1. A method for producing a portion unit of a detergent, comprising the following steps:
inserting a base element made from a first water-soluble film portion into a deep-drawing mold so as to form a holding volume from the first water-soluble film portion, the holding volume comprising a plurality of chambers which are spaced apart from one another;
pouring at least one detergent composition into the chambers;
placing a cover element made from a second water-soluble film portion onto the filled chambers;
connecting the cover element to the base element, thus enclosing the chambers, so as to form a film wrapping, sealing seams being formed between adjacent wall portions of the chambers;
removing the portion unit from the deep-drawing mold,
wherein the outside of the film wrapping is then wetted at least in the region of the adjacent wall portions and, by pressure being exerted, the sealing seams are compressed and the adjacent wall portions are brought into contact with one another and interconnected.
