Paper surface sizing
A surface sizing chemical is applied to the surface of the paper or board to change the characteristics of the sheet surface to meet conversion and end-use requirements. Surface sizes provide excellent control over hydrophobicity properties, including water hold-out and ink resistance, as well as ensuring good coating conditions when the paper or board is coated or laminated.
Surface sizing can have an impact on many other properties including toner adhesion, printability, dusting, smoothness, permeability and ketone migration.
With surface sizing playing such a significant role in the final product, it is vital that the papermaker works with a supplier that has the capability and flexibility to meet the ever-changing demands in the market.
