Embodiment Construction

[0018] The present invention is described in detail below in conjunction with embodiment.

[0019] According to a kind of variable color anti-counterfeit composite film manufacturing method of the present invention, take plastic film as base layer, adopt following steps:

[0020] (1) Superimpose the color-changing layer on the base layer, also known as the coloring layer: mix the binder containing the photosensitive material evenly, process it into a viscous paint, apply it evenly on the surface of the base film by anilox roller printing, and pass through five stages It is baked and dried in a type oven to increase the brightness and fullness of the product, and the color will be reversed under ultraviolet light and sunlight. 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 is 120m / min.

[0021] During the production process, the miscibility of the photosensitive material and the binder, and the viscosity of...

Abstract

The invention relates to a variable-color anti-counterfeiting composite film production method. Using a plastic film is as a base layer, the method includes: superposing a color variation layer on the base layer by means of uniformly mixing a connecting material containing a photosensitive material, processing the mixed material into an adhesive coating, uniformly coating the adhesive coating on the surface of the base layer film through coated printing of an anilox roller, drying through baking of a five-stage baking oven so as to improve brightness and plumpness of a product and enabling the color to generate inverse variation under ultraviolet and solar irradiation; superposing a printed layer on the color variation layer by means of printing characters and patterns on the surface of the coating through a gravure printing machine, adjusting an impression cylinder by adjusting a scraper and controlling drying temperature of printing ink; slitting and rewinding. According to the variable-color anti-counterfeiting composite film production method, a traditional composite technology and variable-color electron transfer type organic compounds are integrated to form a novel variable-color anti-counterfeiting composite film which is convenient to use, has an anti-counterfeiting function and is not easy to counterfeit.

Description

technical field [0001] The invention relates to a composite film for packaging, in particular to a method for making a color-changing anti-counterfeiting composite film. Background technique [0002] At present, the composite film is widely used in packaging. Its function is relatively single, and its anti-counterfeiting is not strong. After use, the product is easy to be counterfeited. [0003] In view of this, seeking a color-changing anti-counterfeiting composite film and its manufacturing method has become the goal pursued by those skilled in the art. Contents of the invention [0004] The task of the present invention is to provide a method for making a color-changing anti-counterfeiting composite film, which solves the problems in the above-mentioned prior art. The photosensitive color-changing anti-counterfeiting composite film made by this method has the functions and characteristics of ordinary composite films. The feature of changing color, thus increasing the a...
