CEDAR RAPIDS, Iowa, Aug. 6, 2013 /PRNewswire/ -- Penford Products, a leading global supplier of specialty bioproducts, recently introduced PenStrength, a high-performance cationic polymer. PenStrength enhances the binding of pulp fibers to make recycled paperboard stronger, allowing manufacturers to produce premium grade paperboard while reducing manufacturing costs. By using PenStrength, paperboard producers can reduce production costs by up to $10 – 40 per ton. Penford has filed a patent application covering this novel product.
