Abstract: 1. A built-in packing for substance and/or heat exchange between gases and liquids which is composed of several adjacent, corrugated, grid-like built-in elements (2) in which channels (3) formed by the corrugations of two adjacent built-in elements (2) extend at (α) angle to the vertical, in a straight line and in parallel and cross one another wherein continuous longitudinal struts (4) are provided in the deepest channel (3) and open into small end bearing plates (5), said bearing plates (5) form a part of an upper and a lower horizontal closed marginal strip (6) wherein said longitudinal struts (4) are connected at nodes with cross struts (8) which extend in horizontal planes parallel to the two marginal strips and with diagonal struts (12) which lead to the adjacent longitudinal struts (4). 2. The built-in packing of claim 1, wherein said channels extend at (α) angle between 10 to 80 degrees. 3. The built-in packing of claim 1 or 2, wherein each node (11, 11a) of the longitudinal strut (4) with the cross struts (8) by the diagonal strut (12) is connected to the nodes (11, 11a) of an adjacent longitudinal strut (4) by cross struts extending in adjacent horizontal planes. 4. The built-in packing of claim 3, wherein said cross struts (8) and extending diagonal struts (12) have a zigzag shape having correspondingly one longer medium arm (9, 13) and two shorter end arms (10 14), wherein said end arms (10, 14) lie in a vertical plane in which also pass longitudinal struts (4) of each built-in element (2). 5. The built-in packing of any claim 1-4, wherein said longitudinal struts (4) have a rectangular cross section. 6. The built-in packing of any claim 1-5, wherein said cross struts (4) have a square cross section. 7. The built-in packing of any claim 3-6, wherein said diagonal struts (12) have wedge-shaped cross section. 8. The built-in packing of any claim 1-7, wherein said plates (5) have a rectangular shape and their longitudinal axes extend vertically.  9. The built-in packing of any claim 1-8, wherein said plates (5) forming a part of said marginal strip (6) are connected to each other by horizontal connecting members (7). 10. The built-in packing of claim 9, wherein said connecting members (7) are fixed to the cross struts (8) arranged in adjacent horizontal planes by vertical cross pieces (15) in the form of an ice hockey stick. 11. The built-in packing of any claim 1-10, wherein said nodes (11a) of the longitudinal strut (4) with the cross struts (8) arranged in the medium portion of a built-in element are larger forming support surface. 12. The built-in packing of any claim 1-11, wherein two adjacent built-in elements are connected to each other using connecting pieces by welding. 13. The built-in packing of any claim 1-11, wherein two adjacent built-in elements are connected to each other by pins using connecting pieces. 14. The built-in packing of any claim 1-13, wherein said built-in elements (2) are made of polyethylene preferably of high density polyethylene. 15. The built-in packing of any claim 1-13, wherein aid built-in elements (2) are made of polypropylene.
