ABSTRACT Extruding thermoplastic rubber into a thin film employing as the thermoplastic rubber a mixture of thermo- plastic rubber and sufficient amorphous polypropylene to improve the processability of the thermoplastic rubber as evidenced by the ability to achieve a draw ratio while extruding the mixture of at least 1. The films and pro- ducts formed therefrom retain characteristic elastomeric properties of pure rubber, but are significantly more processable owing to the presence of amorphous polypropylene.
