The future of paper products is predicted to lie in intelligent and functional paper properties. These properties are achieved by using coating materials, which are usually very expensive, but the amount needed is also very small. This requires a new type of coating method. In this study we introduce foam coating, a technology widely used in the textile and non-woven industry. The technology offers a unique opportunity to apply coating on the web surface thinly enough to be economically viable. Our pilot scale studies show that a thin coating layer of nanomaterial. with a thickness of 1 μm or less and coat weight from 0.3 to 2 g/m2, is enough to change paper surface properties and enable the functionalization of the paper surface. This paper shows the applicability of the foam coating technology in unmodified nanofibrillated cellulose (NFC) applications.
