Abstract: A composite structure suitable for making transdermal delivery devices includes in sequence: (a) a liner film layer; (b) a containment layer having from zero to 15 wt. % content of vinyl acetate repeating units, the layer including either a thermal bonding copolyester resin or a combination of an ethylene-vinyl acetate component and a nonpolar polymer; and (c) a polyester film layer less than 20 ?m in thickness. A drug layer lies either between the liner film layer and the containment layer or within a concave depression in the containment layer. A composition including an ethylene-vinyl acetate component and an ABA block copolymer, wherein the A segments of the block copolymer are styrenic segments, is also provided. The composition includes between 1 and 15 wt. % of vinyl acetate repeating units, based on the total weight of composition exclusive of any solvents.

Abstract: A heat-sealable, coextruded composite polymeric film comprising a substrate layer comprising a first copolyester material having on a surface thereof a heat-sealable layer comprising a second copolyester material wherein: (i) the first and second copolyester materials are different from each other; (ii) the copolyester of the substrate layer comprises an aromatic dicarboxylic acid and a saturated aliphatic dicarboxylic acid of formula CnH2n(COOH)2 wherein n is 2 to 8; (iii) the heat-sealable layer comprises one or more wax(es); and (iv) the composite film is shrinkable or thermoformable; and the use thereof as a packaging film, particularly as, or in the manufacture of, a lidding film for heat-sealing to a receptacle containing a food product.

Abstract: A method treats an article and more specifically an aircraft surface in order to prevent icing and to provide a coating that emits very low volatile organic compounds (VOC) during application and setting. Icing on critical aircraft surfaces creates dangerous conditions that impair the stability of the aircraft. The specific areas are referred to as “cold-soak” conditions and some areas on the “leading edges” of the wings. The invention eliminates icing on these surfaces. Ice will not form on the surface of certain polymer coatings with low surface energy such as Teflon. This is a consequence of the high contact angle between the water droplet and the surface that establishes a non-wetting surface. The invention implements such coatings and a deposition process. The coating may be used for other objects such as automobiles, consumer products, such as refrigerators, stoves, etc.
