Printing-free protective gloss oil holographic anti-counterfeiting positioning direct-ironing gold blocking film and preparation method thereof

Abstract

The invention discloses a printing-free protective gloss oil holographic anti-counterfeiting positioning direct-ironing gold blocking film and a preparation method thereof, is used for surface anti-counterfeiting printing of glass, metal, ceramic and the like, and relates to the technical field of anti-counterfeiting package printing. The film comprises a base film layer, a release layer, an information coloring layer, a laser mould pressing layer, a vacuum aluminum coated layer and a gum layer which are arranged from inside to outside, the release layer is formed by spreading and drying release agent coating liquid; the information coloring layer is formed by spreading and drying information coloring coating liquid; the laser mould pressing layer adopts an anti-counterfeiting laser pattern formed by mould pressing; and the vacuum aluminum coated layer is formed on the surface of the laser mould pressing layer by vaporizing and evaporating aluminum wires uniformly under high-current vacuum. Compared with the prior art, the film has stronger high-temperature resistance, cracking resistance, discoloration resistance, alcohol resistance and water soaking resistance, holographic patterns or characters can be added according to customer requirements, the anti-counterfeiting function is achieved while the attractiveness of the product is improved, the technological process can be reduced, the anti-counterfeiting performance is improved, the processing technology is simplified, and the production time is saved.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting packaging and printing, and is used for anti-counterfeiting printing on surfaces such as glass, metal, ceramics, etc., and in particular relates to a non-printing protective varnish holographic anti-counterfeiting positioning direct hot stamping film and a printing-free protective varnish holographic anti-counterfeiting positioning direct The preparation method of bronzing film. Background technique [0002] Anodized aluminum bronzing foil has the characteristics of bright color, strong metallic texture, outstanding visual effect, etc., and can greatly improve the decoration grade of packaging. Now anodized aluminum has been widely used in various industries in life. The development of hot stamping machine manufacturing technology also indirectly drives the emergence of special new anodized aluminum. Alcohol-resistant holographic anti-counterfeiting positioning direct ironing anodized...

Problems solved by technology

[0003] At present, there are two ways of anodized aluminum bronzing foils available on the market for glass, metal, and ceramics. The first is to print the bronzing base oil on the water transfer printing backing paper, and then use the bronzing foil to press and heat the stamping machine on the printed surface. Burn out patterns or characters on the base oil, and then print protective varnish on the surface. The protective varnish has solvent type and UV / LED type. This protective varnish is used to protect the bronzing part to meet the requirements of alcohol resistance and water immersion. The disadvantage of the process is that the printed protective varnish will block and erode the gloss on the surface of the bronzing foil, and the edge of the protective varnish is larger than the bronzing part after being pasted on glass, ceramics and metals, causing ghosting, which seriously affects the appearance of the product; the second It is directly printed on the surface of glass, metal and ceramics with UV / LED or solvent-based hot stamping primer, and then wired hot stamping. Currently, the alcohol-resistant ordinary anodized aluminum hot stamping foil used for direct ironing is basically in its infancy, and hot stamping will occur Incomplete, large-area bronzing is prone to blistering, cracking, discoloration, alcohol resistance, and unqualified water immersion testing after baking. Therefore, a printing-free protective varnish holographic anti-counterfeiting positioning direct bronzing film is provided for glass, metal, It is of great significance to solve the above problems by anti-counterfeiting printing on surfaces such as ceramics
