摘要： 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.

摘要： 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.

摘要： A laminate film including a first polylactic acid layer; a second metal-receiving layer including PVOH, EVOH, or a blend thereof on a side of the first polylactic acid layer; and a metal layer deposited on a side of the metal-receiving layer opposite the polylactic acid layer. The metal-receiving layer may be coextruded with the polylactic acid first layer or may be a coating applied to one side of the polylactic acid first layer. This laminate film exhibits excellent gas and moisture barrier properties, appearance, and metal adhesion. It may also include a heat sealable or winding improving layer on the side opposite the metal receiving-layer of the first polylactic acid layer.

摘要： A laminate film including a first polylactic acid layer; a second metal-receiving layer including PVOH, EVOH, or a blend thereof on a side of the first polylactic acid layer; and a metal layer deposited on a side of the metal-receiving layer opposite the polylactic acid layer. The metal-receiving layer may be coextruded with the polylactic acid first layer or may be a coating applied to one side of the polylactic acid first layer. This laminate film exhibits excellent gas and moisture barrier properties, appearance, and metal adhesion. It may also include a heat sealable or winding improving layer on the side opposite the metal receiving-layer of the first polylactic acid layer.
