  • Low moisture process for extracting hemicellulose
    Publication number: 20040147738
    Abstract: The invention concerns a process for extracting hemicellulose from fiber, such as corn fiber. The process comprises agitating at least fiber, caustic and optional added water at a moisture content from about 10% to about 60% at high speeds in a highly fluidized state. The process substantially instantaneously extracts the hemicellulose from the fiber. Heat may be applied in the process to extract and dry the hemicellulose substantially simultaneously.

  • Corrugating adhesives for bonding coated papers and methods for bonding coated papers
    Publication number: 20040102546
    Abstract: A corrugating adhesive that improves the bonding of coated papers, including latex coated medium and linerboards. The corrugating adhesive may comprise a hydrocolloid portion of the adhesive that improves tack and bonding and buffers and absorbs caustic in the adhesive allowing higher caustic in the adhesive formula without premature gelling of the secondary starch portion. Also, methods for making waterproof or water resistant corrugated board from corrugated media and paper liner.

  • Preblended carrier starches for corrugating adhesives
    Patent number: 6228158
    Abstract: A dry preblended carrier starch for corrugating adhesive compositions comprising modified starch and a dry alkali, the modified starch being preferably oxidized starch and the dry alkali being sodium metasilicate or trisodium phosphate. The dry preblended carrier starch for corrugating adhesives has improved viscosity stability over time and temperature fluctuations, eliminates the need for added caustic at end use or at the corrugator and does not require additional silicate compounds in the corrugating adhesive.

  • Starch replacement composition for corrugating adhesives and the adhesives prepared therewith
    Patent number: 5972091
    Abstract: A dry blend pre-mixture composition for use in making corrugating adhesives is comprised of starch and from about 5% to about 20% of ground plant germ. The starch and germ can be derived from various plant sources and in a preferred embodiment the starch is corn starch and the germ is ground corn germ, also known as spent flake. The corrugating adhesives can be prepared by using the pre-mixture as a replacement for starch in a process for making a carrier, no-carrier or carrier-no-carrier adhesive.
