[0028] DETAILED DESCRIPTION
[0029] 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.
[0030] The utility model provides a paper with laser effect, including the transfer layer 1, the figure layer 2, the first composite adhesive layer 3, the reflection layer 4, the laser holographic layer 5, the second composite adhesive layer 6 and the paper base material 7 of the layering from top to bottom, in one preferred example, the figure layer 2 is the printed figure layer.
[0031] The laser holographic layer includes holographic layer main part and the anti-fake structure that is arranged in the holographic layer main part, the anti-fake structure is arranged in one local area or a plurality of local areas in the holographic layer main part, specifically, the anti-fake structure is arranged in one local area or a plurality of local areas in the holographic layer main part randomly.
[0032] The transfer layer 1 includes polyurethane coating, acrylic coating or transfer type laser coating, the first composite adhesive layer 3 includes solvent type dry composite adhesive layer or water-based dry composite adhesive layer, the reflection layer 4 includes aluminum layer, zinc sulfide layer, silica layer or titanium dioxide layer, the second composite adhesive layer 6 includes solvent type composite adhesive layer or water-based composite adhesive layer, such as dry composite adhesive layer, wet composite adhesive layer, hot melt adhesive layer, ordinary film adhesive layer, preferably, is solvent type dry composite adhesive layer, water-based dry composite adhesive layer or water-based wet composite adhesive layer.
[0033] It is worth noting that the laser holographic effect of the existing beer label, there is no laser effect scheme such as cat eye, relief, dynamic figure, 3D stereoscopic image, microtext in the local specified area, because the beer label generally adopts 60-90g / m2 paper, these paper is relatively thin, when adding specific laser effect in any or specified area using similar cigarette package, wine box, cosmetics, toothpaste box scheme, the dimensional change in longitudinal and transverse direction is relatively large in the positioning holographic paper production process, is unstable, the overprint accuracy in the offset printing process is very poor, the yield is very low, and batch production is impossible, but the structure of the utility model is not directly offset printed on the paper base material, but printed on the PET base film transfer coating layer, then the printed PET film is bonded and compounded with the layered structure with laser holographic layer, and finally bonded and compounded with the paper to form, therefore, even if the paper base material adopts 60-90g / m2 paper base material, such as the 60-90g / m2 wet strength paper or the copperplate paper, the utility model also has the advantages of high precision, high yield and quantifiable production.
[0034] In a preferred embodiment, the laser holographic layer 5 is a specific laser holographic layer, and the anti-counterfeiting structure in the specific laser holographic layer includes one or more of cat eyes, reliefs, dynamic graphics, 3D stereoscopic images, microtext, and / or patterns.
[0035] As Figure 1 The information content (which can be referred to as a positioning printed pattern 8) on the graphic layer 2 is located at a position matched with the position of the anti-counterfeiting structure (which can be referred to as a positioning optical pattern 9). That is, the specific laser holographic effects such as cat eyes and reliefs in the anti-counterfeiting structure coincide with the corresponding graphic positions according to the design effects. This feature can make the information content on the graphic layer 2 more obvious under the highlighting of the laser effects of the anti-counterfeiting structure, so that the information content is more easily perceived by the user, that is, it plays a role in highlighting key information.
[0036] In addition, the structure of the present application is more complex than the existing full-plate plain color rainbow holographic, full-plate light column holographic, or randomly distributed laser holographic effect label. The local holographic effect technology is more difficult to achieve and is used by a smaller number of people. Therefore, the present application also has better anti-counterfeiting effect.
[0037] The preparation steps of the present application are as follows:
[0038] Step S1, coating transfer paint: coating polyurethane paint or acrylic paint or transfer laser paint on the non-corona surface of the first PET base film, and entering the drying channel for drying. The coating can be easily separated from the PET film, and has good friction resistance;
[0039] Step S2, printing graphics: on the side of the transfer paint layer, using intaglio printing or offset printing or flexographic printing to print graphics;
[0040] Step S3, coating transfer information layer paint: coating transfer laser paint on the non-corona surface of the second PET base film, and entering the drying channel for drying. The coating can be easily separated from the PET film, and the peeling force is less than that of the coating obtained in step S1;
[0041] Step S4, molding: the material obtained in step S3 is heated and molded on the side of the transfer information layer away from the second PET base film, to obtain a laser holographic layer. In a preferred embodiment, the heating and molding process uses laser film molding technology, which is a technology for pressing a specific pattern or text on the surface of a material under high temperature and high pressure. Therefore, the laser holographic layer can be provided with one or more laser effects including cat eyes, reliefs, dynamic graphics, 3D stereoscopic images, and microtext, and the positions of the laser effects can be specified as needed.
[0042] Step S5, plating a reflective layer: the material obtained in step S4 is used to vacuum deposit an aluminum reflective layer on the side of the specific laser holographic layer away from the second PET base film by using a vacuum aluminum plating machine, and the thickness is 100-200nm. Preferably, the thickness of the aluminum reflective layer is 100-200nm. Left and right;
[0043] Step S6, dry compounding (I): a positioning compounding device is used to coat dry compounding glue on the side of the material obtained in step S2 with graphics, dry the graphics, and position and compound with the aluminum reflective layer side of the material obtained in step S5. During the compounding process, the material obtained in step S5 is subjected to length stretching by using a length stretching unit, so that the cat eye, the embossing and other specific laser holographic effects coincide with the corresponding graphic positions according to the design effect; this process can make the information content on the graphic layer 2 more obvious under the highlighting of the anti-fake structure laser effect, so that the information content is more easily perceived by the user, that is, the function of highlighting the key information is achieved.
[0044] Step S7, aging: according to the process conditions of the dry compounding glue, the roll material after dry compounding is placed in an oven for aging;
[0045] Step S8, film stripping and compounding (II): the material obtained in step S7 is stripped of the second PET base film on a compounding machine, and compounding glue is coated on the transfer information layer side to be compounded with a paper base material, and then dried;
[0046] Step S9, film stripping and die cutting: the first PET base film is first stripped on a die cutting machine, and then positioning die cutting is performed according to the cursor set in the layout.
[0047] The utility model further provides a label which adopts the paper with laser effect.
