Abstract
A packing for a mass transfer column for absorption, desorption, rectification or extraction processes, includes a packing bed having a packing element, a tubular shrink film shrunk onto at least a portion of a periphery of the packing element, and a baffle arranged at the periphery of the packing element to prevent a wall effect in the column. The baffle has a conical edge which extends outwardly with respect to the shrink film and is made of plastic.
