With today's high standards of technology, transportation stresses can be almost completely described so that certain conclusions for the packaging container can be drawn. But an optimized, cost-efficient container is only possible, if the material behaviour and the environment of the packaging material used are known /1/. Foams belong to the most important class of packaging materials. Their dynamic behaviour is usually qualified by empirical property-values which are not suitable for the construction of packaging containers, but present only approximate values. In the context of this paper, it is shown how dynamic mechanical behaviour of a closed-cell foam can be experimentally determined. The obtained results are explained and discussed.
