Abstract: A breathable film formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure is provided. To achieve such a structure, a thermoplastic composition that contains a renewable polyester and polymeric toughening additive is extruded onto a surface to form a precursor film in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester.

This creates a network of voids located adjacent to the discrete domains.
