A method including forming a bilayer polymer film having an oriented polypropylene film and a metallocene-catalyzed polypropylene film wherein the metallocene-catalyzed polypropylene film has a seal initiation temperature of from 80&#xb0; C. to 130&#xb0; C. A laminate including a biaxially oriented polypropylene film, a metallocene-catalyzed polypropylene film, and a substrate, wherein the metallocene-catalyzed polypropylene film is disposed between the biaxially oriented polypropylene film and the substrate.

A method of processing polyethylene for use as an extruded blow molding resin to improve the properties and processability thereof is accomplished by modifying a polyethylene resin having a molecular weight distribution (Mw/Mn) of less than about 10. The modification is carried out by the addition of a free radical initiator to the resin during extrusion of the resin to increase the rheological breadth of the polyethylene from about 10% to about 60% compared to unmodified polyethylene resin extruded under similar conditions. In another aspect of the invention, a polyethylene resin having higher melt index is processed to provide a desired final melt index by the addition of a free radical initiator where it would otherwise be necessary to utilize a resin having lower melt flow, and which is more difficult to process. Improvements in color can also be obtained.
