Polypropylene compositions

Polypropylene composition, characterized in that it comprises from 50 to 90 wt % of polypropylene, from 5 to 25 wt % of high-pressure low-density polyethylene having a density of less than 940 kg m3 and from 5 to 40 wt % of high-density polyethylene having a density of more than 940 kg/m3 wherein the high-density polyethylene is bimodal and/or multimodal.

A method for the manufacture of a polypropylene composition, characterized in that from 50 to 90 wt % of polypropylene, from 5 to 25 wt % of high-pressure low-density polyethylene having a density of less than 940 kg/m3 and from 5 to 40 wt % of high-density polyethylene having a density of more than 940 kg/m3 wherein the high-density polyethylene is bimodal and/or multimodal are blended by dry blending the polymer pellets and charging the obtained blend to an extruder feeder, or by melt blending the polymer pellets in an extruder, whereby the pellets containing all the polymer components are fed to the extruder, or two of the first components are compounded together to form a master-batch and then the third component is added to the final blend as a separate operation.
