Abstract
A light-weight side gusset for a bag is manufactured from a formed composite frame having a peripheral raised region and a depressed central region. An opening is formed through the depressed central region to form a relatively narrow border portion around the inner periphery of the raised region. A central panel corresponding in configuration to the outline of the depressed region is attached to the border portion of the depressed region to cover the opening therethrough. The composite frame is made up of a moldable substrate, e.g. ethyl vinyl acetate foam, an outer layer wear-resistant material, e.g., high-denier nylon or poly/nylon combination, and, preferably, an inner adherent layer, e.g., the loop half of a hook-and-loop fabric. A complete bag is assembled by securing two such gussets to the body of the bag. A drop-in liner is attached to the inner surfaces of the gussets to line the interior of the bag.
