Penford Products introduces PenStrength for recycled paperboard applications

In Iowa, Penford Products 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. This cationic polymer is derived from natural and renewable resources, and is currently being used by major producers of core and tube, recycled linerboard and medium and boxboard.
