Embodiment 1

[0023] Example 1. PET plastic film is used as the substrate layer, which is equivalent to the base film used in production. A transparent release coating layer or release layer is coated on the substrate layer; the release layer coating adopts a weight ratio of polyurethane emulsion 35 %, acrylic emulsion 15%, deionized water 25%, isopropanol 25% mixed and made, quantitatively coated with 220 mesh anilox roller, and then dried, drying temperature 80 ℃, operating linear speed 80 m / min.

[0024] Coat the holographic laser laser molding coating layer on the release layer. The coating can be 20% acrylic resin, 10% cellulose acetate butyl cellulose resin, 30% methyl ethyl ketone, 30% ethyl acetate, 10% isopropanol by weight. Mixed and dissolved. Use 200 mesh anilox roller for quantitative coating, the temperature during drying is 70℃, and the running speed is 80m / min.

Embodiment 2

[0029] Example 2. The laser base film of Yunmeng First Company was used as the substrate layer, and the transparent release coating layer, namely the release layer, was coated on the substrate layer; the coating used was 47.5% by weight of polyurethane emulsion and 2.5% by weight of acrylic emulsion. %, 25% deionized water and 25% isopropanol are mixed. The coating used in this layer can be colored by adding pigments or dyes, but the coating is still transparent. The layer is coated with a coater. The specific process parameters of coating the release layer are as follows: Quantitative coating with 220 mesh anilox roller , The drying temperature is 120 ℃, and the operating linear speed is 125 m / min; this layer requires good film release performance and complete film forming performance.

Abstract

The invention relates to a preparation method of a dielectric-film diversion material of high vacuum vapor deposition; the preparation method comprises the following steps: A. a plastic film base-material layer is adopted and coated with a transparent demoulding coating layer; B. a release layer is coated with a holographical laser molding coating layer so as to form an imaging layer; C. molding is carried out on the imaging layer so as to form a holographical laser die pressing layer with anti-counterfeiting performance; D. vacuum vapor deposition is carried out on the molding layer so as to form a dielectric coated layer; E. an adhesive layer is coated on the vapor deposition dielectric layer, and paper or plastic film are stuck to the adhesive layer to form a sheet layer; F. the film is peeled from a release layer so as to obtain the diversion laser dielectric paper or plastic film. The dielectric film diversion material of high vacuum vapor deposition has not only the performance of anti-counterfeiting and anti-oxidation, but also ideal performance of air resistance, humidity resistance and wearing resistance, etc. by coating a functional paint in subsequent processing and is an ideal anti-counterfeiting material.

Description

Technical field [0001] The present invention designs a packaging anti-counterfeiting composite material. More specifically, the present invention relates to a high-vacuum evaporation medium film transfer material. Background technique [0002] At present, the anti-counterfeiting films used for packaging and decoration generally use BOPP, PET, PVC, CPP and other base films, using vacuum aluminum plating, molded laser laser layer, composite printing and other processing techniques to give the film a colorful dynamic pattern and a metalized whole The effect and the corresponding barrier and fragrance preservation. However, the opacity of its aluminized affects its development toward transparent laser anti-counterfeiting packaging and decoration materials. If you need to prevent forgery and clearly see the contents of the packaging, such as ID cards, passports, cigarette films, etc., you cannot use this Laser anti-counterfeiting aluminized film for packaging. Summary of the inventio...
