Chitosan is used in the manufacturing of paper because chitosan molecules greatly resemble those of cellulose, the main constituent of plant walls. It replaces amine substitutes such as guar gum and polysynthetic polysaccharides.
It also saves chemical additives and increases output.
The paper produced with chitosan has a smoother surface and is more resistant to moisture.Chitosan is of great value in the production of toilet paper and for wrapping paper and cardboard.
