Title:
BIAXIALLY ORIENTED POLYETHYLENE TEREPHTHALATE FILM AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2014/030474
Kind Code:
A1
Abstract:
This film provides a polyethylene terephthalate film whereby dimensional variation in various steps can be reduced, particularly when the film is used as a substrate film for a flexible device, and that is suitable as a substrate film having minimal curl and excellent appropriateness for processing. This biaxially oriented polyethylene terephthalate film has a degree of crystallinity (Xc) of 0.35 to 0.50, the intrinsic viscosity (IV) of the resin constituting the film is 0.66-1.0 dl/g, the coefficient of thermal expansion at a temperature of 50-170°C in each of the longitudinal direction and width direction of the film is 0.29 ppm/°C, and the thermal shrinkage at 180°C in each of the longitudinal direction and width direction of the film is 0.5%-1.0%.
