DUNNAGE PLATFORM
First Claim
1. A thermoplastic dunnage platform, comprising:
- an expanded polymer core with a first side, a second side with an edge, and a width between the first side and the second side, wherein said first side is a substantially flat surface and wherein said expanded polymer core further comprises legs extending from the second side;
wherein there is a marginal space between the edge of the second side and at least some of the legs;
wherein the legs are at least twice the width of the expanded polymer core;
a first high impact thermoplastic sheet conformally combined with said expanded polymer core and having a shape defined by the expanded polymer core, wherein said first side of said expanded polymer core and part of said width is covered by said first high impact thermoplastic sheet;
a second high impact thermoplastic sheet conformally combined with said expanded polymer core and having a shape defined by the expanded polymer core, wherein said second side of said expanded polymer core and part of said width is covered by said second high impact thermoplastic sheet; and
wherein one of the first high impact thermoplastic sheet and the second high impact thermoplastic sheet is overlapped by the other of the first high impact thermoplastic sheet and said second high impact thermoplastic sheet along at least a portion of said width.

Abstract
A dunnage platform is in the general shape of a rectangular slab with legs extending form one side. The dunnage platform is made from an expanded polystyrene core. A chemical combination process is used to chemically combine portion of the core proximal to its surface with high impact polystyrene. In a first of two parts of the combination process, the core is placed in a forming mold with one of its two sides and two thirds of its thickness extending therefrom. A heated sheet of high impact polystyrene is brought into contact with the portion of the core extending from the mold. In a similar manner, the other of the two sides of the core is made to extend from the forming mold for contact with a heated sheet of high impact polystyrene.
