PRINTING PROCESS FOR PATTERNED WRAPPER PAPER

摘要

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 65 DYNES/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% OXIDIZED STARCH 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 (38), AND THE LIKE. MOREOVER, THE PATTERN CAN BE APPLIED IN ONE OR MORE LAYERS. THE INVENTION INCLUDES A CIGARETTE HAVING THE WRAPPER.
