Abstract: An easily fabricated, yet extremely sturdy packaging filler divider for merchandise display of cartons or the like is provided which includes an elongated, tubular body with a central reinforcing sheet therein having marginal flaps extending oppositely from the sheet and connected to opposed internal sidewall portions of the body; by virtue of this construction fabrication costs are drastically reduced since the filler can be produced from a single, continuous sheet of paper stock using completely automated equipment with only two simple folds being required, and moreover the resistance to crushing or other deformation of the filler is greatly enhanced. In preferred forms, the filler is fabricated from an initially flat, precut paper blank such that the finished divider can be folded to a flat storage position when not in use.
