Abstract: A multilayered packaging film having good antifog performance that is suitable for use in food packaging. The multilayered film comprises a nylon film having first and second surfaces; a sealant film positioned on the first surface of the nylon film, either directly on the first surface of the nylon film or via an intermediate adhesive; an antifog composition contained within at least part of the sealant film or coated on a surface of the sealant film opposite the nylon film; and a protective film applied onto the second surface of the nylon film.

Abstract: Oxygen barrier films having a greatly improved dynamic coefficient of friction, and specifically, oxygen barrier films having an exceptionally low dynamic coefficient of friction, reduced moisture sensitivity and good oxygen barrier properties over a wide range of relative humidities. The low coefficient of friction is obtained by using film layers which are blends of a polyamide component and a high density polyethylene which surround an oxygen barrier layer, such as an ethylene vinyl alcohol layer.

Abstract: A multilayered packaging film having good antifog performance that is suitable for use in food packaging. The multilayered film comprises an outer film attached to an inner film, which outer film is a combination of a first nylon layer, an ethylene vinyl alcohol layer attached to a surface of the first nylon layer and a second nylon layer attached to the ethylene vinyl alcohol layer. The inner film is a combination of a third nylon layer having a silicone oil on a first surface of the third nylon layer, and a sealant film on a second surface of the third nylon layer, attached either directly or via an intermediate adhesive layer. An antifog composition is either contained within the sealant film or is coated on a surface of the sealant film opposite the third nylon layer. The silicone oil effectively blocks the migration of the antifog composition into an adjacent nylon layer when the multilayered film is stored in roll form.

Abstract: Toughened biaxially oriented polyamide films prepared by dry blending i) a polyamide homopolymer, copolymer, or blends thereof; and ii) a functionalized polyolefin terpolymer comprising maleic anhydride, ethyl acrylate, and an olefin, to thereby form a dry mixture. The dry mixture is melted to form a polymer blend, which is then formed into a polymer film. The edges of the film are pinned to a casting roll, and the film is plasticized in at least one water bath. The polymer film is subsequently biaxially oriented. The result is a toughened biaxially oriented film which is resistant to pinholes, cracks, and other structural defects. Such films are particularly suited for making packaging materials for various food products.

The multilayered film comprises a nylon film having first and second surfaces; a silicone oil on the first surface of the nylon film; and a sealant film on the second surface of the nylon film, either directly or via an intermediate adhesive tie layer. An antifog composition is either contained within at least part of the sealant film or is coated on a surface of the sealant film opposite the nylon film.

Abstract: A food package comprising a two piece sealed package including metal free container and peelable lid portions which are readily separable from each other. The container is cup shaped and has a top opening and a substantially flat peripheral rim around the opening. The lid comprises a composite film having a shape which conforms to the shape of the opening and is attached to the rim. The film has a first outer polyamide or polyolefin layer attached to an inner layer of either an ethylene vinyl alcohol copolymer or a blend of a polyamide with an ethylene vinyl alcohol copolymer, which is attached to a second outer polyamide or polyolefin layer. The metal free packaged product allows the detection of metal contaminants inadvertently mixed with the food by scanning the product in the container to determine the presence of metal contaminants in the container.

Abstract: Book covers and a substantially transparent, coextruded matte, bilayer nylon film which is contact transparent to a paper stock to form a soft book cover having high scratch, abrasion and mar resistance, a soft feel and good moisture curl properties. A substantially transparent, coextruded film which has a first nylon layer attached adjacent to a second nylon layer, the first nylon layer has from about 20 weight percent to about 70 weight percent of a refractory filler based on the weight of the first nylon layer.
