A process for improving the quality of a thermoplastic, preferably a polyethylene terephthalate film. Slit rolls of polyethylene terephthalate film are exposed to an environment maintained at a temperature in the range of between about 15 DEG C. and 35 DEG C. above the temperature at which the rolls...

Zusammenfassung:	A process for improving the quality of a thermoplastic, preferably a polyethylene terephthalate film. Slit rolls of polyethylene terephthalate film are exposed to an environment maintained at a temperature in the range of between about 15 DEG C. and 35 DEG C. above the temperature at which the rolls were wound for a period of at least 24 hours. This process significantly decreases the formation of surface defects that otherwise form on the surface of the film in the rolls not so treated.
