Abstract: A multilayer film is provided that comprises a nylon skin layer, a buried high density polyethylene layer, and a sealant layer, for use, for example, to form a package for dry food products. The multilayer film has a thickness of less than about 2.0 mils, such as between 0.8-1.7 mils, a moisture vapor transmission rate of less than about 0.30 g/100 in2/day, and a tear strength in the machine direction of greater than 40 grams, for instance at least about 120 grams. The multilayer film may further include a buried nylon layer and exhibit a tear strength in the machine direction of greater 190 grams.

Abstract: The embodiments of the present invention relate to multilayer thermoplastic structures having improved sealability and tearability. More specifically, the present invention relates to a multilayer heat sealant structure having at least three layers that may be coextrusion coated or otherwise laminated to a substrate, such as metallized polymeric material, foil, or other substrates.

Abstract: Packages for moisture containing products, such as cheese, including a polyamide layer, an ethylene vinyl alcohol (EVOH) layer, a sealant layer, and a moisture barrier layer located between the sealant layer and the polyamide and EVOH layers. The moisture barrier layer may contain a blend of high density polyethylene (HDPE) and low density polyethylene (LDPE). The package film has a thickness of less than 3.5 mils and a moisture vapor transmission rate (MVTR) at 100° F. and 90% relative humidity of less than 0.59 g/100 in2 per 24 hours. The moisture barrier layer minimizes the absorption of moisture by the polyamide layer, and thus prevents the package from forming a mottled appearance.

Abstract: A film structure having an inner barrier layer comprised of a blend of a polyamide and ethylene vinyl alcohol copolymer. The polyamide is present in the blend in an amount of from 15-40%, and most preferably from 25-30%. The inner barrier layer is laminated on each side with a layer of a polyamide. The preferred polyamide is nylon, and particularly nylon 6. In a preferred embodiment, the film structure is layered with an oxide or ceramic layer. Included is a method of manufacturing the film and for using the film structure to package a product in a retort packaging process.

Abstract: Fresh produce and cut flower packages are prepared from one or more polymer layers. At least one layer is a polylactic acid (PLA) film layer. Layers that can be adhered to the PLA film layer include polyolefin and polyester films. The packages have optimized moisture vapour transmission rates (MVTR) and oxygen transmission rates (OTR) to produce a shelf-life extended package that reduces growth of bacteria and prevents haze or fog on the inside of the package.

Abstract: A clear, multilayer polymeric film that is desirable for thermoforming applications. The film in its various embodiments include two inner layers of nylon and/or a core layer of ethylene vinyl alcohol or ethylene vinyl alcohol copolymer sandwiched between the two inner nylon layers. The film also has an outer layer of a heat sealable polymer and may also have an outer layer of nylon. The film is coextruded, blown into a tubular shape, oriented, and cooled by the method of tubular water quenching. The film has various improved physical properties over the prior art, including properties of “memory”, clarity, gloss and low haze.

Abstract: The present invention relates to a film structure and a method of manufacturing the same. More specifically, the film structure may include a barrier material made from EVOH, nylon or other thermally sensitive barrier material encapsulated by a first adhesive material. The barrier material and the first adhesive material form a barrier layer and a first set of adhesive layers when coextruded. The barrier layer and the first set of adhesive layers may be coextruded at the same or a similar temperature to form a first extrudate. The extrudate may be encapsulated by or otherwise coextruded with a second adhesive material to form a second extrudate at a higher temperature than the first extrudate that then may be formed into a flat sheet via a die. The first set of adhesive layers protects the barrier layer from high temperatures and long residence times related to the coextrusion/lamination process that may degrade the barrier layer.
