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.
This cationic polymer, derived from natural and renewable resources, is currently being used by major producers of core and tube, recycled linerboard and medium and boxboard.
Benefits and Features
- Achieves higher ring crush and STFI results so as to enable the production of premium grades
- Decreases cost by reducing basis weight without loss of strength and/or providing an ability to use less expensive fiber sources
- Increases production and process efficiency for more saleable tons
- Conserves steam and electrical resources by reducing refining and improving drainage
- Optimizes wet end chemistry to reduce additive costs
“PenStrength is an example of Penford’s dedication to innovating sustainable technologies and applications. We are excited to introduce PenStrength to the recycled paperboard industry as a viable alternative to synthetics,” said Dan Walter, vice president of BioProducts at Penford. “We are committed to keeping expenses down, while offering environmentally-friendly, high performance products. At Penford we believe that quality does not have to be compromised in order to generate superior green products.”
