ABSTRACT:
Monolayer and multilayer non-oriented polyester films comprising of at least one layer of an amorphous heat-sealing polyester wherein the heat-sealing polyester consisting essentially of terephthalic acid, ethylene glycol, and about 7-15 mol % cyclohexanedimethanol. The heat-sealing polyester has a heat of fusion greater than 0.5 cal/g and is sufficiently crystallizable to allow the drying of mixtures of the heat-sealing polyesters with other crystallizable polyesters without sticking. Multilayered films also contain a layer of an amorphous crystallizable polyethylene terephthalate.
