摘要:
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.

摘要:
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.

摘要:
This invention relates to a highly optically clear, composite film having a predominantly thermoplastic polyester base layer and a primer layer of a polyester and polyurethane blend composition. The base layer preferably has an A/B/C layered structure with a substantially particle-free core layer B of polyester and outer layers A and C of polyester containing nonpolyester, organic and/or inorganic particles. The primer layer is preferably applied to the base layer from solution that is organic solvent-free and 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. Various layers of the composite and solar control films can contain effective amounts of functional additives, such as UV light blockers. Polyurethane in the primer, especially in combination with crosslinking by the carbodiimide, provides the acrylic coated polyester base solar control film with notably reduced iridescence and durable adhesion between polyester and acrylic layers in moist and warm service conditions.

Adhesion between the acrylic layer applied from organic solvent solutions and the polyester layers is durable in moist and warm service conditions.
