[0002] The sealing label on the package is an important tool for identifying and verifying the integrity of the product package. Such labels usually contain product names, brand logos, etc. Some sealing labels contain anti-counterfeiting marks, such as unique patterns, watermarks or other security features. These marks can help consumers identify genuine products and prevent the circulation of counterfeit and shoddy products. Some sealing labels also adopt personalized design elements, such as unique color combinations, pattern designs, etc.

[0003] The types of anti-counterfeiting patterns of existing sealing labels are diverse, such as holographic patterns, watermarks, three-dimensional images, etc. Holographic patterns produce three-dimensional images through optical effects. Watermarks are semi-transparent visible patterns or texts formed on paper or other media. Three-dimensional images are raised patterns formed on flat materials through special printing techniques, increasing the tactile and visual effects. These types each have different anti-counterfeiting performances and achieve the effects of preventing forgery and replication. However, these patterns do not have a real three-dimensional dynamic effect, have poor anti-counterfeiting performance, and are not conducive to wide application. Summary of the Utility Model

[0029] Please refer to Figures 1 to 3 , the label 100 of one embodiment has a visual curved surface area 101 for presenting a visual curved surface rolling effect. Among them, the curved surface rolling effect means that when the human eye observes the label 100 at different angles, the curved surface presented on the label 100 presents a curved surface rolling effect as the observation angle changes.

[0030] Further, the label 100 includes a first microstructure layer 110, a substrate layer 120, and a second microstructure layer 130 that are sequentially stacked. The first microstructure layer 110 includes a first microlens array 111 located in the visual curved surface area, and the second microstructure layer 130 includes a first micrographic array 131 corresponding to the first microlens array 111. Among them, the first microstructure layer 110 and the second microstructure layer 130 are formed by coating a UV glue on the substrate layer 120, performing die stamping, and then curing by ultraviolet light irradiation.

[0031] Further, the arrangement period of the first micrographic array 131 gradually increases from the center to the periphery of the visual curved surface, and the arrangement period of the first micrographic array 131 at the center position of the visual curved surface is greater than the arrangement period of the corresponding first microlens array 111. Among them, the visual curved surface refers to the visual effect presented in the visual curved surface area 101 when observing the label 100.

[0032] The label of this embodiment is used for packaging sealing, can present a curved surface rolling visual effect, thus has a three-dimensional sense and a sense of movement, thereby enhancing the anti-counterfeiting performance of the product. In addition, it can also enhance the brand image and attract the attention of consumers, which is conducive to wide application.

[0033] On the basis of the foregoing embodiment, the period P of each micrographic in the first micrographic array 131 is obtained based on the following formula:

[0034] P = P1 + δ * sinα;

[0035] Where δ = P2 - P1, P1 is the central period of the visual curved surface, P2 is the peripheral period of the visual curved surface, and α is the angle between the tangent of the visual curved surface corresponding to the micrographic and the surface of the substrate layer 120, as Figure 3 shown.

[0036] The above formula is used to determine the arrangement mode of the micrographics in the first micrographic array 131. It should be noted that the size and curvature of the visual curved surface need to be determined first. It can be understood that under the same size, the smaller the curvature, the more bulging the curved surface effect. As Figure 4 shown, the sizes of curved surface a, curved surface b, and curved surface c are the same, where the curvature of curved surface a is the smallest, the curvature of curved surface b is the second, and the curvature of curved surface c is the largest.

[0037] Specifically in this embodiment, according to the Moiré imaging rule, the central period P1 = 30.1785μm and the peripheral period P2 = 30.855μm are determined, and the period difference δ = P2 - P1 = 0.6765μm is obtained; with the center of the circle as the center, the period P at each position changes according to the angle α between the tangent of the corresponding point on the curved surface and the surface of the substrate layer 120, presenting the curved surface rolling visual effect graphic "M6", as Figure 2 shown.

[0038] On the basis of the foregoing embodiments, the label 100 further includes a non-visual curved surface area 102 on one side of the visual curved surface area 101. The first micro-structure layer 110 further includes a second microlens array located in the non-visual curved surface area 102, and the second micro-structure layer 130 further includes a second micro-graphic array disposed corresponding to the second microlens array.

[0039] On the basis of the foregoing embodiments, the arrangement periods of the first microlens array 111, the second microlens array, and the second micro-graphic array are each fixed. Further, the arrangement periods of the first microlens array 111 and the second microlens array may be the same or different. Specifically, Figure 2 in the label 100 of the illustrated embodiment, the period of the first microlens array 111 is 30 μm, and the period of the second microlens array is 50 μm, which is smaller than the period of the second microlens array, presenting a sunken array graphic "M6", as Figure 2 shown. This is beneficial to increasing the threshold of being replicated and further enhancing the anti-counterfeiting effect. It can be understood that the first micro-structure layer 110 may further include two or more groups of microlens arrays with different periods.

[0040] On the basis of the foregoing embodiments, the curved surface is spherical, ellipsoidal or water-drop shaped. Of course, the curved surface is not limited thereto, and may also be other regular curved surfaces or irregular curved surfaces.

[0041] On the basis of the foregoing embodiments, the first micro-structure layer 110 further includes a relief micro-structure or a light and shadow micro-structure. Specifically, Figure 2 in the label 100 of the illustrated embodiment, the first micro-structure layer 110 further includes a relief micro-structure 112, and the part of "dream" as shown presents a relief effect. It can be understood that the first micro-structure layer in the label of the present invention may further include a light and shadow micro-structure for presenting a light and shadow effect; or other micro-structures for presenting other effects.

[0042] On the basis of the foregoing embodiments, the second micro-structure layer 130 further includes a relief micro-structure 131 or a light and shadow micro-structure, as Figure 6 shown. It can be understood that the second micro-structure layer in the label of the present invention may further include a light and shadow micro-structure for presenting a light and shadow effect; or other micro-structures for presenting other effects.

[0043] On the basis of the foregoing embodiments, the label 100 further includes an adhesive layer 140, and the adhesive layer 140 is located on the side of the second micro-structure layer 130 away from the substrate layer 120. The adhesive layer 140 is used to attach the label 100 to the packaging product.

[0044] On the basis of the foregoing embodiments, the label 100 further includes a first printing layer 150, and the first printing layer 150 is located between the second microstructure layer 130 and the adhesive layer 140.

[0045] On the basis of the foregoing embodiments, the label 100 further includes a second printing layer 160, and the second printing layer 160 is located on the side of the first microstructure layer 110 away from the substrate layer 120. It can be understood that the final product may include both the first printing layer 150 and the second printing layer 160.

[0046] The label of the technical solution of the present utility model is used for packaging sealing, and can present a curved surface rolling visual effect, thus having a three-dimensional sense and a dynamic sense, thereby enhancing the anti-counterfeiting performance of the product. In addition, it can also enhance the brand image and attract the attention of consumers, which is conducive to wide application.
