Abstract

The paper presents results of comparative investigations of packaging materials and packages made by thermoforming of polystyrene ribbon, polypropylene compound ribbon and co-extruded multi-layer ribbon containing polypropylene layer, barrier layer and polypropylene layer. The investigations have established that polypropylene compound packaging has much better characteristics, and particularly the one made of co-extruded multi-layer ribbon. In this way a better protection is provided for the packed content. Polypropylene package ensures the conditions of sterilization at temperatures up to 121 °C.
