[0043] In order to overcome the defects of the prior art, the present application provides a sheet composite structure with local positioning laser effect, which can form effective linkage visual effect between patterns, thereby enhancing local light effect and visual effect and supporting customer ordering laser and printing graphics, while the structure is simple and stable, and can meet the requirements of sheet packaging design freedom, visual effect presentation, anti-fake performance, durability and material cost. It should be noted that the sheet composite structure of the present application is applied to a sheet on a plane or a curved surface or an irregular material surface, and the sheet is not limited to a sheet, but can also be part of a three-dimensional structure of an article.

[0044] The specific embodiments and drawings of the present application will be described below. Figure 1 -Appendix Figure 2 The present application is further described and explained.

[0045] The technical scheme of the present application discloses a sheet composite structure with local positioning laser effect, comprising the following structure layers:

[0046] The base film layer 1 is made of PVC, PET or environment-friendly degradable material, and meets the strength and environmental protection requirements; the positioning laser layer 2 comprises at least one local laser area at a preset position, compared with a full-surface laser layer, the utility model only sets the laser area at the preset position, accurately positions the plate laser effect, reduces the consumption of laser material, simultaneously enhances the visual effect and the anti-fake performance, and supports the use of custom patterns in the local part; the reflection layer 3 is arranged on the side, away from the base film layer 1, of the positioning laser layer 2, and improves the brightness of the laser area; the sleeve printing layer 4 is arranged on the outer side of the laser-aluminum-plated layer stack formed by the base film layer 1, the positioning laser layer 2 and the reflection layer 3, the sleeve printing layer 4 comprises graphics or color blocks corresponding to the position of the local laser area, the sleeve printing layer 4 corresponds to the position of the laser area and forms a linked visual effect, and the above structural layers are combined on the surface of the sheet 5 and are bonded with the sheet 5 through the adhesive layer 6. The multi-layer composite structure combines the local positioning laser light effect, reflection enhancement and sleeve printing design, is beneficial to enhancing the optical effect and anti-fake performance of the product, simultaneously simplifies the process steps and saves the material cost.

[0047] In one embodiment, referring to Figure 1 , the sheet composite structure is sequentially provided with the sheet 5, the adhesive layer 6, the reflection layer 3, the positioning laser layer 2, the base film layer 1 and the sleeve printing layer 4 from inside to outside, so as to reasonably arrange the sheet structure and optimize the optical presentation effect. Figure 2 In another embodiment, referring to Figure 2 , the sheet composite structure is sequentially provided with the sheet 5, the adhesive layer 6, the base film layer 1, the positioning laser layer 2, the reflection layer 3 and the sleeve printing layer 4 from inside to outside. In other embodiments, the skilled in the art can use the hierarchical structure with different orders according to the needs.

[0048] In order to ensure that the laser film can be accurately aligned and cut in subsequent processing (such as slitting, die cutting, printing and the like) in the laser film roll production process, the utility model adopts a roll film positioning cutting line process, through the cooperation of the cutting line with the cross rule line, the stepped arrow mark and the like positioning mark, the cutting equipment can accurately cut the roll film into the required width and length, and combine the sheet with the corresponding size to form the required sheet composite structure with the laser effect.

[0049] In one embodiment, the sheet composite structure further comprises a photocuring protective layer 7 arranged between the positioning laser layer 2 and the reflection layer 3, the scratch resistance and weather resistance are improved, the service life is prolonged, and the laser layer is prevented from being oxidized.

[0050] Optionally, the local laser field can be at least one of the following: relief, mirror, frosted, cat's eye, dynamic light-changing effect, or 3D stereoscopic image. In the laser field, dynamic light-changing effect refers to using special optical structures or materials to make the laser pattern or surface exhibit dynamic changes in color or pattern as the viewing angle changes. This effect is usually achieved using the principles of light interference, diffraction, or reflection. When an observer views the laser pattern from different angles, the color, brightness, or the pattern itself will change significantly, used for anti-counterfeiting and decoration. For example: using micro-nano structures (such as gratings) to diffract and interfere with light, making the light appear different colors at different angles; using the interference effect of light in media with different refractive indices through the superposition of multiple thin films to achieve color changes; using the diffraction characteristics of holograms to make the pattern present different visual effects at different angles; and using nanoscale micro-nano structure design to achieve strong interference and scattering of light, thereby producing dynamic color changes, etc. All of the above belong to dynamic light-changing effects and achievable visual effects. In one embodiment, the local laser field of the positioning laser layer 2 employs dynamic light-changing effects and embossing effects. The dynamic light-changing effect can be a cat's eye, a light column, etc., and the embossing can be crystal embossing, platinum embossing, etc. In another embodiment, the local laser field of the positioning laser layer 2 employs a cat's eye effect, a dynamic light-changing effect, and an embossing effect. In yet another embodiment, the local laser field of the positioning laser layer 2 employs one of the following: a mirror effect, an embossing effect, a frosted finish, a cat's eye effect, a dynamic light-changing effect, or a 3D stereoscopic image. In yet another embodiment, the local laser field of the positioning laser layer 2 combines embossing with registered patterns / text / color blocks. Through the laser patterns and optical structures, as the viewing angle changes, dynamic, continuous, and interconnected visual changes occur between different parts of the laser patterns or between the laser patterns and registered printed text / color blocks, thus forming a linked visual effect. This light effect is difficult to replicate, enhancing the anti-counterfeiting level.

[0051] To match the lighting effects required for different scenarios, local laser domains can be set relatively independently in the positioning laser layer 2, or at least partial areas of two local laser domains can be overlapped in the positioning laser layer 2. For example, in one embodiment, one or more effects such as embossing, mirror, frosted, cat's eye, dynamic light-changing effects, or 3D stereoscopic images can be layered.

[0052] In one embodiment, the reflective layer 3 is an aluminum layer or a zinc oxide layer, and there is no release layer between the base film layer 1 and the positioning laser layer 2 for peeling off the base film layer, which reduces production steps and costs and enhances structural strength.

[0053] In one embodiment, at least one local laser field is embedded with anti-counterfeiting micro-images. The line width of the anti-counterfeiting micro-images is 10μm-150μm. The micro-images require a high-magnification magnifying glass or special equipment to identify and are difficult to counterfeit. At the same time, the images are embedded inside the laser field, which does not affect the overall aesthetics. It also provides dual anti-counterfeiting verification points, further improving the anti-counterfeiting level of the product.

[0054] In one embodiment, the sheet composite structure further includes an optical marking portion for registration printing, the optical marking portion comprising:

[0055] The first positioning mark point is set on the edge of the registration printing layer 4;

[0056] The second positioning marker point is set at the edge of the local laser field;

[0057] The first positioning mark point and the second positioning mark point are set to overlap to ensure that the printed text and the laser field are perfectly matched.

[0058] In one embodiment, the proportion of the local laser domain to the surface area of ​​the positioning laser layer 2 can be selected within the range of 5%-80% to balance the cost of laser materials and optical rendering effect, reducing costs while ensuring visual effect. In another embodiment, depending on customer requirements, the proportion of the local laser domain can also be less than 5% or more than 80%.

[0059] In one embodiment, the sheet material is selected from plastic, wood, or metal, and is suitable for making bank cards, membership cards, gift cards, art collection cards, etc.

[0060] This utility model also discloses a card that uses a sheet composite structure with a localized laser effect, which supports custom laser patterns, printed graphics, anti-counterfeiting micro graphics, etc., and has both aesthetic design and anti-counterfeiting performance.

[0061] The foregoing has provided a detailed description of a sheet composite structure with localized laser positioning effect and a card using the sheet composite structure. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea and method of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
