Evaluation of Cushioning Materials for Munitions Packaging

At the request of the Army Material Command (SMCAR) the Air Force Packaging Evaluation Activity has performed extensive dynamic cushioning tests on four grades of polyethylene cushioning material. The purpose of this testing was to generate new cushioning design curves that would define the cushioning properties of polyethylene over a greater range of drop heights and material thicknesses than those curves presently available. It should be noted that all testing was performed on old materials blown with a chlorofluorocarbon (CFC) blowing agent. Therefore, the curves generated may not be representative of current materials produced using CFC free blowing agents.
