Abstract: Disclosed is a polymeric blend and a method of making and using the same. The polymeric blend includes 75 wt. % to 99 wt. % of a first polypropylene composition comprising polypropylene and having a melt flow rate (MFR) of A g/10 min as measured by ASTM D1238 (230° C./2.16 kg), wherein the first polypropylene composition has been previously extruded prior to forming the blend, and 1 wt. % to 25 wt. % of a second polypropylene composition comprising polypropylene and an organic peroxide and having a MFR of B g/10 min as measured by ASTM D1238 (230° C./2.16 kg), wherein the second polypropylene composition has been previously extruded prior to forming the blend, wherein the polymeric blend has a MFR of C g/10 min as measured by ASTM D1238 (230° C./2.16 kg), and wherein C is greater than A.

Abstract: A blown polypropylene film or sheet is disclosed. The film or sheet can include at least 95 wt. % of a polypropylene, and at least one β-nucleating agent or crystallization inhibitor, where the polypropylene blown film or sheet has a thickness of 0.5 mils to 15 mils, and where the polypropylene blown film has an increased dart impact strength, as measure by ASTM D1709, when compared with a second polypropylene blown film or sheet that has the same components in the same wt. % amounts as the polypropylene blown film or sheet except that the second polypropylene blown film or sheet does not include the at least one β-nucleating agent or crystallization inhibitor.
