ABSTRACT:
This invention provides coated tobacco product having a hydrophobic coating on at least one surface thereof, the coating comprising a cellulose propionate having an acetyl content of less than about 6% by weight, a hydroxyl content of at least 1.5% by weight, and a content of acyl groups of more than about 3 carbon atoms of less than about 10% by weight. The coating preferably comprises a mixture of the aforesaid cellulose propionate with a glyceride having the general formula: ##STR1## wherein preferably one of the R groups is a group selected from the group consisting of acetyl and propionyl, at least another R residue group represents an acyl containing at least about 12 carbon atoms, any remaining R group is hydrogen. The coating composition is applied, e.g. to a reconstituted tobacco product, as a clear solution in a volatile solvent. The volatile solvents which are suitable include alcohol-water mixtures, esters, and anhydrous alcohol-ester mixtures. If desired, a cross-linking agent may be present to increase the water-resistance of the resulting hydrophobic film.
