Provided is a packaging material capable of exhibiting anti-static properties on both main surfaces. One aspect of the present disclosure includes a substrate and a sealant layer provided on the substrate, the sealant layer comprising: An ionomer composed of potassium ions and an anionic resin, and a low-density polyethylene, wherein the content of the potassium ion ionomer in the first resin layer is 725 mass perent, and a distance X of 100 or less from a main surface of the substrate opposite to the sealant layer side to a main surface of the first resin layer on the substrate side, And a distance Y from a principal surface of the sealant layer on the opposite side to the substrate side to a principal surface of the first resin layer on the opposite side to the substrate side is 15100 micro m or less.
