A regular packing element designed for material exchange and/or heat exchange columns comprising;

• in alternation a plurality of strips, each strip being corrugated, of generally rectangular shape,
• the strips being placed one against the other so that the corrugations crossing the strips are oriented at between 50° and 100° to the corrugations of the adjacent strip, thus forming a corrugated-crisscross structure,
• at least one bandlet contacting simultaneously at least one first ridge of a strip and at least one second ridge of the strip, the second ridge being adjacent to the first ridge,
• wherein the or each bandlet is cut out of the strip so as to leave a slot in the corrugation.
