Clearwater Paper Corp., a manufacturer of bleached paperboard products, has signed a license agreement to extrude EarthCoating™ resins from Smart Planet Technologies™ for use in the full line of Candesce® premium SBS paperboard products.

EarthCoating resins are high-performance, mineral-based coatings that contain less plastic than traditional LDPE coatings, while providing enhanced moisture-barrier properties and equal barrier properties to oil, grease, and fatty acids. EarthCoating is FDA-compliant for direct food contact.

“Our agreement with Smart Planet Technologies will enable Clearwater Paper to offer our customers unique extrusion coating options that reduce the amount of polyethylene used while maintaining or enhancing package performance,” says Richard Dreshfield, director of marketing and customer service for Clearwater Paper’s Pulp and Paperboard Division. “The beauty of the new resin is that it converts like low density poly-coated material, meaning that it can be printed, die-cut, folded, and glued using existing equipment.”
