A filling body, comprising a plurality of plastic foils, which are undulated, wherein a plastic foil has a plurality of connecting elements for connecting a plastic foil to other plastic foils via a plurality of form-fitting connections. The filling body is configured such that two plastic foils are connected to a plastic foil pair, and plastic foil pairs are connected to other plastic foil pairs. The connecting elements are positioned on the plastic foils such that upon joining two plastic foils to a plastic foil pair, the still unconnected connecting elements can be joined into connecting element pairs on opposite sides of the two plastic foils. The connecting element pairs are located exclusively in the vicinity of the edges of the two plastic foil pairs. |
