STRUCTURALLY DURABLE, DRAPEABLE, BREATHABLE BARRIER FILM COMPOSITIONS AND ARTICLES

Document Type and Number:

WIPO Patent Application WO2003018670

Kind Code:

A3

Abstract:

A thermoplastic film, and the articles thereof, consisting essentially of vinyl copolymer which exhibits sufficient structural durability and enhanced drapeability suitable for application as a breathable barrier layer in disposable end-use articles such as disposable hygiene and protective medical/industrial products. A preferred form of the vinyl copolymer are those selected from the ethylenic acrylates, with ethyelene methyl acrylate being most preferred. Melt additives can be compounded with the ethylene methyl acrylate prior to extrusion include colorants, softening agents, UV stabilizers, and surface energy modifiers such as anti-static, hydrophobic and hydrophilic compounds.
