Description
Technical Field
The invention belongs to the technical field of labels, and particularly relates to an anti-counterfeit label and application thereof.
Background
At present, the anti-counterfeiting mark becomes an indispensable means for maintaining the legitimate rights of a plurality of commodity enterprises, the anti-counterfeiting mark technology is continuously upgraded and evolved, the digital anti-counterfeiting technology is widely applied to the fields of packaging, logistics and the like after a period of development, and the market also puts higher and higher requirements on the anti-counterfeiting property and the aesthetic property of the anti-counterfeiting mark.
The laser powder is made up by using electroplating material with very high brightness through the processes of precision cutting and pulverizing, and possesses rich colour, bright colour and corrosion resistance and temperature resistance. With the continuous progress of the pulverizing equipment, the particle size of the laser powder can reach several micrometers to dozens of micrometers.
The laser powder is applied to printing, so that the effect of enhancing and enriching printing colors can be achieved, and the anti-counterfeiting effect can be achieved. The existing laser anti-counterfeiting label is a local laser holographic label, the laser effect is a surface or an area surface, and the label has no layering sense, so that the anti-counterfeiting label is not attractive and is very easy to copy by counterfeiters, and the anti-counterfeiting performance of the label is lost; secondly, the existing laser anti-counterfeit label exposes the ink in the air, so that on one hand, the ink marks can be damaged by careless friction, and on the other hand, the ink has large smell and can also volatilize, thus being not friendly to the environment.
Disclosure of Invention
The first technical problem to be solved by the invention is as follows:
an anti-counterfeit label is provided. In the anti-counterfeiting label, the laser powder is placed in the multi-level bonding layer and separated by the transparent resin layer, so that the anti-counterfeiting effect is improved.
The second technical problem to be solved by the invention is:
the application of the anti-counterfeiting label is provided.
In order to solve the first technical problem, the invention adopts the technical scheme that:
an anti-counterfeit label comprises a first resin layer, an adhesive layer, a second resin layer and a release layer which are sequentially stacked;
at least one printing ink print is arranged between the first resin layer and the adhesive layer;
the first resin layer and the second resin layer are transparent layers;
and laser powder is independently arranged in the ink print, the adhesive layer and the release layer respectively.
The radium-shine effect is in the printing ink trace the gluing agent layer appear from the type layer to the naked eye is observed from any one side of antifalsification label, can both see the radium-shine effect that appears regional point distribution, looks at from the type layer in-process promptly from first resin layer, can obviously see out among the antifalsification label, keeps away from the radium-shine effect on one side on type layer stronger, is close to the radium-shine effect on one side on type layer weaker, promptly first resin layer with the radium-shine effect in second resin layer middle part is stronger, thereby shows the layering of radium-shine effect.
Based on this, in the antifalsification label, place laser powder in multilayer anchor coat, divide with transparent resin layer again, build the radium-shine effect of regional point distribution, this makes the antifalsification label be difficult to by forger's high accuracy reproduction, even forger utilizes current duplicator to duplicate the label, after the completion of duplicating, only need with light irradiation the antifalsification label, observe the change of reflection light, the label that can see the duplication has great difference with the genuine label in the vision, the user only relies on the naked eye to distinguish, so improved product security. Laser powder is skillfully added into the ink print, and a printed pattern with a certain laser effect can be presented through printing.
The adhesive layer is an adhesive layer adhered with the first resin layer and the second resin layer, and the first resin layer and the second resin layer are connected together through the adhesion, cohesion and the like of an interface. And the laser powder in the adhesive is added into the adhesive in a grinding and dispersing way.
According to one embodiment of the invention, the surface of the release layer is coated with a release agent, and the release agent is filled with laser powder. And a certain laser effect is embodied on the release layer by a printing or coating method so as to further enhance the laser effect.
And adhesive sticker and release paper are also arranged below the release layer. The thickness of the self-adhesive and the release paper has no special requirement.
The release paper is silicone oil paper.
The solid content of the release agent is 15-30%, and 1-5% of laser powder is added into the release agent.
According to one embodiment of the invention, the solid content of the ink in the ink print is 15-30%.
The laser powder with the content of 1-5% is added into the ink.
The laser powder adopts standard hexagonal glitter powder with high flash, high brightness and obvious mirror effect.
According to one embodiment of the invention, the thickness of the anti-counterfeiting label is 80-100 μm.
According to an embodiment of the present invention, the thickness of the release layer is 1 to 2 μm.
According to one embodiment of the present invention, a thickness ratio of the first resin layer, the ink print, and the second resin layer is 12 to 25:1 to 2:12 to 25. Under the thickness ratio, the laser effect can reach the best.
Laser powder is dispersed in the ink print, so that the ink has the effect of gorgeous light while reflecting the original color; and secondly, the ink dispersibility is better.
According to one embodiment of the invention, the first and second resin layers are flexible barriers. Play right on the one hand antifalsification label's protecting effect, further, avoid the printing ink trace to expose outside by wearing and tearing, prevent laser powder on the one hand again and spill, on the other hand the flexible characteristic of first resin layer for the user can tear as required first resin layer, thereby direct contact printing ink trace, for example with antifalsification label when scraping the prize label, the user can conveniently tear first resin layer, then scrape the printing ink trace.
According to one embodiment of the present invention, the raw materials of the first resin layer and the second resin layer are independently selected from at least one of polyethylene terephthalate, polybutylene terephthalate, and polyethylene terephthalate-1, 4-cyclohexanedimethanol ester.
According to one embodiment of the present invention, the diameter of the laser powder is 3 to 30 μm.
In another aspect, the invention also relates to the application of the anti-counterfeiting label in product packaging. The conventional process flow of the label is as follows: printing, compounding, coating and die cutting, the ink, the release layer and the adhesive added with the laser powder can be realized without changing technological parameters, and the operation is simple and convenient.
One of the technical solutions has at least one of the following advantages or beneficial effects:
1. laser powder is placed in the multilayer combined layer and is separated by the transparent resin layer, so that the laser effect of area point distribution is created, and the anti-counterfeiting label is difficult to be copied by counterfeiters with high precision;
2. the first resin layer and the second resin layer are flexible interlayers. Play right on the one hand antifalsification label's protecting effect, further, avoid the printing ink trace to expose outside by wearing and tearing, prevent laser powder on the one hand again and spill, on the other hand the flexible characteristic of first resin layer for the user can tear as required first resin layer, thereby direct contact printing ink trace, for example with antifalsification label when scraping the prize label, the user can conveniently tear first resin layer, then scrape the printing ink trace.
