Printing process for patterned wrapper paper

A process for making patterned wrapper paper applies an aqueous solution of oxidized starch material to a base web (10) of paper. The aqueous starch solution has a surface tension of at least about 65dynes/centimeter, a pH in the range of about 6 to about 6.5, a room temperature viscosity no greater...

More Information
Summary:A process for making patterned wrapper paper applies an aqueous solution of oxidized starch material to a base web (10) of paper. The aqueous starch solution has a surface tension of at least about 65dynes/centimeter, a pH in the range of about 6 to about 6.5, a room temperature viscosity no greater than about 50 centipoises, and is prepared from particles sized in the range of about 4 to about 40 microns when dry and about 90% of which are sized in the range of about 10 to about 100 microns when wet. The starch particles are capable of forming a solution with about 20% to about 24% oxidizedstarch content. Any suitable printing technique can be used to apply the aqueous solution. The pattern of the wrapper may comprise bands (34), stripes (36), two-dimensional arrays, and the like. Moreover, the pattern can be applied in one or more layers (40, 42). The invention includes a cigarette having the wrapper.
