Abstract: A packaging material film according to the present disclosure includes a first resin layer that contains a polyolefin resin and a porous filler. A ratio Y/X of an average particle size Y μm of the porous filler to a thickness X μm of the first resin layer is 0.02 to 3.5, and a content percentage of the porous filler in the first resin layer is 0.5 to 30 mass %. A packaging material according to the present disclosure includes a substrate and a packaging material film disposed on the substrate. In the packaging material, the packaging material film is formed of the above packaging material film, and a surface of the first resin layer of the packaging material film on a side opposite from the substrate is exposed.
