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.
