Evaluation of Expanded Bead Polyethylene Foam Cushioning For Packaging.

Abstract

Expanded Bead Molded Polyethylene Foam Cushioning Material was evaluated for its static and dynamic characteristics. It was determined that the material meets the compression set and compressive strength requirements of Type I material of PPP-C-1752A, 'Cushioning Material, Packaging, Unicellular Polyethylene Foam, Flexible.' The material provides slightly better dynamic cushioning in the optimum cushioning static stress range than conventional polyethylene sheet stock materials. Application of molded polyethylene should prove to be cost effective when used in lieu of built-up cushion packs or container structures which are formed by laminating together pieces of polyethylene sheet stock.
