摘要： The present invention relates to a process for preparing a highly tensilized polyester film that has enhanced mechanical properties in both longitudinal and transverse directions. The process involves the simultaneous machine and transverse direction stretching and subsequent heat setting of a film that has already been highly stretched in the machine and transverse directions individually. During the simultaneous stretching process both the temperature and rate of linear movement of the film are controlled.

摘要： A biaxially oriented polyester film which is well balanced between sliding properties and transparency and having an enhanced uniformity in thickness is prepared by a process wherein a polyester, predominantly comprised of polyethylene terephthalate, is extruded into a sheet form extrudate; the extrudate is quenched to a temperature of below Tg to obtain a solidified, substantially amorphous film; the film is drawn in the longitudinal direction at a drawing ratio of larger than 2.4 but smaller than 6.5; the film is quenched; and then, the film is drawn in the transverse direction at a drawing ratio of at least 2.5. The drawing in the longitudinal direction is carried out in two steps wherein:(i) in the first drawing step, the substantially amorphous film is drawn in one or more stages at a total drawing zone length (l.sub.1) of at least 50 mm so that the resulting polyester film possesses a birefringence of 1.times.10.sup.-3 to 12.times.10.sup.-3 ;(ii) the drawn film is kept, without being quenched to a temperature of not higher than the Tg, in contact with a roll maintained at 100.degree. to 130.degree. C.; and then,(iii) in the second drawing step, the film is drawn at a drawing ratio of larger than 1.6 but smaller than 2.7 in one stage at a drawing zone length of shorter than l.sub.1 /2.
