Abstract

The present invention provides thermoformed polyolefin foam articles and methods of their production. The thermoformed articles have a density of less than or equal to the density of the precursor foam sheets from which they are formed. The thermoformed articles may also have a thickness of greater than or equal to the thickness of the precursor foam sheets. The precursor foam sheets can be produced in an extrusion process and may be microcellular materials. A variety of thermoformed polyolefin foam articles, including deep drawn articles, can be produced.
