ABSTRACT:
A void fill material (10) can be formed from ordinary scrap cardboard into an interlocking packaging material. Each piece of the material (10) has a primary section (20) defining a primary plane. In a preferred embodiment, a first, second and third finger (22, 24, 26) extend from the primary section (20). The primary section (20) and each finger (22, 24, 26) have a length to width ratio between 3:1 and 1:1. The first finger (22) extends from one side of primary section (20) while the second and third fingers (24, 26) extend from its other side. The intersection (30, 32, 34) between each finger (22, 24, 26) and the primary section (20) is scored, thus allowing the fingers to be bent away from the primary plane. The cushioning benefit of the void fill material (10) is improved by the ability of the deformed fingers (22, 24, 26) to interlock with the fingers of the other void fill material pieces.
