A film that is biodegradable in that it loses its integrity over time is provided. The biodegradable film includes from about 1 wt. % to about 49 wt. % by weight of the film of a matrix phase including at least one biodegradable polyester, and from about 46 wt. % to about 75 wt. % by weight of the film of a dispersed phase comprising at least one oxidized starch and at least one plasticizer, wherein the dispersed phase is dispersed in the matrix phase, and further wherein the wt. % by weight of the film of the matrix phase is less than the wt. % by weight of the film of the dispersed phase. The desired attributes of film may be achieved in the present invention by selectively controlling a variety of aspects of the film construction, such as the nature of the components employed, the relative amount of each component, the manner in which the film is formed, and so forth.
