Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] see figure 1 , a scratchable laser holographic anti-counterfeiting foil manufacturing method of the present invention comprises the following steps:

[0029] (1) Superimpose the release layer on the base layer: After dissolving the high-brightness and transparent synthetic solid wax with a solvent, it is evenly coated on the polyester film by an anilox roller, and dried in a five-stage oven. The temperature sequence of the five-stage oven is 100°C-110°C-120°C-130°C-120°C, the pressure is 20pa, and the speed is 150m / min.

[0030] (2) Superimpose the laser molded color layer on the release layer: evenly coat the dissolved resin on the surface of the release layer through an anilox roller, and bake and dry in a five-stage oven. The temperature sequence of the five-stage oven is 110°C-120°C-130°C-140°C-150°C, the pressure is 20pa, and the speed i...

Abstract

The invention relates to a method for manufacturing scratchable laser holography anti-fake foil, taking a plastic polyester film as a substrate layer, comprising the following steps of: superposing a release layer on the substrate layer; superposing a laser molding color layer on the release layer, comprising evenly coating the dissolved resin on the surface of the release layer, and baking and drying via a five-section oven; superposing a holography anti-fake molding layer on the laser molding color layer, comprising forming visual laser patterns and information by a laser information layer via a roller coated with laser engraved laser plates; superposing a printing layer on the holography anti-fake molding layer; superposing a vacuum aluminized coating layer on the printing layer, comprising heating an evaporator to 1400-1500 DEG C, cooling the high-purity aluminum wires continuously sent to the evaporator into aluminum steam, evenly spraying aluminum molecules on the surface, and forming an aluminum film; and superposing a gum layer on the vacuum aluminized coating layer. The product manufactured by the method provided by the invention is high in printing production efficiency and is scratched once; the product has certain anti-fake effects and can replace a traditional method for scratching ink by a squeegee.

Description

technical field [0001] The invention relates to anti-counterfeiting foil technology, in particular to a method for making scratchable laser holographic anti-counterfeiting foil. Background technique [0002] The film materials used in the laser holographic film are mainly PVC, PET, OPP, BOPP and other plastic films. , green, black, etc., are widely used in the printing and packaging industry, and can be used as stickers for various purposes, carton packaging, clothing tags, laser holographic glass materials, etc. The laser holographic film can be used for interior decoration, lettering or advertising decoration after back-adhesive. Among them, the laser holographic BOPP film can be widely used in tobacco, alcohol, beverage, and food packaging after compound treatment. It not only gives the packaging anti-counterfeiting function, but also improves the packaging grade. [0003] The application of laser holographic marking in the field of packaging and printing is increasing ...
