Zusammenfassung:	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. L'invention porte sur un procédé, qui comprend la formation d'un film de polymère bicouche comportant un film de polypropylène orienté et un film de polypropylène catalysé au métallocène, le film de polypropylène catalysé au métallocène ayant une température de début de thermosoudage de 80°C à 130°C. L'invention porte également sur un stratifié, qui comprend un film de polypropylène biorienté, un film de polypropylène catalysé au métallocène, et un substrat, la spire de polypropylène catalysé au métallocène étant disposée entre le film de polypropylène biorienté et le substrat.
