    Abstract: A packaging is provided including: a base layer including at least one layer of a biaxially oriented resin film; and a sealant layer including at least a first thermoplastic resin layer and a second thermoplastic resin layer, in which the base layer, the first thermoplastic resin laser, and the second thermoplastic resin layer are laminated in this order, a density of a first resin forming the first thermoplastic resin layer is higher than a density of a second resin forming the second thermoplastic resin layer, the density of the first resin is 0.90 g/cm3 or higher, the density of the second resin is 0.92 g/cm3 or lower, and the second thermoplastic resin layer contains 200 to 2000 ppm of a lubricant including at least one of a fatly acid amide lubricant and a fatty acid ester lubricant.
