Problems solved by technology

[0003] However, the laser nickel plate needs to use nickel ingots to form the laser plate by electroforming, and a laser nickel plate can only imprint 30,000 to 50,000 meters of laser film and needs to be replaced, which limits the service life of the laser film; In addition, When the laser nickel plate is used in an application environment where the coating material is dirty or the machine environment is poor, the laser nickel plate will also be damaged, which will also shorten the service life of the laser plate
In addition, the nickel ingot used in the laser nickel plate is a precious metal, which undoubtedly increases the production cost

Abstract

The invention relates to the technical field of laser transfer films, in particular to a laser mother film for a film pressure transfer film as well as a preparation method and an application method of the laser mother film. The transfer film comprises a PET film, a coating, a laser film pressure layer and an aluminum plating layer which are sequentially laminated, wherein the coating is preparedfrom 30%-50% of acrylic resin, 2%-5% of cellulose acetate, 20%-40% of n-propyl acetate, 1%-5% of cellulose acetate and 15%-25% of a leveling agent. The laser mother film can press a laser pattern on the transfer film, has the advantage of saving production cost, the preparation method has the advantage of being easy to operate and the application method is helpful to reduce energy consumption.

Description

technical field [0001] The invention relates to the technical field of laser transfer film, in particular to a laser mother film used for film pressure transfer film and its preparation method and application method. Background technique [0002] The existing laser transfer film production process is to use a laser nickel plate to emboss the coated transfer film, and the laser lines on the laser nickel plate are printed on the coating layer of the transfer film to form a laser effect. [0003] However, the laser nickel plate needs to use nickel ingots to form the laser plate by electroforming, and a laser nickel plate can only imprint 30,000 to 50,000 meters of laser film and needs to be replaced, which limits the service life of the laser film; In addition, When the laser nickel plate is used in an application environment where the coating material is dirty or the machine environment is poor, the laser nickel plate will also be damaged, which will also shorten the service l...
