Sizing adds value to the paper quality by enhancing its properties. Sizing paper with starch can increase both the surface strength of the paper, as well as the bulk strength. Sizing or pigmenting can also be applied with PVA or silicone which transforms the base paper into release paper. Additionally, sizing can be used to densify and seal the paper surface, thus reducing the absorption, for instance, from the coating process.
