Abstract: This multilayer body is provided with a base layer, an intermediate layer, a heat seal layer, a first adhesive layer that is provided between the base layer and the intermediate layer, and a second adhesive layer that is provided between the intermediate layer and the heat seal layer. The base layer, the intermediate layer, and the heat seal layer are configured to include polyethylene. In a case where the base layer is a stretched polyethylene film, the intermediate layer is an unstretched polyethylene film, and in a case where the intermediate layer is a stretched polyethylene film, the base layer is an unstretched polyethylene film. The proportion of polyethylene in the multilayer body is 90% by mass or more.
