Coated film polyesteris a kind of thick film material made of polyethylene terephthalate by extrusion and then drawn. Coated film polyester is widely used in the FRP industry, building materials industry, printing industry, medical and health. Our country-coated polyester film industry is late to develop, but relying on policy support, industry capital investment, and other advantages, the industry is developing rapidly.

Coated film polyester has a wide range of applications due to its excellent physical, chemical, and mechanical properties, at present, it has been widely used in consumer electronics, electrical and Electrical, optics, architecture, packaging decoration, and photovoltaic and many other fields. With the continuous development of science and technology, various emerging industries continue to emerge, coated polyester film's application and use of the scene is also constantly expanding innovation. With the continuous improvement of performance and quality requirements of downstream customers, the existing conventional coated polyester film can not meet the new market demand for coated polyester film products. Therefore, in order to improve the performance and quality of the coated polyester film, the manufacturers of coated polyester film need to innovate the production process of coated polyester film and produce a more diverse range of products, which will greatly enrich the range of coated polyester film products. The upstream coated film polyester industry is the petrochemical industry. The main raw materials are polyester chips, functional masterbatch, and so on. The downstream industry includes coating, coating, packaging, etc., the final application areas are packaging materials, electronics, electrical, automotive, and construction production areas.

Coated film polyester companies to expand downstream to improve the value-added products, directly to customers with the ultimate service. At present, in addition to the production of the high-performance functional film, differential layout, and integration of industrial chain, improve industrial value-added, but also become one of the industry's development trends.
