Size Press

Equipment Category: Size Presses

Press-Section-Rolls

The purpose of a size press on a paper machine is to apply a solution of starch or other material onto the surface of the dry paper, after which the paper is dried again. Usually the main role of the applied material is to increase the surface strength of the paper. Other benefits can include reduced dusting tendency, increased stiffness, and reduced air-permeability. Papermakers also can add copolymers such as styrenemaleic anhydride (SMA), styrene acrylates (SA), or urethane copolymers to size-press starch if they want to achieve increased resistance to liquids or higher levels of surface strength.
