Abstract:
A laminated film is provided which has excellent shape appearance at winding and also excellent processability and is capable of achieving higher glossiness of printed objects, the laminated film containing a substrate layer (layer A) composed of a biaxially oriented polyester film and a coating layer (layer B) on at least one side of the layer A, wherein the crystal size of the (100) plane of the layer A obtained by an X-ray diffraction measurement is 4.5 nm or more and less than 6.0 nm, a higher heat shrinkage ratio of the laminated film at 150° C. for 30 minutes between a heat shrinkage ratio in the longitudinal direction and a heat shrinkage ratio in the width direction at 150° C. for 30 minutes is 0.5 to 2.5%, the layer B is located on at least one outermost surface layer, and a surface opposite to the surface having the layer B has a center line average roughness (SRa) of 5 to 15 nm.
