Abstract
A Conveyorable Plastic Thermoformed Pallet, having a support member and support legs with outer walls, internal walls and inner walls, is utilized to transport product on a conveyor system. The Pallet is made using a twin-sheet thermoforming process that requires two molds for an upper sheet of thermoplastic material and a lower sheet of thermoplastic material. The upper sheet forms a top deck of the support member and the internal walls of the support legs. The lower sheet forms the underside of the support member, the inner walls of the support legs, and leg bottoms. Both sheets are fused to form the twin-sheet outer walls. The upper sheet also forms web strips which stabilize the walls of the support legs and prevent deflection of the walls.
