Abstract
The present invention is directed to a flushable water-sensitive film, which maintains its integrity and strength when in use, but disperses when place in contact with water, such as in a conventional sink or toilet. Moreover, the present invention is directed to a flushable release liner, which performs like conventional release papers, but adds the convenience of disposal by flushing in a sink or toilet. The present invention is also directed to products, which contain a flushable water-sensitive film or release liner.
