| 发明名称 | Polyester composition and polyester film | ||
| 摘要 | The present invention is a polyester composition for a film, wherein the polyester composition comprises a masterbatch polyester composition including 1.0 to 2.0%, by mass of inorganic particles having an average particle diameter of 0.5 to 3.0 μm and having been prepared using a polycondensation catalyst containing, and an inorganic particle-free polyester resin in a mass ratio of 1:15 to 35; and wherein the polyester composition will cause little filter clogging and can provide a polyester film that is excellent in slipping properties, running properties and wear resistance and will suffer from little deterioration in quality due to defects or insoluble particles located on the film. | ||
