Problems solved by technology

The most critical technology for making laser anti-counterfeiting film is the embossing operation. Embossing must ensure that the indoor air is clean. This operation requires a high temperature of 160-180 degrees, 43KG / square meter operating conditions, and continuous heating of the heating roller. Oil heating consumes a lot of electricity
Moreover, changes in high-pressure temperature and pressure cause deformation of the film, and the production speed is only 45-60 m / s, which cannot be too fast, otherwise the laser anti-counterfeiting information pattern cannot be completely transferred, which will have a greater impact on subsequent operations
Moreover, the current production process is mostly single-plate. Compared with seamless production, single-plate is low in efficiency, high in cost, and consumes more resources.
At present, the seamless film process is mostly secondary embossing. First, a layer of embossing layer with interval lines is laminated on the base film layer, and a second embossing layer with interval lines is laminated on the embossing layer. The printing layer, the lines of the two embossings are partially superimposed, so that the laser film can be seamlessly compounded, and the product grade can be improved without any laser shadow, but the second embossing consumes more resources

Abstract

The invention discloses a laser holographic anti-counterfeiting UV plate-seam-free film processing process including base film processing, film pressing, master plate manufacturing, pre-coated film manufacturing, pre-coated film drying, secondary film pressing and demolding winding. Due to the adoption of the technical scheme, process steps are reduced, and a two-time film pressing process of UV plate-seam-free films in the current industry can be replaced. In the process, a plate-seam-free film is used as the master plate, one-time film pressing transferring is conducted, and the master platecan be repeatedly used. The energy consumption is reduced, and efficiency is improved; usage of heating oil, usage of nickel plates and the like are reduced, and plate-seam-free master plate film repeated utilization is achieved; the production cost is reduced, and resources are saved; the environment friendliness is improved, and compared with the adoption of other paint such as light silver transfer paint and release film pressing paint, the adoption of UV varnish coating has the advantages that a UV coating film is high in temperature resistance, high in friction resistance and weak in volatility and meets the requirement of environment friendliness; and the manufactured UV plate-seam-free films are resistant to high temperatures and friction and are wide in application.
