ABSTRACT:
A tubular dunnage element or paperboard or the like has a tucked or heart-shaped radial cross section, and a slanted axial cross section. The element may be compressed by opposed inward forces along any line through the center of the element. The element is suited for use as a loose fill packing material. Serrated edges cause the elements in a bed to catch on one another, resisting the tendency of a packed article to migrate through the bed to a wall of a container under the influence of vibration occurring during shipment.
