摘要

The cushioning layer comprises two separate layers (1) of cardboard , especially corrugated cardboard, with a series of holes (2). The layers may be held apart by a frame around its edge with connectors. The cushioning layers are preferably arranged so that the direction of the corrugations in one layer is perpendicular to that in the next.
