摘要： Disclosed is a process for a film or sheet by calendering a polyester composition, comprising one or more semicrystalline polyesters and a release additive, at a maximum temperature below the upper temperature of the melting point range of each of the polyesters in the composition. The polyester composition may comprise one or more biodegradable polyesters such as, for example, aliphatic-aromatic polyesters. The calendered polyesters can form tough, flexible films without the addition of a plasticizer. The film and sheet can have optical and physical properties that make them suitable as a replacement for some plasticized PVC films. Also disclosed is a polyester composition for calendering comprising an aliphatic-aromatic polyester.

摘要： 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.
