    摘要： Disclosed are polyester blends that provide improved stress whitening behavior. The blends may be prepared from a polyester having crystallization half-time of at least 5 minutes and a polyester elastomer. The polyesters blends may be extruded or, in the presence of a release additive, calendered to produce film or sheet. Also disclosed are processes for making a film or sheet by extrusion or calendering the above blends and the film or sheet produced therefrom. The polyester blend and the film or sheet produced therefrom also may include plasticizers and/or flame retardants to increase their flexibility and enable their use in commercial applications requiring flame resistance. The film and sheet have excellent appearance and can be used in a wide range of decorative and packaging applications.
