Described is a mono-axially oriented polyolefin film including a core or base layer containing a plurality of voids formed by a cavitating agent, wherein the film is oriented at least 4 times in the machine direction, and exhibits excellent tear resistance in the transverse direction.

Tear resistant mono-axially oriented propylene-based film

A multi-layer biaxially oriented polypropylene (BOPP) film with a novel formulation which exhibits matte appearance is disclosed. This improved formulation comprises a blend of high density polyethylene (HDPE), medium density polyethylene (MDPE), low density polyethylene (LDPE) or linear low density polyethylene (LLDPE) with polypropylene (PP) used in the core layer to achieve a matte appearance low gloss PP-based film that still exhibits typical properties of BOPP films with significantly lower haze than conventional matte films. The multi-layer BOPP film has additional layers such as a second polyolefin resin-containing layer, a metal layer, or combinations thereof.

Biaxially oriented matte polypropylene film

A multi-layer biaxially oriented high density polyethylene (OHDPE) film with a novel formulation which exhibits superior heat seal properties is disclosed. This improved formulation comprises a blend of a single grade of high density polyethylene (HDPE) or several grades of high density polyethylene (HDPE) with a nucleating agent (NA) used in the core layer to achieve a lower sealing initiation temperature, higher heat seal strength and broader sealing temperature range HDPE-based film that still exhibits typical properties of OHDPE films and a lower haze than conventional OHDPE films. The multi-layer BOPP film has additional layers such as a third polyolefin resin-containing layer, a metal layer, or combinations thereof.

Biaxially oriented high density polyethylene film with improved sealant layer

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.

Biaxially oriented cavitated polylactic acid film

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/m/day or less at 38&#xb0; 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.

Biaxially oriented polylactic acid film with reduced noise level and improved moisture barrier

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.

Biaxially oriented polylactic acid film with reduced noise level

Embodiments herein relate to a polyolefin-containing film comprising a solidified form of a melt, the melt comprising at least 1 weight percent shredded recycled crosslinked vinyl-alcohol polymer coated polyolefin material and an amount of a compatibilizing agent and/or an un-crosslinking agent configured to un-crosslink the crosslinked vinyl-alcohol in the melt, the polyolefin-containing film having an average dimple count of less than about 50 dimples/4 in, and method of manufacturing the same.

Recycled crosslinked vinyl-alcohol polymer coated films and methods to manufacture the same

Metallized multi-layer biaxially oriented polylactic acid base polymer (BOPLA) films that exhibits improved barrier properties and metal adhesion. The films include a core layer including crystalline polylactic acid base polymer, a first skin layer consisting essentially of amorphous polylactic acid base polymer, and a metal layer on the first skin layer. The films may include a second skin layer consisting essentially of amorphous polylactic acid base polymer.
