 CMC is the widely used additive in paper industry because it mainly has membrane and oil-resistance capability as water soluble superpolymer..

CMC is used as paper gluing agent to provide paper with high compactability,fine anti-ink osmosis and high was gathering capability.

CMC can help control colour paste flowing for paper and during paper variegation.

Increase paper strength and flod-resistance and improve stickiness in paper cellulose.
