Abstract
The present invention is directed to a novel process of making water-sensitive products. In addition, the present invention is directed to water-sensitive products, which maintain their integrity and strength when in use, but dissolve or disperse when place in contact with water, such as in a conventional toilet. Moreover, the present invention is directed to water-dispersible products, including flushable products such as release liners, product packaging, etc., which contain a water-sensitive film strategically coated with a discontinuous hydrophobic material to provide water protection to the film.
