A method for manufacturing a polyestwr film is disclosed which comprises a polyester film before completion of orienting crystalization and, provided thereon, a sublayer comprising a copolymer containing 70 to 99.5 wt% of vinylidene chloride, and an antistatic layer comprising an ionic polymer, in that order. A coating solution is coated on the polyester film to form the sublayer with a dry thickness of 1 to 20 g/m<2>. The total solid content of the coating solution is not less than 4 wt%, and the coating solution contains a latex of the copolymer with an average particle size of 0.05 to 0.3 mu m. Heat is applied at a temperature not less than 30 DEG C higher than the melting point of the copolymer, and the antistatic layer is formed on the sublayer. |
