Problems solved by technology

However, the label is produced in a composite way, and glue is used in the production process, which will have a certain impact on the quality of the product, which is not healthy and safe enough
In addition, the anti-counterfeiting information of the gasket is not unique, and the anti-counterfeiting strength is relatively low

Embodiment 1

[0040] The preparation method of the described image comparison physical foam gasket, the specific steps are as follows:

[0041] 1) Choose a BOPP film with a thickness of 40 μm.

[0042] 2) On the BOPP film, use a flexo printing machine to position and print UV varnish with metal particles, dry it by UV lamp drying, and then position and print two-dimensional code information to form a printing layer 4; the color of metal particles can be selected A variety of colors can also be used, and the addition ratio of metal particles in the varnish is 5.3%.

[0043] 3) The BOPP film of the printed layer 4 is prepared, and the collector is used to collect pictures and associate them. The collected information forms a data folder, and the collected pictures are uploaded to the server to establish a relationship between the pictures and the QR code.

[0044] 4) The BOPP film of the printed layer 4 is bonded together with the physical foaming material by coating the PE film. When coatin...

Embodiment 2

[0049] The preparation method of the described image comparison physical foam gasket, the specific steps are as follows:

[0050] 1) Choose a single-sided corona BOPP film with a thickness of 30 μm.

[0051] 2) Use a digital machine to print random particles and two-dimensional code information on the BOPP film to form a printing layer 4 . There is a 1mm gap between the two-dimensional code and the random particle printing area to ensure that the random particle points do not affect the grade of the two-dimensional code and ensure the reading rate.

[0052] 3) The BOPP film of the printed layer 4 is prepared, and the collector is used to collect pictures and associate them. The collected information forms a data folder, and the collected pictures are uploaded to the server to establish a relationship between the pictures and the QR code.

[0053]4) The BOPP film of the printed layer 4 is bonded together with the physical foaming material by coating the PE film. When coating, ...

Abstract

The invention relates to the technical field of anti-counterfeiting products, in particular to an image comparison physical foaming gasket and a preparation method thereof. The image comparison physical foaming gasket comprises a first lamination layer, a foaming layer, a second lamination layer, a printing layer and a BOPP (biaxially-oriented polypropylene) film layer which are sequentially arranged from top to bottom, wherein the printing layer information comprises a two-dimensional code and randomly distributed particle points, and a corresponding relation exists between the two-dimensional code and the randomly distributed particle points. According to the invention, the two-dimensional code is combined with the random particles, the anti-counterfeiting feature of each gasket is unique, the imitation difficulty is high, the identification is simple, and the anti-counterfeiting effect is good. According to the preparation method, a film spraying mode is adopted for production, glue is not adopted, the product is healthier and safer, waste materials in the production process can be recycled for secondary utilization, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting products, in particular to an image comparison physical foam gasket and a preparation method thereof, which are applicable to the fields of liquor, cosmetic packaging and the like. Background technique [0002] Physical foam gaskets are widely used in liquor, cosmetics and other bottle caps to seal and prevent leaks. This type of gasket basically does not have the function of anti-counterfeiting. [0003] Chinese patent CN 105083736 A discloses an anti-counterfeiting bottle cap gasket and a preparation method thereof. The anti-counterfeit bottle cap gasket is a foam layer, the first adhesive layer, the release layer, the holographic information layer, the aluminum layer, the second adhesive layer and the transparent cover layer connected in sequence from top to bottom; the aluminum layer is provided with a vacancy , a digital layer and a printing layer are juxtaposed inside the vacan...
