摘要： The present invention is directed to a multilayer film having, as its main component, a hydroxy acid polymer with improved gas barrier and optional heat sealability. The oriented film of predominately hydroxy acid polymer having controlled shrink can be produced by melting and coextruding a hydroxy acid polymer with a much thinner layer of an amorphous aromatic copolyester to form a multilayer film that is quench cooled, then biaxially stretched at a process temperature above the glass transition and below the cold crystallization temperature of the hydroxy acid polymer. A heat-setting treatment with a controlled relaxation of the film above the hydroxy acid polymer glass transition temperature and below its melt temperature may be used to control shrinkage. The films thus obtained are vacuum metallized on the aromatic copolyester surface to produce environmentally friendly packaging from predominately renewable resources having improved gas barrier properties.

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 multilayer film including a first layer including a polylactic acid polymer, a second layer of a metal primer, deposited upon one surface of the first polylactic acid polymer layer, and a third metal layer deposited on the second metal primer layer. This metal-primed and metallized polylactic acid film exhibits improved moisture barrier properties versus a non-metal-primed and metallized polylactic acid film and can be used as part of a lamination structure for food packaging applications.
