Abstract:
A corrugating adhesive composition of the carrier or carrier-no-carrier type which in an aqueous emulsion comprises water; from about 5 to about 35 parts solubilized plant fiber per 100 parts of adhesive and, optionally, an added carbohydrate component comprised of unmodified starch and/or modified starch and/or dextrin in an amount from about 0.1 to about 99% by weight based on total added carbohydrate and solubilized fiber; a boron containing compound in an amount of from about 0.2 to about 1 part per 100 parts of adhesive; and sufficient caustic to attain a pH from about 8 to about 14 wherein the adhesive has a carrier phase and fiber has been solubilized in situ in preparing the carrier phase and residual insoluble particles having a geometric mean size of less than about 0.00005 inch and a median size of less than about 0.00005 inch are present in the composition.
