[0002] In today's printing and packaging field, laser holographic anti-counterfeiting technology has become the "safety guard" of cigarette packets, wine boxes, cosmetic packaging and toothpaste boxes and other products, and its figure can be seen everywhere. The conventional production path of such products is to first fuse the positioning laser holographic film and the cardboard to form a composite material, then cut it into a single sheet according to accurate positioning, and finally give it a beautiful printing effect with a offset press.
[0003] Focusing on beer labels, the laser holographic effect at the present stage mainly concentrates on full-plate plain rainbow holographic, full-plate light column holographic or random distribution of laser presentation. Unfortunately, only the scheme that can display laser effect in a local specific area of the label has not been explored.
[0004] Looking back at those labels that can accurately display laser effect in a local specific area, the existing full-plate plain rainbow holographic, full-plate light column holographic or random distribution of laser holographic effect labels seem to be somewhat inadequate. Their full-plate or random distribution of laser effect, like a flat narrative that cannot highlight the key points, makes the really key information on the label submerged in a "laser ocean", making it difficult to stand out and catch people's eyes.

[0029] DETAILED DESCRIPTION
[0030] The utility model will be explained in detail below in combination with specific embodiments. The following embodiments will help the person skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for the person skilled in the art, on the premise of not departing from the utility model concept, a number of changes and improvements can be made. These all belong to the protection scope of the utility model.
[0031] The utility model provides a paper with laser effect, include: from top to bottom layer arrangement transfer layer 1, laser holographic layer 2, reflective layer 3, composite glue layer 4, graphic layer 5 and paper base material 6, reflective layer 3 includes transparent reflective layer, laser holographic layer includes holographic layer main part and set up in holographic layer main part, with laser effect anti -fake structure, anti -fake structure non -randomly set up in one local area or multiple local areas in holographic layer main part, the position of information content on graphic layer 2 and the position of matching with laser effect anti -fake structure.
[0032] Laser holographic layer 2 is specific laser holographic layer, and the anti -fake structure is only in one or more local areas of holographic layer main part, and the anti -fake structure has laser effect. The anti -fake structure in the specific laser holographic layer includes one or more ways of cat eye, relief, dynamic graphic, 3D stereoscopic image, microtext and / or pattern.
[0033] Graphic layer 5 is a printed graphic layer. As shown in Figure 1 The position of information content (which can be referred to as positioning printed pattern 7) on graphic layer 5 matches the position of anti -fake structure (which can be referred to as positioning optical pattern 8). That is, the specific laser holographic effect of cat eye, relief, etc. in the anti -fake structure coincides with the corresponding graphic position according to the design effect, which can make the information content on graphic layer 5 more obvious under the contrast of the laser effect of the anti -fake structure, so that the information content is more easily perceived by the user, that is, it plays a role in highlighting key information.
[0034] The transfer layer 1 comprises a polyurethane coating, an acrylic coating or a transfer type laser coating. The reflective layer 3 is a zinc sulfide layer, a silicon dioxide layer or a titanium dioxide layer. The composite adhesive layer 4 comprises a solvent type composite adhesive layer or a water-based composite adhesive layer, such as a dry composite adhesive layer, a wet composite adhesive layer, a hot melt adhesive layer, a general film adhesive layer and the like, preferably, the composite adhesive layer 4 comprises a solvent type dry composite adhesive layer or a water-based dry composite adhesive layer. The paper base material comprises a paper base material of 60-90 g / m2, and the paper base material 6 comprises wet strength paper, copper plate paper, aluminum plated paper or laser paper.
[0035] Notably, the existing beer label laser holographic effect cannot set the laser effect scheme such as cat eye, relief, dynamic graphics, 3D stereoscopic image, micro-text in the specified local area. The reason is that the beer label generally adopts 60-90 g / m2 paper, which is relatively thin. When adding specific laser effects in any or specified area by using similar cigarette packets, wine boxes, cosmetics, toothpaste box scheme, the longitudinal and transverse size changes are large and unstable in the positioning holographic paper making process, resulting in poor overprint precision of the offset printing process, low yield and inability to mass production. However, the structure of the present application adopts intaglio or flexographic printing method to print graphics on the paper base material 6, and then the printed paper base material 6 is positioned, pasted and compounded with the layered structure with laser holographic layer. Therefore, even if the paper base material adopts 60-90 g / m2 paper base material, such as the 60-90 g / m2 wet strength paper or copper plate paper, the present application has the advantages of high precision, high yield and mass production.
[0036] In addition, since the structure of the present application is more difficult to achieve local holographic effect than the existing full-plate plain rainbow holographic, full-plate light column holographic or randomly distributed laser holographic effect beer label, it is more popular, and therefore the present application also has better anti-counterfeiting effect.
[0037] More importantly, the present application sets the reflective layer 3 above the graphics layer 5, in order to avoid the shielding of the reflective layer 3 to the content of the graphics layer 5, the reflective layer 3 needs to use a transparent reflective layer, i.e. the general aluminum reflective layer cannot be used, and a transparent reflective layer such as zinc sulfide layer, silicon dioxide layer or titanium dioxide layer can be used. The thickness of the reflective layer can be 0.1-0.5 microns. Preferably, the thickness of the reflective layer is 0.1-0.3 microns.
[0038] The preparation steps of the present application are as follows:
[0039] Step S1, printing graphics: printing graphics on the paper base material 6 by using intaglio or flexographic printing method;
[0040] Step S2, coating transfer paint: coating polyurethane paint or acrylic paint or transfer type laser paint on the PET base film, entering the oven to dry, controlling the peeling force of the transfer layer, which can meet the adhesion requirement of the subsequent mold pressing process, and can also separate from the base film;
[0041] Step S3, mold pressing: through the heating mold pressing or UV mold pressing process, a specific laser holographic layer is obtained on the side of the transfer paint layer away from the PET base film. In a preferred example, the heating mold pressing process adopts the laser film mold pressing technology, which is a technology of pressing specific patterns or characters on the surface of the material by using a mold under high temperature and high pressure. Therefore, one or more laser effects including cat eye, relief, dynamic graphics, 3D stereoscopic image and micro character can be arranged on the surface of the laser holographic layer, and the position of the laser effect can be specified as required.
[0042] Step S4, plating reflection layer: the material obtained in step S3 is used to vacuum evaporate a zinc sulfide reflection layer on the side of the specific laser holographic information layer away from the release layer of the PET;
[0043] Step S5, compounding: using a positioning compounding device, compounding glue is coated on the zinc sulfide reflection layer side of the material obtained in step S4, and dried, and the graphics side of the material obtained in step S1 is positioned and compounded. During the compounding process, the material obtained in step S4 is stretched to a certain length by a length stretching unit, so that the specific laser holographic effects such as cat eye and relief coincide with the graphic positions corresponding to the paper base material according to the design effect; this process can not only make the information content on the graphic layer 2 more obvious under the highlighting of the anti-fake structure laser effect, but also highlight the key information.
[0044] Step S7, aging: according to the process conditions of the compounding glue, the compounded roll material is placed in an oven for aging;
[0045] Step S8, film stripping and die cutting: first, the PET base film is stripped on the die cutting machine, and then positioning die cutting is performed according to the cursor set in the layout.
[0046] The utility model further provides a label which adopts the paper with laser effect. In a preferred example, the label is a beer label.
