Abstract
A dunnage structure comprising a partition matrix made up of folded partitions, each of the partitions having two plies fused together in select locations. The partitions may be made by folding a partition blank and securing a portion of the folded partition blank to itself in predetermined locations. Passages extend through portions of the partitions to allow multiple partitions to be secured together using connectors.
