Embodiment Construction
[0012] In a vacuum device, an aluminum layer is vapor-deposited on one side of a flexible insulating film made of materials such as thermosetting resin, and the coating thickness is preferably 300 to 500 angstroms. Thereafter, the aluminum-plated insulating film is taken out from the vacuum device, and printed on the aluminum-plated surface of the insulating film by a printing method known in the art, and a polyamide ink protective layer of predetermined pattern or pattern is formed thereon. The predetermined figure or pattern corresponds to the desired figure or pattern. Then, the insulating film is introduced into an etching tank equipped with sodium hydroxide, and the aluminum layer outside the area covered by the polyamide ink protective layer is etched away to obtain the required metal pattern or pattern on the aluminum-plated surface of the insulating film; Apply transparent or translucent inks to protect the pattern layer prepared on the film.

Abstract
The invention discloses a card paper packaging material with local holographic effect and a manufacturing method thereof, which includes steps: films are provided; a metal coating is evaporated in vacuum on the film surface; a chemistry resistance corrosion protective layer is printed on the metal coating, the shape of which is corresponding to the needed metal graphic or design; the metal coating outside the protective covered area on the film surface is removed by chemical corrosion, and the needed graphic or design is obtained on the film surface; the transparent or semitransparent ink is coated on the metal plated surface of the film; pigments are printed on the metal plated surface of the film according to the card paper color; the metal plate is evaporated in vacuum on the paint printing surface of the film again; the obtained film and the card paper is combined, or the graphics is transferred to the card paper by the traditional transfer technique. The invention makes the holographic graphics on the metal card paper directly, thus obtaining novel composite packaging material. Compared with the traditional local holographic gold blocking technique, the processing cost is reduced and the production efficiency is improved sharply.
Description
technical field [0001] The invention relates to a cardboard packaging material and a manufacturing method thereof. Background technique [0002] Cardboard packaging materials can be widely used in the outer packaging of various products such as color boxes and cardboard. In the production process of traditional cardboard packaging boxes, metallization treatment such as bronzing treatment is required to obtain a certain visual effect, but this bronzing treatment requires higher processing costs and longer processing time. Contents of the invention [0003] The object of the present invention is to provide a cardboard packaging material with low cost and high production efficiency and a production method thereof. [0004] The manufacturing method of the cardboard packaging material of the present invention comprises the steps of: providing a film; vacuum-depositing a metal coating on the surface of the film; printing a chemical corrosion-resistant protective layer on the me...
