Abstract
At present, the aluminum foil imitating effect of aluminum-plated paper is generally realized by a matt transfer paint coating method, the mesh points of matting powder are obvious; and as compared with the aluminum foil, the visualized metal texture is poor, the matt paint coating process is low in yield, and the aluminum foil imitating matt effect of the surface is influenced by matting powder coating legging, tailing, shadowing and the like. The invention discloses a production process of a BOPP (Biaxially Oriented Polypropylene) matt laser film for the aluminum-foil-imitating aluminum-plated paper. The production process sequentially comprises the steps of matt master mask production, polyester base film coating, seamless die pressing, hot transfer printing of a polypropylene film by a polyester laser film, aluminum plating, back glue coating and the like. According to the invention, the aluminum foil imitating effect of the special film for the aluminum-foil-imitating aluminum-plated paper is improved by the holographic plate making and seamless transfer printing and die pressing techniques; after the film is compounded into finished product paper, the equivalent effect of the aluminum foil composite paper can be achieved; the matt laser printed by the polypropylene film is permanent laser; and after the laser film is transferred, the die pressing working procedure is not needed, and the laser film can be used as a matt film to be repeatedly used more than 15 times after direct aluminum plating, thus the production cost is lowered.
Description
Technical field
The present invention relates to the preparation of wrapping paper, specifically the production technology of BOPP dumb light laser film for a kind of imitative aluminium foil aluminium paper.
Background technology
Aluminium-foil paper is by the pure aluminum foil of 0.06-0.07mm and 30-350g/m
2body paper carries out the compound wrapping paper that wet type or dry type are composited, and is mainly used in tobacco and wine, cosmetic package.
Vacuum aluminium paper can be divided into two kinds of direct method (paper is aluminium-plated) and transfer methods (face is aluminium-plated) by production technology.Direct method is paper to be directly placed in to the aluminium-plated machine of vacuum carry out aluminium-plated method, and it is aluminium-plated that this method only limits to thin paper.Transfer method is taking PET, BOPP film as transfer substrate, through coating colouring, aluminium-plated, compound, the PROCESS FOR TREATMENT such as peel off, the aluminium-plated molecular layer that makes to have metallic luster is transferred to the method on Paper or cardboard surface by adhesive action, this method can be produced 40～450 grams of above Paper or cardboards.Aluminium paper with aluminium amount only aluminium foil 1/200, degradability is good, can save production cost, and can not cause environmental pollution simultaneously, belongs to environment-friendly packaging material, is the alternative AKU package material of aluminum foil composite paper plate.
With the imitative aluminium foil of aluminium paper, generally adopt dumb light transfer coatings rubbing method at present, the site of flatting silica is obvious, compared with aluminium foil, range estimation metal-like is poor, and low luster coating coating process yield rate is low, has the imitative aluminium foil dumb light effects in impact surface such as flatting silica coating wire drawing, hangover, shadow.
Summary of the invention
