The invention discloses a chitosan-contained waterborne coating for cigarette wrapping paper. The chitosan-contained waterborne coating is prepared from the following components in parts by weight: 20-30 parts of chitosan powder, 12-18 parts of CMC (Carboxymethyl Cellulose), 16-24 parts of starch and 180-220 parts of water as solvent, wherein the starch is formed by mixing cassava starch and guar gum in a weight proportion of 10 to (3-30). The invention has the advantages that the chitosan-contained waterborne coating for the the cigarette wrapping paper can be favorably adhered to the wrapping paper, can effectively ensure the absorption function of the chitosan to reduce harmful substances in cigarette smoke, has simple production process and low cost, does not generate residual volatile organic solvents after coating due to the adoption of the water as the solvent, saves energy and is safe, pollution-free and safer to smoke, and the CMC can enhance the strength of the paper and improve the yield of the wrapping paper.
