[0004]
In order to solve the technical problems existing in the background technology, the present invention provides a positioning aluminized anti-counterfeiting hot stamping foil and a preparation method thereof, which solves the defects of many procedures and large pollution in the existing aluminizing process in the aluminum washing process, and also solves the problem of The perfluorinated shielding liquid used in the existing hollow aluminum plating process has low surface energy, has a perfluorinated structure, and has incompatible characteristics with other conventional inks, so the perfluorinated shielding liquid is easy to cause in the subsequent process. False printing or no good adhesion when hot stamping after coating the back glue

Embodiment 1
[0035] A method for preparing an aluminized anti-counterfeiting hot stamping calyx of the present invention, comprising the following steps:
[0036](1) 20μm thick, 710mm wide biaxially oriented polyester film is selected as the base film, and the release agent is composed of liquid water wax, pure water and absolute ethanol. Take German ACMOS / 101-5017 liquid water wax 0.5kg, pure water 3.5kg, anhydrous ethanol 3.5kg, 100r / min After stirring for 5min, the anilox roller hole is 180 mesh, the reticulated coating machine is used on the base film to coat the release agent, the speed is 120m / min, the drying channel temperature is 80-100-130-150-100 °C, and the release layer is formed on the base film;
[0037] (2) Coating the laser information layer at the release level of the base film, roller coating, 140 mesh coated anilox roller, drying channel temperature 80-100-140-140-100 °C, vehicle speed 80m / min, laser information coating drying after drying is 0.8g / m 2 , in the molding gravur...

Abstract
The invention relates to a positioning aluminum-plated anti-fake hot stamping foil which comprises a base material layer, a release layer, a laser information layer, a positioning aluminum-plated layer, a printing image-text information layer and a back adhesive layer which are sequentially stacked from top to bottom. The positioning aluminum plating layer is obtained by printing fluorine-containing protective liquid on the laser information layer and synchronously performing vacuum aluminum plating. The invention relates to a positioning aluminizing anti-counterfeiting hot stamping foil and a preparation process of the positioning aluminizing anti-counterfeiting hot stamping foil, which solve the defects of more procedures and serious pollution in an aluminum washing process in the existing aluminizing process, and also solve the problem that a perfluorinated shielding liquid used in the existing hollow aluminizing process has the characteristics of low surface energy, perfluorinated structure and immiscibility with other conventional printing ink, so that the anti-counterfeiting hot stamping foil cannot be easily formed. And the defect that the perfluorinated shielding liquid is easy to cause incompact printing in the subsequent process or no good adhesive force during hot stamping after back glue coating is overcome.
Description
Technical field [0001] The present invention belongs to the field of anti-counterfeiting materials, specifically relates to a positioning aluminized anti-counterfeiting hot stamping foil and preparation method thereof. Background [0002] Hot stamping foil belongs to a kind of packaging materials, with the function of packaging decoration, under the blessing of modern printing technology, hot stamping foil and anti-counterfeiting technology combined, making it more of an anti-counterfeiting material. With the development of packaging technology and the demand for anti-counterfeiting of products, the integration of anti-counterfeiting and packaging has become a new trend. The existing hollowed-out aluminum-plated hot stamping foil mainly adopts the aluminum washing process after aluminum plating, a large amount of wastewater is generated during the aluminum washing process, the production process is more, the printing and washing aluminum ink and the production equipment and equip...
