Abstract
The adhesive composition is a cooked blend of a waxy starch white dextrin and a waxy starch hydrolysate having a DE of around 20. The adhesive composition can be made to have a solids level of up to 70% and the ratio of dextrin to hydrolysate in the adhesive is 1:1 to 1:2.
Claims20
An adhesive composition for use as a cigarette seam adhesive comprising a cooked aqueous blend of
- (a) about 10 to about 45 parts by weight of a high amylopectin starch dextrin, wherein said high amylopectin starch dextrin has at least about 70% by weight amylopectin and said high amylopectin starch dextrin has a cold funnel viscosity of about 20 to about 120 mls when measured at about 42% solids dry basis,
- (b) about 15 to about 60 parts by weight of a high amylopectin starch hydrolysate, wherein said high amylopectin starch hydrolysate has at least about 70% by weight amylopectin and said high amylopectin starch hydrolysate has a Dextrose Equivalent of about 10 to about 30, and
- (c) about 20 to about 60 parts by weight water,
- (d) said aqueous blend having a Brookfield viscosity of about 500 to about 15,000 cps when measured at a solids content of about 60% by weight, about 20 rpm, and a temperature of about 25.degree. C.
An adhesive composition for use as a cigarette seam adhesive comprising a cooked aqueous blend of about 10 to about 45 parts by weight of a dextrin, about 15 to about 60 parts by weight of a starch hydrolysate and about 20 to about 60 parts by weight water, said dextrin being a waxy maize white dextrin having a cold funnel viscosity of about 20 to about 120 mls when measured at about 42% solids dry basis, said starch hydrolysate being a waxy maize starch hydrolysate having a Dextrose Equivalent of about 10 to about 30, and said blend having a Brookfield viscosity of about 500 to about 15,000 cps when measured at 60% solids, about 20 rpm, and a temperature of about 25.degree. C.
In a method for manufacturing a cigarette with a paper outer layer, the improvement comprising using as an adhesive for the longitudinal seam of said paper a cooled aqueous blend comprising
- (a) about 10 to about 45 parts by weight of a high amylopectin starch dextrin, wherein said high amylopectin starch dextrin has at least about 70% by weight amylopectin and said high amylopectin starch dextrin has a cold funnel viscosity of about 20 to about 120 mls when measured at about 42% solids dry basis,
- (b) about 15 to about 60 parts by weight of a high amylopectin starch hydrolysate, wherein said high amylopectin starch hydrolysate has at least about 70% by weight amylopectin and said high amylopectin starch hydrolysate has a Dextrose Equivalent of about 10 to about 30, and
- (c) about 20 to about 60 parts by weight water, and
- (d) said aqueous blend having a Brookfield viscosity of about 500 to about 15,000 cps when measured at a solids content of about 60% by weight, about 20 rpm, and a temperature of about 25.degree. C.
