Abstract: A unitary foam packing element including a planar piece of foam which is precut with a plurality of score lines. The score lines define a first planar portion and a second planar portion, and enable the first planar portion to be folded over onto the second planar portion to thereby form a flat cavity between the first planar portion and the second planar portion. The score lines further define an end panel adjacent the second planar portion, which is adapted to be folded along a respective one of the score lines so as to form a first end wall of the flat cavity, and an intermediate portion between the first planar portion and the second planar portion, which is adapted to form a second end wall of the flat cavity that is opposite the first end wall.
