ABSTRACT:

BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is generally related to the processing of thin films, and in particular to the formation of coated film strips.
SUMMARY OF THE INVENTION
The present invention is directed to a method of forming a thin film strip. In one embodiment the method comprises coating a liner substrate with a wet slurry of film forming ingredients and drying the wet slurry in a drying oven to form a film. A moisture content of the film is measured as the film exits the drying oven and the film is rewound on itself. The rewound film is then stored in a minimal moisture loss environment during a curing process.
