An improved packaging container for elastic filar material is disclosed in which the wound elastic material has uniform density and no tension. The packaging container is the form of a cylindrical wall with an open top end and an open bottom end. The cylindrical wall is corrugated such that the walls have alternating grooves and ridges. Elastic filar material is circularly wound into the packaging container in multiple layers corresponding to the grooves and ridges of the corrugations. The corrugations in the cylindrical wall act to hold the windings of material in place such that interwinding, in form of tangles or overlaps, is prevented.
