Abstract

The present invention relates to a high brightness polyester film and a manufacturing method thereof. The method utilizes a three-layer co-extrusion technique to prepare the high brightness polyesterfilm through using raw materials such as regenerated polyamide ester slices and super bright polyester slices. In the method, a nylon 6 oligomer is introduced onto a polyester molecular chain segmentto reduce molecular chain structure regularity of the polyester, and an amide group of the nylon 6 increases distance from the molecular chain of the polyester, thereby improving transparency of the polyester film and improving brightness.
