摘要

Process for surface treatment, preferably surface sizing, of a continuous material web, preferably paper or cardboard, comprises applying a starch containing surface treatment agent as a pre-dosed film on at least an assigned surface of the material web using a film applying device, where the starch is a thermally-chemically modified starch, and the solid content of the surface treatment agent is reduced, when compared to native starch viscosity.
