MISCIBLE POLYESTER BLENDS AND SHRINKABLE FILMS PREPARED THEREFROM

摘要

Disclosed are polyester blends useful for the preparation of heat-shrinkable films, and heat-shrinkable films prepared therefrom. The heat shrinkable film may be oriented in the machine direction to produce films with high machine-direction shrinkage but low transverse growth or shrinkage. The films are useful for roll-fed, shrink-on label applications. Also disclosed are heat-shrinkable roll-fed labels prepared from reactor-grade polyesters.
