AbstractThin walled thermoformed articles of partially crystallized polyethylene terephthalate containing a minor component of a polyolefin which exhibit improved impact resistance and high temperature dimensional stability are disclosed herein. A method for thermoforming such articles using polyethylene terephthalate/polyolefin blends which provides improved mold release is also revealed.
