Manufacturing of High Quality Coated Paper using Environmental Friendly Plasma Technology(II)

In the previous study, the possibility of modifying the surface properties of base paper with plasma treatment was evaluated. It was shown that only the hydrophilic properties of the base paper surface was increased while there was no changes in physical and optical properties. Only the surface of the plasma treated side was modified. In this study, the effect of plasma treatment on binder migration was elucidated. The base paper was plasma treated with various voltage and then the plasma treated base papers were coated with varying coated weight. The surface strength of the coated paper (dry and wet pick) was increased with plasma treatment, which implies that the plasma treatment of base paper can inhibit the binder migration.
