Abstract
The invention concerns a multilayer sack or bag with side folds which consists of several tubular webs with side folds inserted one into the other, in which arrangement at least one open end is closed by a bottom. To form a bottom that is comparatively less thick, the outer tubular web with side folds has a projecting flap that extends over its width. At least one inner tubular web with side folds is inserted into this tubular web with side folds in such a way that it terminates at the distal edge of the flap. The projecting strip extending parallel to the flap of the at least one inner tubular web with side folds is folded over onto the outer side of the outer tubular web with side folds. The tubular webs with side folds, inserted one into the other, are folded together round the outer edge of this folded over strip and are fixed in this position.
