SPOKANE, WA, Jan. 31, 2012 (Press Release) -Clearwater Paper Corporation, a leading manufacturer of bleached paperboard products, today announced it has signed a license agreement to extrude EarthCoating^TMresins from Smart Planet Technologies^TMfor use in the full line of Candesce® paperboard products.

The EarthCoating^TMresins are innovative, high performance, mineral-based coatings, which contain less plastic than traditional low-density polyethylene coatings while providing enhanced moisture barrier properties and equal barrier properties to oil, grease and fatty acids. EarthCoating^TMis FDA-compliant for direct food contact.

"Our agreement with Smart Planet Technologies will enable Clearwater Paper to offer our customers unique extrusion coatings options that reduce the amount of polyethylene used while maintaining or enhancing package performance," said Richard Dreshfield, Director of Marketing & 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."

"By adding EarthCoating^TMto their Candesce product line, Clearwater Paper brings a new paperboard solution to converters and their customers looking to reduce the amount of polyethylene in their packaging while enhancing moisture-vapor transmission rates," said Chris Tilton, chief technology officer of Smart Planet Technologies^TM, Inc.
