ABSTRACT:
Polypropylene films having a coextruded ethylene-vinyl alcohol (EVAL) layer cannot be readily oriented because the orientation temperature for the EVAL layer is somewhat higher. By adding an aryl sulfonamide, such as p-toluenesulfonamide to the EVAL layer its orientation temperature is reduced enabling orientation of the composite film.
