A method for preparing a binder composition containing water, plant fibers and mineral fillers, wherein the method comprises: preparing a suspension of plant fibers and mineral fillers in water, the weight ratio between the plant fibers and the mineral fillers being comprised between 99/1 and 2/98, refining this suspension, and obtaining a binder composition wherein the refined fibers have a mean size of between 10 and 700 μm, and wherein the refined fibers, at least partially, embed the refined mineral fillers,
wherein refining is carried out in the absence of any grinding medium made of ceramic or metal.

The present application provides a dispersion dispersed satisfactorily cellulose nanofibers, powdery cellulose nanofibers obtained by pulverizing thereof, a resin composition obtained by blending thereof and a molding raw material for a 3D printer by using thereof. It is possible to obtain a composition uniformly finely dispersed the cellulose nanofibers by treating a mixture containing unmodified cellulose nanofibers and a dispersant using a high speed agitating Medialess disperser, and followed by pulverizing the composition to blend with a resin and a rubber component. Also, a resin composition improved in mechanical properties and heat resistance, obtained by blending the powdery cellulose nanofibers above with a thermoplastic resin or a thermosetting resin, is useful as a molding material for a 3D printer.

The present invention relates to coated paper or paperboard comprising: a paper or paperboard substrate, and a solid closed cell foam coating layer disposed on a surface of said a paper or paperboard substrate, wherein said solid closed cell foam coating layer comprises a nanocellulose, and a foaming agent. The invention further relates to a food container, preferably a cup, comprising such coated paper or paperboard.
