20120138249 | Method for improving paper and board's resistance to the penetration of liquids - This invention brings a new aspect in papermaking by spraying hydrophobic chemical directly onto the paper surface in the dryer section of the paper machine, as a two-step process where high solids starch is sprayed on the paper to seal the sheet's surface and thereafter the hydrophobic chemical is sprayed on the paper surface.
