Abstract
The present invention is directed to a flushable double-sided release liner. The flushable double-sided release liner is formed by applying a release coating onto both surfaces of a water-sensitive film. The flushable double-sided 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 double-sided release liners.

A flushable release liner comprising:
- a water-sensitive film;
- and
- a continuous release coating of polymeric material on both surfaces of the water-sensitive film, wherein the coating adheres to both sides of the water-sensitive film and provides release characteristics to both sides of the water-sensitive film.
A product comprising:
- a flushable three-layer laminate, wherein the flushable three-layer laminate comprises a water-sensitive film and a release coating of polymeric material on both surfaces of the water-sensitive film, wherein the coating adheres to both surfaces of the water-sensitive film and provides release characteristics to both sides of the water-sensitive film;
