Abstract

The utility model relates to an anti-forging complex film of a hidden type, which comprises a non-transparent raster base film (1), wherein a disengaging film (2) is coated on the base film, a transparent protecting film (3) is arranged on the disengaging film, an anti-reflection film (4) is arranged on the transparent protecting film, a brightening film (5) is arranged on the anti-reflection film and is connected with a transparent oil ink film (7), and a raster (6) is stamped at the interface of the brightening film and the transparent ink film. The complex film is covered on a protected body. Before the non-transparent raster base film is not uncovered, the anti-forging complex film has secrecy function. After the non-transparent raster base film is uncovered, anti-forging patterns and anti-forging numerical codes and marks on the oil ink film can be clearly observed. The complex film can make real things and products not juggled and forged.

Description

Block the formula anti-counterfeiting compound film

The utility model relates to a kind of formula anti-counterfeiting compound film that blocks.

Existing reflection hologram anti false film (anti-false sign) roughly comprises transparent basement membrane, polyester (PET) for example, Polyvinylchloride (PVC) etc., evaporation layer of aluminum on the basement membrane, form holographic grating through mold pressing, it below the holographic grating adhesive sticker, a multiple silicon paper after the anti-counterfeiting compound film of this version is torn silicon paper, sticks on a certain product on the adhesive sticker, with pattern behind its diffraction as anti-false sign, but this anti-counterfeiting compound film still has the following disadvantages, and for example: basement membrane scratches easily, is that single hologram is false proof, anti-false sign exposes etc., cause being forged easily, therefore, be necessary to provide a kind of novel anti-counterfeiting compound film.

The purpose of this utility model provides a kind of formula anti-counterfeiting compound film that blocks, this film has a barrier bed, has confidentiality, open barrier bed when needing and just can see anti-false sign, and after opening, the nexine light transmission is good, rub resistance, the clear patterns of anti-false sign has the multiple signs such as false proof number on the ink film again, and difficult quilt is distorted forgery.

For achieving the above object; the utility model is by the following technical solutions: the formula anti-counterfeiting compound film of blocking comprises: scribble on opaque light grid base film [1], the basement membrane and break away from film [2]; breaking away from the film is transparent protective film [3]; it on the transparent protective film anti-reflection film [4]; it on the anti-reflection film brightness enhancement film [5]; brightness enhancement film [5] is joined with clean oil ink film [7], and their interface impresses a grating [6].

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 the utility model structural representation

Another embodiment sectional drawing of Fig. 2 the utility model

Among Fig. 1,1 is opaque light grid base film, is the carrier of each composite bed, can adopt polyester (PET), Polyvinylchloride (PVC), polypropylene plastics grating films such as (P.P), or grating paper, and these gratings can be made with mould pressing method, has to decorate and antiforge function.2 for breaking away from film, and it is multiple on opaque light grid base film, for example adopts waxing; breaking away from the film is transparent protective film 3, and its hardness and glassy phase are worked as, and can adopt the plating layer of silicon dioxide; thickness is 1000～4000 dusts, and 1338 dusts preferably can make that the surface is not scratched, corrosion etc.Be anti-reflection film 4 on the transparent protective film, purpose is to increase sharpness, and it can adopt three layers of composite membrane; that is: zirconium dioxide film, thickness 2675 dusts, di-aluminium trioxide film; thickness 1338 dusts; silicon dioxide film, thickness 6688-13380 dust, purpose is to reduce the reflected light loss; increase brightness; light transmission rate reaches more than 99.9%, is brightness enhancement film 5 on the anti-reflection film, and it is used to increase brightness of image; about its brightness can double; can adopt and aluminize, about 30～40 dusts of thickness, but also titanizing; about 30～40 dusts of thickness; be clean oil ink film 7 on the brightness enhancement film, available commercially available CGC-F1 series safety ink is as shining with cash inspecting machine; can produce fluorescence of all kinds; the also ink-jet sign indicating number of available non-fluorescence or general printing, it is digital that the clean oil ink film can make anti-counterfeiting compound film increase; anti-false signs such as fluorescence are the grating 6 that a pressurization forms between brightness enhancement film and clean oil ink film; can adhesive sticker or hot melt adhesive below the ink film; or first gluing not, gluing voluntarily when to be used, topped again on protected body.

Among Fig. 2; in order to increase antifalse effect; a multiple ply of paper on the glued membrane 8 of coated outside clean oil ink film 7; this glued membrane available polyethylene has the composite membrane of paper to be combined on the protected body by adhesive sticker on the paper (the silicon ply of paper is arranged again) or melt viscosity again, also can be gluing in advance not on the paper film; gluing voluntarily when needing; topped again on protected body, can on paper, do some explanation or stamped signature etc. like this, enlarged the antiforge function of anti-counterfeiting compound film.

During use, above-mentioned composite membrane is attached on the protected body, protected body contains seal prison, tax chapter or certification etc., and the observer throws off opaque light grid base film by breaking away from film, can see anti-false signs such as optical grating diffraction pattern, fluorescence, bar code, special number.

The utility model advantage: have opaque light grid base film, can rise and maintain secrecy and anti-fake effect, when After the basement membrane of composite membrane was opened, the nexine light transmission was good, rub resistance, and the optical grating diffraction clear patterns, also Have the anti-false signs such as fluorescence falsification preventing picture and text, bar code, special number, adopt this composite membrane can make very Part and product can't be distorted, forge.
