Abstract

The invention relates to the technical field of laser holographic film, in particular to a production process of a CPP film laser holographic film. The production process of the CPP film laser holographic film, due to the use of the production process of single-plate roll film transfer film, avoids the process of plate-mounting and frame-plate in the prior art, thereby avoiding the problem of short life of the nickel plate caused by plate-mounting, and then Effective production can be achieved, saving the cost of the nickel plate; in addition, because the heating single-plate roller completes the film transfer by heating, avoiding the high-temperature laser holographic embossing of the nickel plate in the prior art, the film transfer of the present application does not The required temperature is too high, which saves energy consumption; in addition, the method of membrane transfer in this application greatly reduces the chemical composition. Therefore, the production process of the CPP film laser holographic film has the advantages of easy saving of nickel plates, improvement of production efficiency and environmental protection.

Description

technical field

[0001] The invention relates to the technical field of laser holographic films, in particular to a production process of CPP film laser holographic films. Background technique

[0002] In the prior art, the production methods of laser holographic PET film and OPP film are as attached figure 1 As shown, there is a single version roller, the single version roller is pasted with a holographic nickel plate, and the single version roller is filled with hot and cold oil, and the holographic film to be lasered is sequentially laser molded by the single version roller. However, the molding method of this single-version roller has the following defects: (1) plate-attaching is relatively troublesome, and its lifespan is not long. A piece of nickel plate normally produces 30,000-50,000 meters, so that it is time-consuming and wastes nickel plate for mass production. (2) The existing technology adopts the holographic mother film structure to transfer laser through the f...
