Abstract
An adhesive for use in cigarette manufacturing which is a natural based starch material having excellent flow or fluidity characteristics and viscosity stability and comprising a mixture of crosslinked starch and a fluidity or converted starch, particularly an acid converted starch, the starches having an amylopectin content of at least 70% by weight and prepared by cooking at high temperature and pressure.
Claims19
An adhesive composition for use in cigarette manufacturing comprising a starch composition which is a mixture of a crosslinked starch with a fluidity or converted starch, said starches having an amylopectin content of at least 70% by weight, and said starch composition prepared by cooking said starch mixture at a temperature of at least 100.degree. C. and pressure of at least 30 psi, the adhesive composition having a solids content of about 10 to 60% and a Brookfield viscosity of about 500 to 20,000 cps at 22.5.degree. C.
In a method of manufacturing cigarettes the improvement comprising the use of an adhesive composition comprising a starch composition which is a mixture of a crosslinked starch with a fluidity or converted starch, said starches having an amylopectin content of at least 70% by weight, and said starch composition prepared by cooking said starch mixture at a temperature of at least 100.degree. C. and pressure of at least 30 psi, the adhesive composition having a solids content of about 10 to 60% and a Brookfield viscosity of about 500 to 20,000 cps at 22.5.degree. C. as the adhesive.
In a method of manufacturing cigarettes the improvement comprising the use of an adhesive composition comprising a starch composition which is a mixture of a crosslinked starch with a fluidity starch which is an acid converted starch having a fluidity of from about 40 to 90 WF, said starches having an amylopectin content of at lest 70% by weight, and said starch composition prepared by jet cooking said starch mixture at a temperature of from about 120 to 220.degree. C. and a pressure of from about 120 to 220 psi, the adhesive composition having a solids content of about 10 to 60% and a Brookfield viscosity of about 500 to 20,000 cps at 22.5.degree. C. as the adhesive.
