Sodium carboxymethyl cellulose (Na-CMC) binds tobacco powder, additives, and other components together during the rolling moulding of reconstituted tobacco. Due to its insufficient bonding, the product has low tensile strength and a high shredding rate. The standard preparation of Na-CMC solutions suffers from long preparation times and low adhesion. This research used glycerol as a co-solvent, quickly dissolved Na-CMC solutions and increased adhesive solution adherence. When the glycerol/Na-CMC ratio was more significant than or equal to 11:1, the adhesive solution’s adhesion was enhanced by more than 100% compared to conventional Na-CMC solutions at equivalent concentrations. When the highly adhesive Na-CMC solution was applied to reconstituted tobacco, the tension index increased by 192.59%, and the elongation at break increased by 147.14%. The shredding rate decreased by 61.83%. This method should help various Na-CMC industries obtain excellent adhesion at lower adhesive solution concentrations.
