Abstract
A polyester film and a method for producing the same are provided. The polyester film includes a physically recycled polyester resin and a chemically recycled polyester resin. The physically recycled polyester resin is formed of physically recycled polyester chips, and the physically recycled polyester chips have a first intrinsic viscosity. The chemically recycled polyester resin is formed of chemically recycled polyester chips, and the chemically recycled polyester chips have a second intrinsic viscosity. The second intrinsic viscosity is less than the first intrinsic viscosity. The physically recycled polyester chips and the chemically recycled polyester chips are mixed with each other and melt extruded according to a predetermined intrinsic viscosity, so that the polyester film has the predetermined intrinsic viscosity.
