(57) [Abstract] [Purpose] Adhesiveness of a metal plate, can-making process after bonding with the plate, for example, deep-draw processability when forming a metal can by deep-drawing, impact resistance after can-making. It is to provide a polyester film having excellent properties and fragrance retaining properties. [Structure] The melting point of the polymer is 210 to 245 ° C., the glass transition temperature is 50 ° C. or higher, and the terminal carboxyl group concentration is 35. A polyester film for laminating and processing metal plates, comprising a copolyester having an equivalent amount of 10 6 g or more. |
