LAMINATED POLYESTER FILM FOR THERMAL LAMINATION OF METAL PANEL

摘要

PROBLEM TO BE SOLVED: To provide a laminated polyester film for thermal lamination of a metal panel not lowering adhesion under a moist heat condition and excellent in processing characteristics. SOLUTION: One surface (A) laminated to a metal of the laminated polyester film is constituted of a mixed polyester composition (A) which is constituted of 40-95 pts.wt. of a polyester resin (A1). 15-50 mol % of the total polyhydric alcohol component is 1,4-cyclohexanedimethanol, and a melting point is 130-180 deg.C and 5-60 pts.wt. of a polyester (A2) with a melting point of 190-260 deg.C. The other surface (B) thereof is constituted of polyester (B) with a melting point of 190-260 deg.C. The degree of orientation of the surface (A) is 0.02-0.12.
