LAMINATED POLYESTER FILM FOR IN-MOLD TRANSFER FOIL

摘要

PROBLEM TO BE SOLVED: To provide a laminated polyester film for in-mold transfer foil which can apply more superior matte appearance than that of a conventional film to a molded product surface, reduces unevenness of the matte appearance and has resistance to scraping during handling.SOLUTION: A laminated polyester film includes: a base material layer comprising polyester having ≥245°C of a melting point; and a matte layer located on one face of the base material layer and comprising polyester having 220-235°C of a melting point. The matte layer includes, on the basis of the weight thereof, ≥15 wt.% and ≤33 wt.% of particles. A relationship between thickness (t) of the matte layer and an average particle size (r) of the matte layer is in a range of 1.0≤r-t≤4.0 (μm), and film surface glossiness (G) on a matte face side is ≥5 and ≤25. A void generation rate of the film is ≤1.0%.
