Abstract : Resilient polystyrene foams of various densities were dynamically tested (to simulate actual packaging conditions) by dropping various weights on them from a constant height and electronically recording the resulting shock in terms of maximum acceleration and dynamic set. The acceleration values were found to decrease with increasing specimen thickness. The dynamic set values in the optimum loading region did not inANY CASE EXCEED 10%. Actual packaging conditions were simulated by placing the polystyrene samples in a standard container with a simulated packaged item. The information and data obtained should serve as a guide for the use of resilient polystyrene foam as a package cushion. Use of these curves in conjunction with established prerequisites will facilitate the efficient use of these materials. (Author)
