Abstract: In zig-zag sheet metal column packing, a proportion X of the openings has a spacing b which is no greater than 0.4a from a fold edge. The proportion X is at least 60%. Preferred Features: X is at least 80% or 90%. Dimension b is 0.3a or 0.2a at most. The angle of folding is 40-120 degrees , preferably 60-90 degrees . Openings take up 5-40%, preferably 10-20% of the folded area. Openings are rectangular with aspect ratio 5:1 to 1:1, preferably 3:1 to 2:1. The longer side of the opening, is parallel to the folded edges. In a packed column, folded edges of the packing include an angle of 20-70 degrees , preferably 30-45 degrees with the column axis.
