Zusammenfassung:	PURPOSE:To provide a polyester film reduced in the scratch damage at the time of transfer or seaming in a can making process using a laminate of metal and a polyester film or the scratch damage caused by the guide pin within a tape deck in a magnetic tape field. CONSTITUTION:A polyester composite film is obtained by laminating a (B-layer) composed of copolyester characterized by that 1-10mol% of total acid components is dimer acid and crystal heat of fusion is 7cal/g or more on at least the single surface of a polyester film (A-layer).
