摘要:
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.
摘要:
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.

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:
A collapsible clothes hanger molded in one piece of a flexible material has a pair of hanger arms which are moved from a collapsed position to an extended position by one hand exerting s squeezing force on the flexible connections between the pair of hanger arms and a pair of flexible links that extend between the hanger arms and a center support member. The bendable links, whose motion is restricted by the center support member, fold upon themselves and draw the hanger arms upward into the extended position. The squeezing force which moves the hanger arms into the extended position lies in a horizontal plane so that the hand of the user can remain in a natural position during extension of the arms to a desired garment-supporting position. The hanger of a preferred embodiment is automatically locked in the extended position once this position is reached. The lock is released by again a single hand exerting a squeezing force, also in a horizontal plane, so that the hanger arms may move the collapsed position. The hanger arms, flexible links, and center support member are connected to one another by hinges. The locking mechanism of the preferred embodiments includes a push button release and extends from each of the hanger arms between the hinge connected to the center support member and the hinge connected to the flexible links.

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.
