Packaging and/or storing atactic polypropylene or other amorphous poly alpha olefins is accomplished by first heating a mass of the olefin material to a molten state and then cooling the molten mass of olefin material to an extrusion temperature. Next, the formless mass of atactic polypropylene is extruded and cut into a succession of pellets. Inert dust-like material is sprayed onto the cutting surfaces and the surface of the olefin material so that the natural tendency of the material to stick to itself and to other objects is avoided.

A method for processing an amorphous poly alpha olefin comprising the steps of: cooling a molten mass of the amorphous poly alpha olefin to an extrusion temperature; extruding the cooled amorphous poly alpha olefin through an orifice of an extrusion head; reciprocating a cutter across the orifice to cut the extruded amorphous poly alpha olefin into a succession of pellets; substantially covering the pellets with dust particles inert to the amorphous poly alpha olefin as the pellets pass through the orifice; removing the excess dust particles from the pellets; and cooling the pellets after removal of the dust particles therefrom.
