Filed:

Jan 21, 2001

Appl. No.:

09/767113

Inventors:

Mingliang Lawrence Tsai - Holmdel NJ
Yash Pal Khanna - Morristown NJ
Joseph Edgar Mackey - East Hanover NJ

Assignee:

AlliedSignal Inc. - Morris Township NJ

International Classification:

B32B 2708

US Classification:

428422, 428421, 428515, 428516, 428520, 428522, 428523, 428910

Abstract:

The present invention provides highly oriented multilayer films. They are produced by coextruding or laminating films having at least one layer of a fluoropolymer, at least one layer of a polyolefin homopolymer or copolymer and an intermediate adhesive layer of a polyolefin having at least one functional moiety of an unsaturated carboxylic acid or anhydride thereof. With this structure the polyolefin layer allows the fluoropolymer layer to be stretched up to ten times its original length. Such a high orientation ratio for the fluoropolymer film increases the mechanical strength, toughness, and water vapor barrier properties of the film while using a thinner gauge fluoropolymer film. Coextrusion processing can be done at higher temperatures, i. e. in the range of from at about 280Â C. to about 400Â C.

US Classification:

Abstract:

The present invention provides biaxially oriented multilayer fluoropolymer films. They are produced by coextruding or laminating films having at least one layer of a fluoropolymer, at least one layer of a thermoplastic homopolymer or copolymer and an intermediate adhesive layer which is preferably a polyolefin having at least one functional moiety of an unsaturated carboxylic acid or anhydride thereof. With this structure the thermoplastic layer allows the fluoropolymer layer to be biaxially stretched many times its original length. A high orientation ratio for the fluoropolymer film increases the mechanical strength, toughness, and water vapor barrier properties of the film while using a thinner gauge fluoropolymer film. Coextrusion processing can be done at higher temperatures, i. e. in the range of from at about 280. degree. C.

Abstract:

A method of producing highly oriented multilayer films comprising laminating films having at least one layer of a fluoropolymer, at least one layer of a polyolefin homopolymer or copolymer and an intermediate adhesive layer of a polyolefin having at least one functional moiety of an unsaturated carboxylic acid or anhydride thereof. With this structure the polyolefin layer allows the fluoropolymer layer to be stretched up to ten times its original length. Such a high orientation ratio for the fluoropolymer film increases the mechanical strength, toughness, and water vapor barrier properties of the film while using a thinner gauge fluoropolymer film.

International Classification:

B32B 3100

US Classification:

428220

Abstract:

An improved polymer sheet. The improvement is at least one surface polymer film layer and at least one fabric veil. A veil is laminated between each surface polymer film layer and the polymer sheet. There is a method of heating a polymer sheet containing the improvement of the present invention.
