Abstract: A packing material unit for liquid-gas contact apparatus which has a first plurality and a second plurality of loops (15) being at a first angle (loop 15) or a second angle (loops 15′ and 15″), respectively, the second angle being the opposite of the first angle, with the first loops and the second loops alternating, and an interior support for maintaining the loops of at their respective angles. The loops have an interior point and an exterior point, and an interior support connects the interior points. There is also an exterior ring (25) for connecting the exterior points of the loops. The loops, interior support, and exterior ring also have a plurality of protuberances (35, 65, 95).
