scratch-off silver layer 42 .

[0020] In addition, the second holographic laser layer 4 is provided, so that the anti-counterfeiting label forms a double holographic laser layer, which further improves the anti-counterfeiting effect. In addition, the second holographic layer 43 is provided on the traditional scratch-off silver, which improves the ornamental value of the scratch-off silver layer 42 and makes the QR code information at the bottom more clearly visible.

[0021] In this embodiment, the first holographic laser layer 2 further includes an encrypted information layer 23 formed between the substrate layer 1 and the holographic image layer 21 by inkjet printing, wherein the inkjet printing uses fluorescent ink that can be excited by ultraviolet rays.

[0022] The encrypted information layer 23 is formed with encrypted information invisible to the naked eye through inkjet printing technology. Moreover, the encrypted information is visible only under ultraviolet light of a specific wavelength and contains a unique serial number and a check code.

[0023] The image of the holographic image layer 21 includes at least three layers of three-dimensional graphics with different depths. The image can present different visual effects at different angles and has the function of dynamic transformation.

[0024] In addition, the dynamic anti-counterfeiting feature layer 22 uses nanometer-level precision laser etching technology to form a number of microstructures. The width of the microstructures is less than 100 nanometers, which ensures the fineness and complexity of the pattern. These microstructures can display dynamically changing patterns or texts under specific angles and light sources.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
