Paper Coating Machine

A paper Coater applies coating evenly onto the paper base surface using rollers, forming a functional layer after drying. It is used to enhance the printability, smoothness, or barrier properties of paper and is commonly employed in the production of coated paper and packaging paper.
Selection
Select the coating weight range based on the paper grammage, match the drying capacity with the production speed, determine the roller material according to the coating viscosity, choose the coating method (blade or air knife) based on the product's intended use, and reserve 10-15% power margin to handle peak loads.
