Abstract
A shipping container following the teachings of the present invention is made by an insert molding process. The walls and bottom are each formed with structural portions that form a frame and any necessary cross bracing. A fabric covers any opening between structural portions. The fabric is placed in a mold that defines a cavity shaped like the structural portions, and thereafter a thermoplastic resin in injected. The resin intimately penetrates the fabric fibers to hold the fabric in place. The fabric may have holes formed in it to enhance the penetration of the resin. A wide variety of fabric and resins may be used.
