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) Select a BOPP film with a thickness of 40 μm.

[0042] 2) Use the flexo printing machine to position and print the UV varnish with metal particles on the BOPP film, dry it by UV lamp drying, and then position and print the two-dimensional code information to form the printing layer 4; the color of the metal particles can be One can also use a variety of colors, 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 images, the collected information forms a data folder, and the collected images are uploaded to the server to establish an association relationship between the images and the two-dimensional code.

[0044] 4) Bond the BOPP film of the prepared printing layer 4 with the physical foam material by coating the PE film. When coating th...

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) Using 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 images, the collected information forms a data folder, and the collected images are uploaded to the server to establish an association relationship between the images and the two-dimensional code.

[0053]4) Bond the BOPP film of the prepared printing layer 4 with the physical foaming material by coating the PE film. When coating th...

Abstract

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. The image comparison physical foam pad of the present invention includes the first coating layer, the foaming layer, the second coating layer, the printing layer and the BOPP film layer arranged in sequence from top to bottom; wherein, the printing layer information Including two-dimensional codes and randomly distributed particle points, there is a corresponding relationship between two-dimensional codes and randomly distributed particle points. The present invention combines two-dimensional codes with random particles, the anti-counterfeit features of each pad are unique, difficult to imitate, easy to identify, and good anti-counterfeiting effect; the preparation method of the present invention is produced by laminating, without Glue, the product is healthier and safer, and the waste in the production process can be recycled for secondary use, energy saving and environmental protection.

Description

technical field [0001] 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, which are suitable for the fields of liquor, cosmetic packaging and the like. Background technique [0002] Physical foam gaskets are widely used in bottle caps such as liquor and cosmetics to seal and prevent leakage. This type of gasket basically has no anti-counterfeiting effect. [0003] Chinese patent CN 105083736 A discloses an anti-counterfeiting bottle cap gasket and a preparation method thereof. The anti-counterfeiting bottle cap gasket is a foam layer, a first adhesive layer, a release layer, a holographic information layer, an aluminum coating layer, a second adhesive layer and a transparent cover layer connected in sequence from top to bottom; the aluminized layer is provided with a vacancy part , a digital layer and a printing layer are arranged side by side inside th...
