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/m². 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 µm. Heat is applied at a temperature not less than 30 °C higher than the melting point of the copolymer, and the antistatic layer is formed on the sublayer.
本发明公开了一种聚酯薄膜的制造方法,该方法包括在定向结晶完成前的聚酯薄膜,以及在聚酯薄膜上依次设置的由含 70 至 99.5 wt%亚
氯乙烯的共聚物组成的子层和由离子聚合物组成的抗静电层。在聚酯薄膜上涂布涂层溶液,形成干厚度为 1 至 20 克/平方米的子层。涂层溶液的总固含量不低于 4 wt%,涂层溶液中含有平均粒径为 0.05 至 0.3 µm 的共聚物胶乳。在不低于共聚物熔点 30 °C 的温度下加热,在底层上形成抗静电层。
