Abstract

A thermoformed article that is formed from a polymeric sheet having a thickness of from about 0.1 to about 100 millimeters is provided. The polymeric sheet contains a thermoplastic composition that includes a continuous phase that includes a matrix polymer. A microinclusion additive and nanoinclusion additive are dispersed within the continuous phase in the form of discrete domains, and a porous network is defined in the composition that includes a plurality of nanopores having an average cross-sectional dimension of about 800 nanometers or less.
