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.

A dunnage structure comprising:
- a plurality of two-ply partitions folded into trays having open fronts, each of said partitions having a middle portion and two opposed side portions which become a horizontally oriented bottom and vertically oriented sidewalls of the tray, respectively, the middle portion being separated from the side portions by parallel fold lines, each of the partitions having a pair of passages extending through the middle and side portions and comprising opposed plies fused together at select locations;
- and
- each of said trays having connectors extending through the passages of the partitions and being secured to another tray or a top of the dunnage structure.
A dunnage structure comprising:
- a plurality of partitions, each of said partitions having a rounded edge and comprising opposed plies at least partially parent welded together, each of said partition having passages extending therethrough, each of said partitions being folded into a tray having a horizontally oriented bottom and two sidewalls extending upwardly from said bottom;
- and
- connectors extending through portions of the passages of the partitions, joining adjacent trays together.
A dunnage structure comprising:
- a plurality of partitions, each of the partitions being folded into a tray having a bottom, two sidewalls extending upwardly from said bottom and a rear wall extending upwardly from said bottom, each of said partitions having a rounded front edge and comprising opposed plies at least partially fused together and an outer face surrounding a foam interior, said partition having passages extending through the partition;
- and
- connectors extending through portions of the passages of the partitions, joining adjacent trays together.
A dunnage structure comprising:
- a plurality of trays arranged in columns, each of the trays having a bottom and two sidewalls extending upwardly from said bottom, each of said trays having a rounded front edge and being made by folding a partition comprising opposed foam plies at least partially fused together and an outer skin, said tray having passages extending along the bottom and sides of the tray;
