Abstract

Se proporciona una película que es biodegradable y sensible al agua (por ejemplo soluble en agua, dispersable en agua, etc.) ya que ésta pierde su integridad con el tiempo en la presencia del agua. La película contiene un poliéster biodegradable, un almidón, un polímero soluble en agua y un plastificante. Los atributos sensibles al agua deseados pueden ser logrados en la presente invención mediante el controlar selectivamente una variedad de aspectos de la construcción de la película, tal como la naturaleza de los componentes empleados, la cantidad relativa, de cada componente, la manera en la cual la película es formada y otros.
