Abstract
Abstract The loose fill packaging material of the illustrated embodiment comprises a plurality of free-flowing elements of, for example, expanded polystyrene. Each packaging element of the embodiment is of a block-like E-shaped form which includes three leg portions which define a pair of recesses between the legs. The width of the recesses is less than the width of the leg portions and, in use, the leg portions of one element do not fit within the recesses of another element. Instead, the packaging elements abut one another, rather than interlock, while forming a mass of resilient packaging material about an item packaged therewithin.
