Abstract:To improve the physical properties of tobacco sheet， the effect of adding nano-cellulose to the coatings on the properties of tobacco sheet during the coating process of papermaking tobacco sheet was discussed， and the kinds and dosage of nano-cellulose were optimized.The results showed that the effect of CNC was the best among three kinds of nano cellulose. It was more appropriate to add 0.1% CNC （based on the dried coating）. The addition of CNC had no negative effect upon coatings. The tensile index of the tobacco sheet increased from 10.1 N·m/g （the control group） to 13.3 N·m/g. The increment reached 32.6%. And surface strength increased from 1.35m/s （the control group） to 1.74m/s. The increment reached 28.9%．
