Abstract: The present invention relates to a polymeric film, which may have but is not limited to Biaxially oriented polyester, polypropylene & polylactic acid that has a soft-touch matte coating applied via an in-line coating process. This film also has an increased coefficient of friction of this surface, with a total thickness from 5 to 80 ?m. The film of this invention has excellent suitability as external packaging bags with an excellent matte appearance and soft haptic feel which, when the bags are stacked A side to A side (A side being coated), are not subject to slippage between the same. At the same time, this film has also low friction with metal, so it is easy to handle the film in the film making process which contributes to the excellent productivity.

Abstract: An in-line method to make a polymeric film with soft-feel haptic property includes the continuous, sequential steps of: (a) forming a polymer core layer of one or more polyesters; (b) optionally adding an adhesive layer and/or a skin layer over the polymer core layer to make a base layer; (c) stretching the base layer uniaxially in the machine direction; (d) coating the base layer with a liquid solution of a carbodiimide or polycarbodiimide crosslinker and a coating that includes aliphatic water-borne polyurethanes and one or more additives to enhance haptic properties, including urea-formaldehyde beads, aqueous wax dispersions and hollow sphere polymeric pigment dispersion; (e) heating the coated base layer to dry and crosslink the coating solution to form a coating layer on the base layer to create a coated film; (f) stretching the composite coated film in the transverse direction during or immediately following the drying and crosslinking step, and (g) optionally heat-treating the composite coated film to

The films and methods include a core layer comprising polypropylene, hydrocarbon resin, and polyethylene wax to improve moisture vapor barrier properties, an optional barrier layer comprising polar polymers to improve oxygen barrier properties, and optional skin layers to improve heat sealing, winding, printing, and/or adhesion.

Abstract: This invention relates to an optically clear film of predominantly thermoplastic polyester base layer and a carbodiimide-crosslinked, polyester and polymethylmethacrylate blend primer layer. The base layer preferably has a particle-free core layer and outer layers containing nonpolyester, organic and/or inorganic particles. The primer layer is preferably applied to the base layer from solution that is organic solvent-free. The primer layer and base layer composite can be laminated with a protective layer of primarily acrylic polymer to form a solar control film. Functional additives, such as UV light blockers, can be present in various layers of the solar control film. Polymethylmethacrylate in the primer, especially in combination with crosslinking by the carbodiimide, provides the acrylic coated polyester base solar control film with notably reduced iridescence. Adhesion between the acrylic layer applied from organic solvent solutions and the polyester layers is durable in moist and warm service conditions.

Abstract: A metal transfer film of thermoplastic polymer includes a polymeric carrier film, a layer of metal to be transferred onto an article, and a layer of retention adhesive suitable for bonding the transferred metal layer to a surface of the article. The transferable metal layer is adjacent between the carrier film and the retention adhesive layer. Optionally, the carrier film has a releasably adhesive layer on the side in contact with the metal. The retention adhesive is a polyvinyl amine crosslinked with citric acid. The retention adhesive is deposited on the metal layer from a liquid solution and dried to a non-tacky, solid coating enabling handling of the metal transfer film in conventional film processing unit operations. The dry retention adhesive can be activated by the metal transfer operator remotely from the adhesive application process and provides significant oxygen, moisture and aroma barrier properties to the metal covered article.

The primer layer and base layer composite can be laminated with a protective layer of primarily acrylic polymer for a solar control film. Various layers of the composite and solar control films can contain effective amounts of functional additives, such as UV light blockers.

Abstract: A composite barrier film has a base layer of polyester or polyolefin with a barrier layer modified polyvinyl amine (mPVA). The mPVA is polyvinyl alcohol/polyvinyl amine copolymer crosslinked with citric acid and an optional additional crosslinking agent such as epichlorohydrin. The barrier layer can be applied by deposition of a reactive aqueous solution onto the base layer, heating and drying to remove water and crosslink the reactants. Excellent barrier properties of the film are obtained by applying and crosslinking the barrier layer during the transverse stretching steps of a biaxial oriented polymer film continuous fabrication process. Superior barrier properties are achieved with transverse stretching by a factor of about 3-4 for polyester and 4-10 for polyolefin.

Abstract: A method is presented for making releasable transfer film suitable to provide a metalized embossed composite onto a paper substrate without a release layer between the composite and a polymeric carrier layer. The transfer film includes a polymeric base layer, an embossing material layer and a metal layer. The transfer film is bonded to the paper substrate with an adhesive layer allowing the polymeric barrier layer to peel away from and to expose the metal-backed, embossing material layer. The substrate covered with the metalized embossed composite can be used to impart holographic style images to packaging, printed media products such as magazines.
