Problems solved by technology

However, the current laser hot stamping film has poor adhesion to metal, and the solvent resistance and physical damage resistance of the coating itself are relatively poor, so that the existing laser hot stamping film cannot be widely used on aluminum substrates.
In particular, for wine packaging products that require anti-counterfeiting labels, aluminum is mainly used to prepare wine caps. These wine caps need to be exposed to alcohol for a long time or are of

Abstract

The invention relates to the technical field of laser gliding membranes, in particular to a laser gilding membrane for an aluminum substrate and a production process and an application thereof. The laser gliding membrane is composed of a PET membrane layer, a release layer, a wear-resistant resin layer, a three-dimensional picture layer, an aluminizing layer and a glue layer which are laminated, wherein the release layer, the wear-resistant resin layer and the glue layer are separately prepared from raw materials in percentage by weight, so that the laser gilding membrane for the aluminum substrate can be better attached to the aluminum substrate and has the advantages of being good in adhesiveness, friction resistant, solvent resistant and good in laser effect. The production process of the laser gilding membrane for the aluminum substrate comprises the following steps: preparing a coating of the release layer, the wear-resistant resin layer and the glue layer; and then carrying out coating, coining a pattern, carrying out aluminizing and coating the glue layer. The membrane has the advantage of simple production process. The laser gilding membrane can be applied to stamping anti-fake gliding trademarks of aluminum liquor lids, so that the anti-fake technology of the aluminum liquor lid is carried forward.

Description

technical field [0001] The invention relates to the technical field of laser bronzing film, in particular to a laser bronzing film for aluminum substrates and its production process and application. Background technique [0002] Hot stamping printing is to use the template on the hot stamping machine with the help of certain pressure and temperature, and then press the printed matter and the hot stamping film in a short time, so that the hot stamping film or pigment foil is transferred to the printed matter according to the pattern of the hot stamping template Surface processing technology. At present, the main substrates of laser hot stamping film are paper, ABS, PS, NYLON, PVC, PP, PE and glass. [0003] However, with the development of commodities, aluminum substrates are also widely used in product packaging. However, the current laser hot stamping film has poor adhesion to metal, and the solvent resistance and physical damage resistance of the coating itself are relat...
