Abstract
The present invention relates to a polyester film for windows, which can block harmful ultraviolet rays from outside or prevent glare from direct sunlight and reduce thermal energy when attached to an exterior wall glass of a building or a vehicle, which can also resolve the phenomenon that an image is blurred or unclear and the image is broken when looking at an external shape through the glass, and in which a clear external shape can be confirmed even through a polyester film because fine roll-drag defects in the longitudinal that could be caused in the manufacturing process of the polyester film are not visible, and the film can be easily shrunk and peeled off even at high temperatures when applying a window film to the glass of a vehicle or a building with the polyester film being laminated with a release film.
