Abstract: A highly optically clear, composite film has a predominantly thermoplastic polyester base layer of A/B/C-layered structure and a polyester and polyurethane blend primer layer Preferably core layer B of the base layer is substantially particle-free polyester and outer layers A and C include organic and/or inorganic particles. The primer layer is crosslinked using a carbodiimide crosslinking agent. The primer layer and base layer composite can be laminated with a protective layer of primarily acrylic polymer for a solar control film. Functional additives, such as UV light blockers can be present in layers of the composite and solar control films. The primer layer combination of polyurethane and crosslinking by carbodiimide, provides the acrylic coated polyester solar control film with notably reduced iridescence and durable adhesion between polyester and acrylic layers in moist and warm service conditions.

Abstract: A moisture vapor and oxygen transmission resistant flexible film has a polymeric base layer and a barrier layer of discrete particles of a first organic polymer dispersed throughout a matrix of a second organic polymer. Preferably, the first and second polymers are water insoluble and water soluble, respectively. The barrier layer is formed by depositing onto the base layer a coating composition of finely divided insoluble organic polymer particles suspended in an aqueous solution of the water soluble organic polymer, a crosslinking agent and surfactant. The coating composition is heated to crosslink the barrier layer polymers and evaporate solvent to provide a barrier film suitable for packaging applications. Optionally, the film can be metalized to increase barrier properties.

Abstract: A monoaxially oriented film including a metallized layer; a gas barrier layer; and a propylene-based random copolymer and at least about 3 wt % of a low density polyethylene which is oriented at least about 2.5 times in one direction and exhibits excellent linear directional tear properties parallel to the orientation direction and excellent heat seal performance in terms of high heat seal strengths and low seal initiation temperature. This film formulation and orientation is suitable for pouch applications requiring high gas and moisture barrier, an “easy-tear” linear tear feature, and excellent hermetic seal properties.

Abstract: A releasable transfer film is 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.

Abstract: A laminate film including a first polylactic acid layer; a second metal-receiving layer including PVOH, EVOH, or a blend thereof on a side of the first polylactic acid layer; and a metal layer deposited on a side of the metal-receiving layer opposite the polylactic acid layer. The metal-receiving layer may be coextruded with the polylactic acid first layer or may be a coating applied to one side of the polylactic acid first layer. This laminate film exhibits excellent gas and moisture barrier properties, appearance, and metal adhesion. It may also include a heat sealable or winding improving layer on the side opposite the metal receiving-layer of the first polylactic acid layer.

Abstract: A laminate film including a first core polylactic acid layer, a coating receiving-layer of polylactic acid, and coated on one side of the coating receiving-layer with PVOH, EVOH, a blend of crosslinked EVOH/PVOH, vinyl alcohol-vinylamine (PVAm) copolymer, anionic carboxylated styrene-butadiene copolymer (SBR) emulsion, or blends thereof. This coating may be applied after the machine-direction orientation step and dried and oriented in a transverse direction orientation oven if in-line coating is desired; or applied to the film in an off-line coating method and dried in an air flotation oven. The dried coating layer can be metallized. This laminate film exhibits excellent gas and moisture barrier properties, appearance, and metal adhesion. It may also optionally include a heat sealable or winding improving layer on the side opposite the coating receiving-layer of the core layer.

Abstract: This invention relates to a new two-component 100% solids polyurethane coating composition characterized by being free of volatile organic compounds (hence “VOC-free”). The coating composition is used to provide a durable coating on a substrate. The coating is produced by reacting a liquid polyester polyol with a polyfunctional isocyanate. Optionally, the polyol component contains a short chain polyol to provide hard segments in the resulting coating. The coating is particularly useful for providing a top coat on concrete form panels, such as plywood form panels, that are widely employed in the construction industry.
