    • A packaging element, for example a shock-resisting end cap for an article, is made from a pad (10) of foamed rubber or plastics, preferably closed-cell foamed polyethylene. Parallel to each edge a plurality of colinear score lines (11 to 18) are cut into one face of the pad, and between adjacent ends of each pair of colinear score lines the material is cut through to make formations (21), preferably of dovetail shape. Also, cuts (25a and 27a) are made between adjacent edge portions (24 to 27). To set-up the packaging element the edge portions (24 to 27) are turned through 90 DEG about their respective hinges formed by the scoring. The dovetail formations (21) leave apertures in the central portion (22) but because of their shape resist return to the apertures and thus hold the element in its set- up condition. in an alternative embodiment (Fig. 4) wherein the formations are rectangular in plan, the turned edge portions are held in position by strips of stiff card bridging the apertures formed in the central portion.
