Abstract
The present invention is directed to a flushable release liner. The flushable release liner is formed by applying a release coating onto at least one surface of a water-sensitive film. The flushable release liner maintains its integrity and strength when in use, but disperses when placed in contact with water, such as in a conventional sink or toilet. Moreover, the present invention is directed to water-dispersible products, including flushable products, which contain the flushable release liner.

A flushable laminate having release characteristics, said laminate comprising:
- a two layer polymer film, wherein the two layer polymer film comprises:
- a first polymer film layer comprising a water-sensitive film;
- and
- a second polymer film layer comprising a continuous coating of polymeric material on a surface of the water-sensitive film, wherein the coating adheres to the water-sensitive film and provides release characteristics to the laminate.
A flushable release liner comprising:
- a two layer polymer film, wherein the two layer polymer film comprises:
- a first polymer film layer comprising a water-sensitive film;
- and
- a second polymer film layer comprising a substantially uniform, continuous coating of polymeric material on a surface of the water-sensitive film, wherein the coating adheres to the water-sensitive film and provides release characteristics to the liner.
