Naturally-Derived Biopolymers Have Equivalent Performance to Protein

with Added Environmental and Cost Benefits


Cedar Rapids, Iowa (June 18, 2013) – Penford Products, a division of Penford Corporation (NASDAQ: PENX), today announced Pen-cote PR, a new biopolymer product line made to replace protein in paper coatings.  Pen-cote PR, available in both dry and liquid form, was developed using Penford’s proprietary PenFlex™ technology, which produces high performance, cost effective biomaterials.  Pen-cote PR biopolymers are VOC free, environmentally sustainable products that are easy to use, improve runnability and reduce operating costs in paper coating processes that have traditionally relied on protein.


Runnability Benefits

  • Higher water retention for improved surface appearance
  • Enhanced binding strength
  • Reduced blade scratches/weeping  increases first pass quality
  • Improved quality (appearance and printing) of final product will increase saleable tons
  • Cross-linkable to improve print fidelity resulting in higher printer satisfaction


Application Benefits

  • Pen-cote PR is easy and ready to use, is not alkali dependent and preparation is ammonia free :
    • Available in a pump-and-go liquid or a dry powder that easily hydrates in the coating
    • No cooking required; saving the time, hassle and EHS exposure of the cooking process
  • No sludge or foam formation as observed with protein products


“The financial impact for using biopolymers is substantial in that renewable, biobased material is highly cost effective,” said Dan Walter, VP & Director of Penford BioProducts. “In addition, the high performance capability of Pen-cote PR makes this sustainable product line a win-win from a financial, operational and corporate social responsibility standpoint.  It is further proof that we can save green by going green.”
