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°C to 130 °C. A laminate including a biaxially oriented polypropylene film, a metallocene-catalyzed polypropylene film, and a substrate, wherein the metallocene-catalyzed polypropylene turn is disposed between the biaxially oriented polypropylene film and the substrate. |
