BIAXIALLY ORIENTED POLYESTER FILM FOR METAL SHEET-LAMINATING FABRICATION

摘要

PROBLEM TO BE SOLVED: To provide a biaxially oriented polyester film for metal sheet-laminating fabrication which has sufficient adhesiveness even when laminating at low temperature and has excellent fabricatability without damage or peeling of a film in fabrication after lamination on a metal sheet.SOLUTION: There is provided a biaxially oriented polyester film for metal sheet-laminating fabrication comprising a lamination film in which one layer (layer A) is a copolyester layer having a heat of fusion by DSC of 10 J/g or less and a plane orientation coefficient of 0.00 or more to 0.05 or less and the other layer (layer B) is a polyester layer having a melting point of 210°C or higher to 250°C or below.
