Abstract
A film for laminating glass including: a first surface layer; a second surface layer disposed opposite to the first surface layer; and at least one sound insulating layer disposed between the first surface layer and the second surface layer, wherein the film for laminating glass has a L/F value reduction rate [G_L/F(A,B)] of 0.07/° C. or less at a temperature range of 20 to 35° C.
