Water-soluble (e.g., water-soluble, water-dispersible, etc.) in that it is biodegradable and loses its integrity as time elapses in the presence of moisture. More particularly, the film contains a combination of a biodegradable polyester and a water-sensitive thermoplastic starch. The desired moisture-sensitive properties of the film can be obtained by the present invention by selectively controlling various aspects of the film construction, such as the nature of the component used, the relative amount of each component, the manner in which the film is formed, and the like.n n n n Biodegradable film, water-sensitive, water-dispersible |
