Abstract

A flame-retardant polyester film and a method for manufacturing the same are provided. The flame-retardant polyester film includes a physically recycled polyester resin and a chemically recycled polyester resin. The physically recycled polyester resin is formed by a plurality of physically recycled polyester chips. The chemically recycled polyester resin is formed by a plurality of chemically recycled polyester chips and mixed with the physically recycled polyester resin. The plurality of chemically recycled polyester chips further includes chemically recycled electrostatic pinning polyester chips. The chemically recycled electrostatic pinning polyester chips contain electrostatic pinning additives, and the electrostatic pinning additives are metal salts. Expressed in percent by weight based on a total weight of the polyester film, a content of the electrostatic pinning additives in the polyester film is between 0.005% and 0.1% by weight. The flame-retardant polyester film further includes a flame-retardant additive.
