POLYESTER FILM

摘要

Monolayer and multilayer polyester film which comprises at least one layer of a heat-sealing polyester which is crystallizable to the extent of allowing mixtures thereof to be made with other crystallizable polyesters for crystallization without sticking is disclosed. The heat-sealing polyester is polyethylene terephthalate modified with about 7-15 ml. % cyclohexanedimethanol. In multilayered films, another layer of readily crystallizable polyethylene terephthalate is used.
