Abstract: A biaxially oriented laminate film including a core layer including a blend of crystalline polylactic acid polymer and a metal salt phosphorus-containing compound nucleating agent which is biaxially oriented at low transverse direction orientation temperatures to impart a degree of cavitation around the metal salt phosphorus-containing metal such that a white opaque cavitated appearance and a lower film density and improved mechanical properties are obtained. The laminate film could further have additional layers such as a heat sealable layer disposed on one side of said core layer including an amorphous polylactic acid resin and/or a polylactic acid resin-containing layer disposed on the side of the core layer opposite the heat sealable layer, a metal layer, or combinations thereof.

Abstract: Described are metallized biaxially oriented polylactic acid (BOPLA) films with a novel formulation that exhibits a softer feel and quieter sound, without jeopardizing film making stability. It has been found that when these films are metallized, moisture barrier properties are surprisingly improved compared to conventional metallized BOPLA films. Specifically, the moisture barrier of the films may be 2.0 g/m2/day or less at 38° C. and 90% relative humidity. The films can be used, for example, in packaging applications. The films have characteristics that are beneficial to converting processes, are economical, and maintain bio-compostability similar to typical BOPLA films.

Abstract: Described are biaxially oriented polylactic acid (BOPLA) films with a novel formulation that exhibits a softer feel and quieter sound, without jeopardizing film making stability. The films can be used, for example, in packaging applications. The films can be metallized, or combined with barrier coatings or layers, for improved gas barrier properties particularly for moisture vapor transmission barrier desired in packaging applications. The films can also be printing films for packaging applications and may be transparent or matte in appearance. The films have characteristics that are beneficial to converting processes, are economical, and maintain bio-compostability similar to typical BOPLA films.
