Abstract
An adhesive for use in cigarette manufacturing which is a natural based liquid starch phosphate material having good flow or fluidity characteristics and viscosity stability and comprises a phosphorylated starch material made from a fluidity or converted starch having a high amylopectin content, the final starch phosphate composition prepared by steam injection cooking the phosphorylated starch at high temperature and pressure.
Claims12
In the method of manufacturing cigarettes wherein a cigarette rod is formed by wrapping tobacco in a paper tube which is bonded along one longitudinal edge with a side seam adhesive and an optional filter is formed having several adhesive bonds including a center-line adhesive bond where the filter material is attached to plug wrap paper, an overlap adhesive bond where the paper is wrapped around the filter plug and attached to itself in an overlapping manner and a tipping adhesive bond where the filter plug is attached to the cigarette rod by wrapping another paper around the plug and overlapping it with an aligned cigarette rod, the improvement comprising applying as the adhesive in at least one of the side seam, center-line, overlap and tipping bonds, a liquid starch phosphate adhesive composition consisting essentially of a phosphorylated starch material having from about 0.38 to 1.0% of bound phosphate, the starting starch material being a fluidity or converted cereal starch having an amylopectin content of about 90% or more by weight, the final starch phosphate composition prepared by steam injection cooking the phosphorylated starch at a high temperature and pressure, the adhesive having a solids content of greater than 25%.
