Surface Sizing of Paper
Servall's Sizer products offer various application methods for all paper machine sizes grades - with film and pond application. All sizers have a robust and optimised construction combined with high functionality and
quality with a low cost of ownership.
In surface sizing or size application, Surface Sizing Starch, or other types of size or pigmented size, is applied to the paper sheet surface to improve its strength, surface properties or water resistance. Sizing is often used to modify surface properties before coating.
Surface Sizing in Paper Industry is used throughout manufacture to reduce the paper's tendency once dry to soak up liquid, with the goal of permitting inks and paints to stay on the surface of the paper and to dry there, instead of be absorbed into the paper.
