Examples of cushioning include foamed plastics, rubberized hair, corrugated
fiberboard, and loose-fill material such as excelsior, polystyrene, and
shredded newspapers.
Combinations of several types of cushioning (such as corrugated fiberboard
pads and less dense, loose-fill material) can be effective. Such combinations
help dissipate shock and pressure by spreading these forces over the surface
of the items.
