ABSTRACT:
Polyolefenic compositions are formed from a mixture of polyethylene and amorphous polypropylene, or a mixture of isotactic polypropylene, amorphous polypropylene and polyethylene, wherein the polyolefenic compositions are forced under heat and pressure through a shaping die thereby forming a geometrically-shaped polyolefenic article having a non-tacky surface. The compositions can have additives, fillers and other polymeric resins incorporated therein for modification of the physical and chemical properties of the polyolefenic compositions.
