Description

Anti-counterfeiting identification sticker with infrared laser variable invisible code

technical field

The utility model relates to an anti-counterfeiting identification sticker, in particular to an anti-counterfeiting identification sticker with an infrared laser variable invisible code, which can be uncovered and transferred. It is suitable for anti-counterfeiting of goods such as high-end cigarettes and liquor.

Background technique

At present, the anti-transfer anti-counterfeiting labels used on some high-end cigarettes and liquor are mostly composed of a varnish layer, a variable invisible code layer, a surface printing layer, a peeling layer, a hollow layer, a glue layer and a bottom paper layer. The variable invisible code layer is readable by scanners or mobile phones, and counterfeiters only need to generate variable information codes, which can be faked, and the authenticity cannot be verified. Most of the variable invisible codes are printed by inkjet printing or excited fluorescent printing, and the inks are available in the market and are easy to be counterfeited. Therefore, the authenticity cannot be verified, the anti-counterfeiting effect is poor, and it is difficult to achieve the purpose of anti-counterfeiting.

Utility model content

The problem to be solved by the utility model is to provide an anti-counterfeiting label with an infrared laser variable invisible code. This kind of identification sticker can verify the authenticity, has good anti-counterfeiting effect, and can achieve the purpose of anti-counterfeiting.

The above-mentioned problems to be solved by the present utility model are realized by the following technical solutions:

The anti-counterfeiting identification sticker with an infrared laser variable invisible code of the utility model comprises a bottom paper layer, and a glue layer is arranged on the top of the bottom paper layer. Its characteristics are: a hollow medium layer and a PET film layer are arranged on the glue layer, a varnish layer is arranged on the outside of the PET film layer, and a laser infrared variable invisible code and a surface printing layer are arranged on the outside of the varnish layer.

The surface printing layer is characters, numbers, pinyin, patterns, two-dimensional codes or bar codes.

The varnish layer is coated with water-based varnish.

The glue layer is uniformly coated with acrylic acid.

The backing paper layer is glassine paper with silicone oil on one side.

It can be seen from the above scheme that since there are a hollow medium layer and a PET film layer in sequence on the glue layer, there is a varnish layer on the outside of the PET film layer, and a laser infrared variable invisible code and a surface printing layer on the outside of the varnish layer.

When the PET film layer, the varnish layer and the laser infrared variable invisible code outside the varnish layer are uncovered together with the surface printing layer, the hollow medium layer on the glue layer can be seen, and the authenticity can be verified. Therefore, the utility model has good anti-counterfeiting effect and can achieve the purpose of anti-counterfeiting.

Description of drawings

FIG. 1 is a schematic diagram of an anti-counterfeiting identification sticker with an infrared laser variable invisible code according to the present invention.

Detailed ways

As shown in Figure 1, the anti-counterfeiting label with infrared laser variable invisible code of the present invention sequentially contains a base paper layer 6, a glue layer 5, a hollow medium layer 4, a PET film layer 3 and a varnish layer 2 from the inside to the outside, A laser infrared variable invisible code 11 and a surface printing layer 12 are arranged outside the varnish layer 2 .

in:

The surface printing layer 12 is characters, numbers, pinyin, patterns, two-dimensional codes or bar codes;

Described varnish layer 2 is water-based varnish;

The glue layer 5 is made of acrylic;

The hollow medium layer 4 is a hollow character;

The bottom paper layer 6 is glassine paper with silicone oil on one side.

The method for preparing the anti-counterfeiting identification sticker with the infrared laser variable invisible code of the present invention comprises the following steps in sequence:

Prepare the PET film layer 3 first;

Then, the water-based varnish is evenly coated on the outside of the PET film layer 3 with a flexo coater to obtain a varnish layer 2;

After that, use a digital printer to print the laser infrared variable stealth code on a part of the outer part of the varnish layer 2 to obtain the laser infrared variable stealth code layer 11 . And use a gravure printing machine to print characters, numbers, pinyin, patterns, two-dimensional codes or barcodes on the other part of the varnish layer 2 to obtain the surface printing layer 12;

After that, use a flexo coater to coat a layer of medium at the hollowed-out position on the back of the PET film layer 3 to obtain a hollowed-out medium layer 4;

Afterwards, use a coating machine to coat a layer of glue on the side of the base paper layer 6 with the silicone oil to obtain the glue layer 5;

Finally, the side of the bottom paper layer 6 with the glue layer 5 is attached to the outside of the hollow medium layer 4 to prepare an anti-counterfeiting label with an infrared laser variable invisible code.
