Development of a Water Soluble Foam Packaging Material

Abstract

The purpose of this program was to investigate the feasibility of developing and reliably reproducing a water soluble foam from hydroxypropyl celluluse resin (Klucel) and to establish product parameters. The program was divided into two phases. In Phase I, the feasibility of extruding the water soluble, thermoplastic resin into a candidate packaging material was successfully demonstrated. Hydroxypropyl cellulose was extruded by conventional means into a loose-fill packaging foam having a compressive stiffness conforming to Federal Specification PPP-C-850, Cushioning Material, Polystyrene Expanded, Resilient, Class 4 (Extra Firm). In Phase II, the loose-fill foam product produced from this resin was tested . Additional investigations conducted on the loose-fill samples were: Effects of long and short term relative humidity exposure; and Solubility and dissolution rates in fresh and salt water. Long term humidity exposure caused the material to deteriorate and lose all foam cushioning properties.
