Abstract
A film for laminating includes an embossed surface, wherein a rad value of the embossed surface is 1 to 3 μm, where the rad value is calculated by [Formula 1] below: rad ( um ) = 1 0 0 0 Spc ( mm - 1 ) [ Formula 1 ] where, in [Formula 1], Spc is an arithmetic mean of curvatures of peak vertex on the embossed surface, which is evaluated by ISO_25178, wherein a number of peaks per 1 mm2 of the embossed surface (Spd value), which is evaluated by ISO_25178, is 200 or more and 1500 or less, and wherein a sum of maximum peak height and maximum valley depth of the embossed surface (Sz value) is 30 to 90 μm.
