An improved packing body is formed from a strip divided into segments along fold lines. Segments along one side of a medial segment are alternately folded along the fold lines into a stack on the top surface of the medial segment. Segments on the other side of the medial segment are then folded along the fold lines into a stack on the bottom surface of the medial segments. Side segments hingedly connected to the medial or end segments can be folded along the side edges of the stack. Baffle elements can project from the surface of the strip at an angle to the longitudinal axis of the packing body. Tapered strips with a large medial segment disposed to the interior can be folded into a shape approaching spherical.
