Abstract
A protective packaging sheet which is particularly suitable for packaging heavy loads such as coils of sheet steel. The packaging sheet is formed from a plastics sheet material having inherently relatively low compressions strength and resistance to impact forces and bending. These mechanical properties are vastly improved in the embossed packaging sheet. At least one of the surfaces of the sheet material is provided with shaped protuberances juxtaposed with adjacent shaped protuberances to provide a gap around each shaped protuberance. The shaped protuberances are arranged in such a way that all straight lines projected onto the surface cut through the shaped protuberances in addition to the gaps.
