Title:
MULTILAYER COMPOSITE AND METHOD OF MAKING SAME
Document Type and Number:
WIPO Patent Application WO2004101274
Kind Code:
A3
Abstract:
A multilayer composite has a generally adhesion resistant, protective layer and an adjacent second polymeric film. The composition of the protective layer includes a fluoropolymer and the second polymeric film is a polymer free of fluoropolymer. The size of the protective layer facing the second polymeric layer is rendered bondable to the non-fluoropolymer of the second polymeric layer prior to assembling the layers in the composite. The composite is well adapted to being produced in a vertical coating tower. The tower utilizes a carrier web onto which the fluoropolymer layer and second polymeric layer are deposited from respective casting films. Mirror image composites can be formed simultaneously on opposite sides of the carrier web.
