Abstract
A method of forming a thin film strip. 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.
