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.

Abstract: A method for manufacturing a packaging body according to the present disclosure includes the steps of: (A) preparing a packaging material that includes an innermost layer containing a resin composition containing a polypropylene resin and a filler dispersed in the resin composition, a ratio Y/X of an average particle diameter Y μm of the filler to a thickness X μm of the innermost layer being 0.02 to 3.5; (B) producing a packaging body that has the packaging material and an oil-in-water dispersion-type content hermetically housed by the packaging material; and (C) subjecting the packaging body to a heating treatment so as to absorb oil contained in the content into the innermost layer.

Abstract: The present disclosure relates to a packaging material film including a first resin layer that contains a polyolefin resin and fillers. In a first embodiment, protrusions are formed on a surface of the first resin layer by the fillers, and a water sliding angle at room temperature of an oil film on the surface of the first resin layer is 20° or less. In a second embodiment, a ratio Y/X of a surface area ratio Y of a surface of the first resin layer with respect to an arithmetic mean height Sa X μm of the surface of the first resin layer is 0.4 to 8.0 μm−1.
