1. Roller coating

The roller coating device is used to transfer the varnish to the surface of the carton. The coating amount and pressure of the coating unit are controlled by the printing machine control center. When working in the form of three roller reverse operation, the coating roller and the bucket roller operate in reverse to obtain the coating film layer with good brightness. At the same time, when using the high viscosity coating solution, it is not necessary to increase the pressure between the rollers to achieve thin and uniform coating. The roller coating device has the advantages of short transmission route, less contact points, less drying of the coating solution, uniform transmission of the coating solution, simple and convenient operation, etc.
