Two possible two‐dimensional packing cases, one with slippery cylinders and the other with adhesive cylinders, were analyzed both experimentally and theoretically. In both cases, cylinders 10 mm in diameter and 16 mm in height were arranged inside a compaction apparatus in a random manner. The slippery cylinders were compacted to a maximum possible random closed array with little applied pressure, and virtually no further rearrangement was achieved, even by applying large additional pressure on the assembly. Compaction of the adhesive cylinders, on the other hand, occurred more gradually with applied pressure. Compaction of the cylinders resembled three‐dimensional powder compaction.
