Abstract

The invention relates to laser direct plating paper and a preparation method thereof. The preparation method comprises the following steps: (1) coating: coating a lightweight coated paper with the specification of 50-70g / m<2> by using a laser information layer, and drying after the coating is over, wherein the laser information layer comprises the following compositions in percentage by weight: 65.0-68.0% of laser-based precoated resin, 15.0-20.0% of ethanol, 8.0-12.0% of ethyl ester, and 8.0-12.0% of butanone; (2) laser mould pressing: carrying out mould pressing on the lightweight coated paper coated with the laser information layer through a mould pressing machine, wherein a plurality of laser patterns are carved on a roller of the mould pressing machine, and the laser patterns are imprinted onto the lightweight coated paper through mould pressing; (3) aluminum plating; (4) coloring and regaining moisture, to obtain the laser direct plating paper finished product. The laser direct plating paper finished product is wear-resistant and scratch-resistant, easy to print, anti-counterfeiting and the like, and can be widely applied to the fields of cigarette packets, beer labels, gift packages, decorations and the like.

Description

technical field [0001] The invention belongs to the technical field of wrapping paper, and in particular relates to a laser direct-coated paper and a preparation method thereof. Background technique [0002] Laser aluminized paper is a kind of flexible packaging printing material with laser anti-counterfeiting effect and metal "aluminum luster" and good barrier properties. It has been widely used in high-end cigarette lining paper, beer label paper, health care products, medicine, cosmetics and other products. Inner packaging and trademark labels. In order to make the paper obtain laser and metallic luster effects, the surface of the paper must be coated to meet the requirements of laser molding and vacuum aluminum plating. The film is compounded on the paper. The laser paper produced by this method has the disadvantages of being difficult to degrade and not environmentally friendly. The second is to transfer the laser transfer film to the paper by transferring the laser. T...
