Abstract: A support for holding sheets of flexible material such as paper, plastics and thin metal foils. The support includes an elongated frame which may be tubular or channel shaped and includes a base and side walls which defines a cavity which extends lengthwise of the frame. A U-shaped loop formed of a flexible, resilient plastic has a bail connecting a pair of legs. Each leg terminates in a distal end. The U-shaped plastic loop is positioned in the cavity of the frame with the bail of the U-shaped plastic loop extending outwardly of the cavity and the distal ends of the legs engaging the frame. The legs of the U-shaped plastic loop cooperate with the side walls of the frame to receive and retain sheets of flexible material inserted into the cavity between the U-shaped plastic loop and one of the side walls of the frame. The legs of the U-shaped plastic loop may be formed with feet that are seated in slots formed in the elongated frame.

Abstract: A laminate for forming structural members and the structural members formed thereby. The laminate has a core with opposite outer surfaces, an outer laminated sheathing attached to each of the opposite outer surfaces of the core. The core has a center film of a biaxially oriented thermoset polyester resin. Each of the outer surfaces of the core is formed of a film of a thermoplastic adhesive resin which fastens to an outer laminated sheathing. Each of the outer sheathings includes an outer film of a biaxially oriented thermoset polyester resin with the outer films of biaxially oriented thermoset resin connected by at least one center film of a thermoplastic adhesive resin. The outer films of biaxially oriented thermoset polyester resin located adjacent the core have a film of thermoplastic adhesive resin facing the outer surfaces of the core. The biaxially oriented thermoset polyester resin is preferably polyethylene terephthalate and the thermoplastic adhesive resin is polyethylene.
