Processing Aids & Modifiers
Packaging Processed and Modified with Ease

Our processing aids and modifiers are designed to change and improve the properties of packaging films and coatings. Others help scour tough die deposits and gels in extruders.  The end result is packaging that is strong and durable.

Surlyn® Packaging Resins


When made into films, Surlyn® resins:
  • Deliver outstanding clarity, toughness, draw-down strength and puncture and tear resistance. 
  • Can be laminated with other materials.
  • Reduce rejects and raw material waste in the production line due to its strength, which is preserved even when heated.
  • Make film stretchable after only 10 seconds of heating due to the good heat absorption of Surlyn®, conserving process energy and achieving short cycle times.

DuPont scientists have developed special grades of Surlyn® for film applications, including films optimized for use on skin packaging machines.
