Abstract

Process for making a film or pipe by compounding an uncompounded polyolefin powder having a particle size distribution such that D95 is less than 355 μm and (D90−D10)/D50 is less than 1.2, where D95, D90, D50 and D10 are defined such that 95 wt %, 90 wt %, 50 wt % or 10 wtl % of the polymer particles have a diameter of less than D95, D90, D50 and D10 respectively, to form pellets; and then forming the pellets into a film or pipe.
