A film that is both biodegradable and flushable, and yet can still act as a barrier to water or other fluids during use, is provided. More particularly, the film contains a water-dispersible core layer that helps the film to lose its integrity after being flushed, as well as a water-barrier skin layer that helps maintain the integrity of the film during use. The nature and relative concentration of the components in the water-barrier layer are selectively controlled to achieve a combination of different functions. That is, the majority of the polymers employed in the water-barrier layer are biodegradable polymers that can be degraded by microorganisms while in an aqueous environment (e.g., septic tank, water treatment facility, etc.). To even further enhance the overall renewability of the layer, a relatively high amount of the biodegradable polymers are starch polymers, which are also renewable. The starch polymers can also minimize the degree of stickiness in the film, which can sometimes result from certain types of synthetic polymers. Even at a high starch content, the present inventors have discovered that films may still be readily formed by using synthetic biodegradable polyesters in combination with the starch to facilitate melt processing.Film à la fois biodégradable et rinçable, et pouvant encore servir de barrière à l'eau ou à d'autres fluides en utilisation. Plus particulièrement, le film selon l'invention comprend une couche centrale dispersable dans l'eau qui contribue à la perte d'intégrité du film après rinçage, ainsi qu'une couche de peau faisant barrière à l'eau qui contribue au maintien de l'intégrité du film en utilisation. La nature et la concentration relative des composants dans la couche faisant barrière à l'eau sont sélectivement contrôlées pour atteindre une combinaison des différentes fonctions. C'est-à-dire que la majorité des polymères utilisés dans la couche faisant barrière à l'eau sont des polymères biodégradables qui peuvent être dég
