Cooked flour-containing corrugated paperboard adhesives and use thereof

Abstract

Abstract An improved, viscosity-stable cooked flour-containing Stein-Hall type corrugated paperboard adhesive having an uncooked slurry portion and a cooked paste portion as a carrier therefor wherein the slurry portion comprises an amount sufficient to provide the requisite tack to the mixture of a smooth, stable homogeneous colloidal co-solution, substantially free of undissolved fiber, of both the protein and starch fractions of a proteinaceous grain flour, the protein fraction being substantially non-degraded and the starch fraction being essentially a chemically unmodified starch or as molecular weight reduced starch, which is chemically unmodified, the resultant adhesive being viscosity-stable with substantially higher tack than corresponding normally gellable conventional adhesives of the same flour content.
