Abstract

The present invention provides a laminated polyester film which can be suitably used for extrusion lamination with polyolefins and comprises a coating layer having an excellent adhesion property to the polyolefins, in particular, a coating layer having a remarkably excellent adhesion property to polypropylene. The laminated polyester film of the present invention comprises a polyester film and a coating layer formed on a surface of the polyester film which is formed by applying a coating composition comprising (A) a modified polyolefin having two melting points, and at least one crosslinking agent, and then drying the coating composition applied.
