PE-PA RESIDUES OF COMPOSITE FILMS - PROPE RTIES AND LIMITS OF USABILITY

PE-PA multilayer compound foils are frequently used packing materials on the foodstuff sector. Remnants from the processing are high-quality raw materials but provide mixtures whose composition varies considera bly due to the diversity of recipes. The development of products presu pposes, however, a sufficient knowledge of the characteristic values o f the materials and of their boundaries. The results from a study on t he utilization of foil residues shown in this article provide the basi s for a selective use of such materials.
