An end cap (10) has a rigid cup-like configuration and comprises a flat end portion (11) and a tubular side portion (12) extending from the end portion to form a skirt. The side portion is provided with strengthening ribs (13) and a polygonal end flange (14). The end caps are placed on opposite ends of a roll of sheet material and are bound to the roll by tapes (24) which are located in channels (15) in the end caps and pass longitudinally alongside the roll. The roll may be stood upright on an end cap, and the end caps protect the roll. A ribbed protective sheet (21) may be wound around the roll before the end caps are placed on the ends of the protective sheet.
