Title: LAYERED FILM
Abstract:
A layered film which comprises a base layer (layer A) comprising a biaxially oriented polyester film and a coating layer (layer B) disposed on at least one surface of the base layer, wherein the layer A in analysis by X-ray diffractometry has a (100)-plane crystal size of 4.5 nm or larger but less than 6.0 nm, the higher of the degrees of 150ºC 30-minute heat shrinkage of the layered film respectively along the longitudinal and transverse directions is 0.5-2.5%, the layer B is at least one of the outermost layers, and the surface on the reverse side from the surface coated with the layer B has a center-line average roughness (SRa) of 5-15 nm. Due to this, a layered film which is excellent in terms of suitability for winding and processability and is capable of giving printed matter having a higher gloss is provided.
