The present invention relates to a packaging concept includes a tubular wall member and end caps. The packaging is constructed from a sheet of flexible material wrapped into a continuous wall and fastened at the ends of the sheet material leaving open tube ends. The open ends of the tube are then closed by an end cap. The end caps are each formed from a continuous blank of sheet material. The blank includes at least three aligned cap layers. The first and second cap layers are adjacent to each other and connected by a tab connector. Each of the first and second cap layers also includes a plurality of bendable support tabs and each of the first and second cap layers includes a plurality of spaces between adjacent respective bendable support tabs. The first cap layer is folded relative to the second cap layer such that the support tabs of the first cap layer enter the spaces of the second cap layer and the support tabs of the second cap layer enter the spaces of the first cap layer. The first and second cap layers are smaller than the open tube ends and the third and fourth cap layers are larger than the open tube ends. Therefore, the first and second cap layers enter the open tube ends and the third and fourth cap layers abut the open tube ends to provide cap that can be secured to the tubular wall member by an adhesive product.
