The invention relates to a method for the portioned packaging of a food mass that is at least substantially incompressible, in particular of processed cheese, and that is filled as a flowable mass into a tubular sleeve comprising a thermoplastic plastic film, wherein the thermoplastic plastic film of the sleeve enclosing the food mass is deformed in a mold into individual units each defining a portion by forcing the food mass out of sealing areas, such that the units arranged one behind the other are delimited with respect to each other by means of sealing in the sealing area and are subsequently separated from one another.
