Problems solved by technology

However, the molding method of this single-plate roller has the following defects: (1) plate-attaching is more troublesome, and the service life is not long. The normal production of a nickel plate is 30,000-50,000 meters, so that it is time-consuming and expensive to produce nickel plate
(2) The existing technology adopts the holographic mother film structure to transfer the laser through the film transfer method; although the laser holographic nickel plate has been omitted by the film transfer method, and the life is greatly prolonged, the general life of the film transfer mother film is 10- Between 150,000 meters, but the production efficiency is low

Abstract

The invention relates to the technical field of laser holographic films, in particular to a technology for producing a casting polypropylene (CPP) film laser holographic film. According to the technology for producing the CPP film laser holographic film, a single-plate-roller film transferring production technology is adopted, the processes of plate pasting and plate mounting in the prior art areavoided, the problem of a short lifespan of a nickel plate caused by the plate pasting is further avoided, thus effective production can be further realized, and the cost of the nickel plate is saved;in addition, since a single plate roller is heated to complete film transferring by a heating mode, the nickel plate high temperature laser holographic embossing in the prior art is avoided, the filmtransferring of the technology does not need the temperature to be too high, and the energy consumption is saved; and in addition, according to the mode of the film transferring, chemical compositions are greatly reduced. Therefore, technology for producing the CPP film laser holographic film has the advantages of being capable of easily saving the nickel plate, beneficial to improving productionefficiency, and environmentally friendly.

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 the laser through t...
