Abstract

A PROCESS TO INCREASE RESISTANCE TO TEARING IN A HEATRESETTABLE MATERIAL IS DESCRIBED,FOLLOWED BY EXTRUDING A POLYMER OF A SPECIFIED CROSSLINKING DENSITY TO PRODUCE A PLASTIC WEB. AFTER COOLING THE PLACTIC WEB IS HEATED BY CREATING A TEMPERATURE DECREASING TOWARDS ITS CORE AND STRETCHED AT CORE TEMPERATURE BELOW CRYSTALLINE MELTING TEMPERATURE OF PARTIALLY CRYSTALLINE AND CRYSTALLINE POLYMERS RESULTING IN A DISTRIBUTION OF ORIENTATION OVER THE FULL SECTION OF THE PLASTIC WEB.RESISTANCE TO TEARING WILL BE ESSENTIALLY INCREASED IN THIS MANNER BASED ON A SIMPLE,LOW-COST PRODUCTION PROCESS.
