Evaluation of Polypropylene and Polyethylene Cushion Wrap Materials,

Abstract

The objective of this study was to evaluate the static and dynamic cushioning properties of polyethylene wrap material in relation to polypropylene wrap material and to determine the relative cost effectiveness of the two materials in package designs. Peak acceleration (Gs) versus Static Stress curves and 'Creep' characteristics were developed for both materials. Using these data and a mathematical model, a cost analysis was accomplished. The results showed that no cost savings could be realized by substituting polyethylene for polypropylene. However, polyethylene should be considered as an alternative to polypropylene in new pack designs when item fragility and static bearing stress considerations result in equivalent material costs.
