Abstract: Environmentally friendly biopolymer adhesives are described, wherein the adhesives comprise biopolymer particles, more preferably starch microparticles, and most preferably starch nanoparticles, and their aqueous dispersions. Applications for the biopolymer particle adhesives are described, that are environmentally friendly alternatives to petroleum based synthetic adhesives. The biopolymer particle adhesives provide are biodegradable as well as repulpable, and thus provide bio-based recycling-friendly alternatives to synthetic adhesives derived from petroleum resources.

Abstract: The invention concerns a process for producing corrugated board, wherein a biopolymer latex adhesive is used as the corrugating adhesive. The biopolymer latex adhesive can be obtained by extruding a plasticized biopolymer, especially starch, in the presence of a crosslinking agent such as glyoxal. The preparation of the latex adhesive and its application in corrugating operation do not require a gelatinization step, nor the use of caustic soda or borax.
