Abstract
Disclosed are high clarity films produced from semicrystalline polyesters by calendering. These films unexpectedly develop a higher peak melting point, which leads to higher thermal resistance. The semicrystalline polyesters may be biodegradable. When these calendered films are oriented, they develop unexpectedly high physical strength or clarity in comparison to films that are prepared by conventional techniques.
