Each indented structure is separated from some or all of adjacent ones of the indented structures by the raised structures. The raised structures form rows of peaks and interconnecting saddles. Microchannels extend along adjacent ones of the indented structures and the interconnecting 16 saddles and intersect the corrugation valleys at an angle in the range of 20 to 75 degrees. The surface texturing may be or include wavy paral- lel grooves in an upper edge region adjacent the upper edge and a low- er edge region adjacent the lower edge and may be or include parallel 6 groove segments in the bulk region that are oriented obliquely to upper and lower edges of the structured packing sheet.
