Coater equipment is divided into in-machine type and out-of-machine type in the process of paper machine. It is divided into single layer coating and double layer coating according to the number of coating. In-machine coating is equipped with a coater on the paper machine to make papermaking and coating continuous. Double-coated paper has better printability than single-layer coated paper, and can improve the quality of coated paper.

There are mainly three types of coater used for coating operations: roll coater, air doctor coater and blade coater.Main production: kraft cardboard, white cardboard, art paper, matte paper, two-side offset paper, carbonless copy paper, thermal paper etc.
