摘要:
A metallized laminate film exhibiting improved moisture barrier property as well as maintaining a high bio-polymer content and degradability property is disclosed. The laminate film includes a first core layer of polylactic acid polymer and a second skin layer comprising a polyolefin metal receiving layer. The metal receiving layer or the core layer, or both, may be blended with an amount of polar-modified tie-resin to improve bonding. Alternatively, a discrete tie-resin layer may be interposed between the polyolefin metal receiving layer and the crystalline polylactic acid polymer core layer. The polyolefin metal receiving layer may be discharge-treated on the side opposite the core layer and metallized.

A polyolefin multilayer film containing a polyolefinic core layer and a first polyolefin skin layer of a blend, wherein the first polyolefin skin layer does not contain a thermoplastic or natural rubber and provides a cold seal receptive surface for a cold seal adhesive is disclosed. The blend includes an ethylene propylene random copolymer at 50-90 wt. % of the skin layer and metallocene catalyzed plastomer at 10-50% wt. % of the skin layer, a metallocene catalyzed isotactic polypropylene polymer or a butene propylene copolymer that contains from 5 wt % to 22 wt % of butene.

摘要:
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.
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.

The laminate film may further have additional layers such as a heat sealable layer disposed on one side of the 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.
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.
