ABSTRACT:
A biaxially stretched polyester film is disclosed.
The biaxially stretched polyester film comprises substantially spherical silica particles of colloidal state having average diameters ranging from approximately 20 nm to approximately 200 nm in amounts ranging from approximately 0.005% to approximately 1.0% by weight based on the total weight of the polyester; and alumina particles having average diameters ranging from approximately 50 nm to approximately 500 nm in amounts ranging from approximately 0.05% to approximately 5.0% by weight, the average diameter of the alumina particles being larger than that of the silica particles.
The biaxially stretched film prepared according to the present invention has excellent surface properties such as slip property and abrasion resistance, so that the film may be used for manufacturing final products without scratches and white powders occurring thereon.
