Abstract
Blown films and blow molded objects may be prepared using a polyethylene composition comprising a unimodal metallocene catalyzed polyethylene copolymer. The polyethylene copolymer has high melt fow rate and good melt strength allowing it to be useful in both extrusion and injection blow molding. Blown film prepared therewith has a high level of clarity.
