Abstract
The present invention is directed to a flushable release liner/wiper combination. The flushable release liner/wiper combination is formed by applying a release coating onto a first surface of a water-sensitive film and an absorbent fibrous material onto an opposite surface of the water-sensitive film. The flushable release liner/wiper combination maintains its integrity and strength when in use, but loses its integrity and strength when placed in contact with water. The flushable release liner/wiper combination quickly breaks up and disperses in a flushing toilet or sink due to the force of the flowing water on the liner/wiper combination. Moreover, the present invention is directed to methods of making the flushable release liner/wiper combination and water-dispersible products, including flushable products, which contain the flushable release liner/wiper combination.
