Abstract: Described are methods for producing biaxially oriented thermoplastic crystallizable films, such as polyester terephthalate (PET) films, that are easy to handle, have at least one surface that can produce high quality finishes in In-Mold Decoration processes (IMD), and have anti-static properties.

Abstract: The present invention is directed to a multilayer film having, as its main component, a hydroxy acid polymer with improved gas barrier and optional heat sealability. The oriented film of predominately hydroxy acid polymer having controlled shrink can be produced by melting and coextruding a hydroxy acid polymer with a much thinner layer of an amorphous aromatic copolyester to form a multilayer film that is quench cooled, then biaxially stretched at a process temperature above the glass transition and below the cold crystallization temperature of the hydroxy acid polymer. A heat-setting treatment with a controlled relaxation of the film above the hydroxy acid polymer glass transition temperature and below its melt temperature may be used to control shrinkage. The films thus obtained are vacuum metallized on the aromatic copolyester surface to produce environmentally friendly packaging from predominately renewable resources having improved gas barrier properties.

The invention also relates to methods of making and using the heat sealable, peelable seal films, having improved low seal initiation temperature.

Abstract: Methods and apparatuses for masking the edges of a substrate when performing direct or reverse gravure coating using a kiss-coat configuration, particularly useful for in-line coating of biaxially oriented polymeric films. The methods and apparatuses include a masking plate configured to prevent the edge of a portion of a substrate from contacting a gravure roll, the masking plate includes a top portion having a Rockwell B hardness equal to or greater than 80, and a thickness of between 0.03125 inches and 0.375 inches. This masking plate prevents build-up of coating on the edges of the substrate which otherwise can cause film orientation production instabilities such as film breaks, sticking to tenter clips, and/or edge trim recycling incompatibilities. The masking plate provides a masking method that is effective and durable, minimizing production downtime and maintenance.

Abstract: Described are methods for recycling biaxially oriented thermoplastic crystallizable films, such as polyester terephthalate (PET) films, that have been coated with various polymers or waxes that are immiscible in the primary molten thermoplastic. The resultant processed recycle can be used to make new biaxially oriented thermoplastic films while avoiding process instability and optical defects in the finished film associated with immiscible polymeric and/or wax coatings.

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: 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 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.
