Calcium Carbonate in Blown HDPE Film

Many interesting developments have taken place in the film industry over the past few years due to new improved resins and the increased capability of extrusion lines.

Technical progress must however be subject to the cost factor and the use of mineral modifiers, especially calcium carbonate can play an important role. Most polymers are ductile but may become brittle under certain circumstances.
