Abstract
A pallet system includes a pallet body. The pallet body is formed from a first, independently formed first portion and a second blow molded second upper portion insert molded to the first portion. The pallet body may have two to eight recesses for forklift truck fork access. The second upper portion has a generally rectangular surface for carrying loads. The portions may have anti-skid properties, for example, a knurled topside surface or rubber coated bottom. At least one foot is attached to the second upper portion by insert molding. At least one runner may be attached to each foot to form part of the first portion. At least one stringer is attached to each runner to add further stability to the pallet. The runners and feet have channels or protruding members to effectively mate with the second upper portion. The system may also have top cap and tie members to affix the cap to one or more pallet bodies.
