International Classification:

A61F 13/02
A61L 15/16

US Classification:

424448000

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 μm 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.

US Classification:

426125, 26417316, 428412, 426396

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 CH(COOH)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.
