A polyester composition and polyester film

The present invention can provide a polyester film and a polyester film composition. Wherein the film is a polyester composition, a mass ratio of 1: 15 to 35, comprising: a polyester masterbatch composition which inorganic particles having an average diameter of 0.5 ~ 3.0μm 1.0 to 2.0 mass% and using a polycondensation catalyst containing an aluminum compound and a phosphorus compound; and a polyester resin free of inorganic particles. And said polyester film, filter clogging less slippage and mobility, good abrasion resistance, and since defects and impurities on the film quality degradation caused less.
