Example 1
Referring to fig. 1, the present embodiment provides a laser holographic anti-counterfeiting film 100A, wherein the laser holographic anti-counterfeiting film 100A includes a protective layer 110, a dielectric layer 120, an information recording layer 130, a first reflective layer 140, a base film layer 150, a second reflective layer 160, and a hot melt adhesive layer 170, which are sequentially connected from outside to inside.
In this embodiment, "inner" means a side to which the laser hologram antifake film 100A can be attached to the surface of the package, and "outer" means a side relatively distant from the attached package.
The hot melt adhesive layer 170 has a certain viscosity, and can be used for printing stock, so that the laser holographic anti-counterfeiting film 100A can be applied to an object. The material for forming the hot melt adhesive layer 170 may be selected from commercially available adhesive materials.
The thickness of the hot melt adhesive layer 170 is 2-5 microns, and specifically may be 2 microns, 3 microns, 4 microns, 5 microns or any value between any 2 point values, such as 2.5 microns, 2.8 microns, 3 microns, 3.2 microns, 4.5 microns, etc. The thickness of the hot melt adhesive layer 170 is 3 μm in this embodiment.
The base film layer 150 functions as the first reflective layer 140 and the second reflective layer 160, so as to ensure the formation of the anti-counterfeiting pattern with dynamic moire effect, and the anti-counterfeiting pattern can be observed by human eyes. The thickness of the base film layer 150 is 12-75 microns, and may be any value between 12-75 microns, such as 12 microns, 50 microns, 30 microns, 25 microns, 75 microns, 60 microns, 70 microns, and 68 microns, for example. And the material forming the base film may be any one of conventional resins in the prior art, for example, thermoplastic resins, such as film materials of PVC, PET, PS, PP, PC, and the like. The material forming the base film layer 150 in this embodiment is PET, and the thickness of the base film layer 150 is 50 micrometers.
The second reflective layer 160 is provided with a second reflective region 161 and a second blank region 162, the first reflective layer 140 is provided with a first reflective region 141 and a first blank region 142, the first reflective region 141 and the second reflective region 161 are arranged in a staggered manner, the first blank region 142 and the second blank region 162 are arranged in a staggered manner, and then after the first reflective layer 140 and the second reflective layer 160 are adhered to the two sides of the base film layer 150, an anti-counterfeiting pattern with a dynamic moire effect is formed under illumination. That is, the first and second reflective layers 140 and 160 are adhered to both sides of the base film layer 150, the first and second reflective layers 140 and 160 are overlapped.
It should be noted that the anti-counterfeit pattern with dynamic moire effect formed under the illumination condition of the present invention means that the anti-counterfeit pattern can be observed under daily illumination without additional special illumination.
The staggered arrangement of the first reflective area 141 and the second reflective area 161 and the staggered arrangement of the first blank area 142 and the second blank area 162 means that the first reflective area 141 and the second reflective area 161 overlap each other but do not completely overlap each other, that is, when the first reflective layer 140 and the second reflective layer 160 overlap each other, the first reflective area 141 and the second reflective area 161 partially overlap each other, the first blank area 142 and the second reflective area 161 partially overlap each other but do not completely overlap each other, and the first blank area 142 and the second blank area 162 are the same.
Meanwhile, the first reflective region 141 and the first blank region 142 are disposed by substantially removing a part of reflective materials on the first reflective layer 140 (for example, hollowing out the first reflective layer 140 to form a hollow, or directly disposing a specific region without filling reflective materials when preparing the first reflective layer 140, and then the unfilled region is a blank region), or coating a part of non-reflective materials on the first reflective layer, and then removing the reflective materials or coating the region without reflective materials is the first blank region 142, and the remaining region on the first reflective layer 140 is the first reflective region 141. However, the reflective material on the first reflective layer 140 is removed or the non-reflective material is disposed on the first reflective layer 140, so that the first blank area 142 and the second blank area 162 can be interlaced, thereby ensuring the formation of the anti-counterfeit pattern with dynamic moire effect.
The second blank area 162 and the second reflective area 161 of the second reflective layer 160 are arranged in the same manner as the first blank area 142 and the first reflective area 141 of the first reflective layer 140, except that the first reflective area 141 and the second reflective area 161 are arranged alternately, and the first blank area 142 and the second blank area 162 are arranged alternately, so that the anti-counterfeiting pattern with dynamic moire effect can be formed after the first reflective layer 140 and the second reflective layer 160 are adhered to both sides of the base film layer 150.
The first reflective region 141 and the first blank region 142 of the first reflective layer 140 and the second reflective region 161 and the second blank region 162 of the second reflective layer 160 can be disposed in various ways, as long as the first reflective region 141 and the second reflective region 161, the first blank region 142, and the second blank region 162 can form an anti-counterfeit pattern with dynamic moire effect after the first reflective layer 140 and the second reflective layer 160 are adhered to both sides of the base film layer 150.
Referring to fig. 2, by way of example in the embodiment, a plurality of first hollow points 1421 are formed on the first reflective layer 140, the plurality of first hollow points 1421 are linearly arranged to form a row of first hollow array points 1422, then a plurality of rows of first hollow array points 1422 are formed on the first reflective layer 140 in the same manner, and each row of first hollow array points 1422 is obliquely arranged along a direction relatively far away from the horizontal plane; the plurality of rows of the first hollow array points 1422 are disposed in parallel, that is, in this embodiment, the plurality of rows of the first hollow array points 1422 are the first blank regions 142, and the region of the first reflective layer 140 except the first hollow array points 1422 is the first reflective region 141.
The horizontal plane relatively distant from or along the horizontal plane described in the embodiments of the present invention is a horizontal plane in which a plane to which the first reflective layer of the laser hologram anti-counterfeiting film belongs is a reference plane.
Referring to fig. 3, a plurality of rows of second hollow-out points 1621 are also formed on the second reflective layer 160, the plurality of second hollow-out points 1621 are also linearly arranged to form a row of second hollow-out points 1622, a plurality of rows of second hollow-out points 1622 are formed on the second reflective layer 160 in the same manner, and the plurality of rows of second hollow-out points 1622 are arranged in an array manner, i.e., the plurality of rows of second hollow-out points 1622 are the second blank area 162 in this embodiment, and the second reflective layer 160 is provided with a second reflective area 161 except the second hollow-out points 1622.
Therefore, when the first reflective layer 140 and the second reflective layer 160 are disposed on two sides of the base film layer 150, the first blank area 142 and the second blank area 162, the first reflective area 141 and the second reflective area 161 are partially overlapped, the first blank area 142 and the second reflective area 161 are also partially overlapped, and the second blank area 162 and the first reflective area 141 are also partially overlapped, so that a moire effect of light and dark intersection can be observed when observing from the outside of the film, and when the observation angle changes, the pattern generates a dynamic effect, which is more beneficial to anti-counterfeiting.
Further, the thicknesses of the first reflective layer 140 and the second reflective layer 160 are 10-40 nm, respectively, and may be any value between 10-40 nm, such as 10 nm, 20 nm, 30 nm, 40 nm, 15 nm, 25 nm, and 35 nm.
