Abstract

Process for biaxially orienting thermoplastic films, characterized in that the virtually amorphous polyethylene terephthalate film is stretched at a temperature higher than its second order transition point, first in its manufacturing direction and then in the transverse direction, in the first direction the The film is stretched at a draw ratio of 3.75: 1 to 4.75: 1 and maintained during said tension at a low temperature and for a short time, above its second order transition point, thereby that the density of the film after stretching it in the direction of its preparation, does not exceed 1,365.
