In the method of packing at the first stage on both sides of the cargo a vertically oriented sheet is fed. The sheets are connected to form a first vertical curtain. The curtain is overlapped on the side walls. Both parts surrounding the cargo or halves of the curtain are welded to each other on the side wall, in particular on its rear side. At the second stage from the top and bottom of the cargo a vertically oriented sheet is fed. The sheets are connected to form a second curtain. The second curtain is overlapped on the front side wall, on the upper and lower sides and the rear side of the side wall. Both parts surrounding the cargo or halves of the curtain are welded to each other on the side of the cargo, in particular, on the rear side of the side wall.
