Abstract
A sack or bag has a front wall and a rear wall which are respectively connected laterally by a lateral fold, with a strip of the front wall together with the lateral folds on at least one of the two initially open ends being folded about a first folding line running transverse to the longitudinal axis. The corresponding strip of the rear wall remains in place and the folded-over strip of the front wall, as well as the strip left in place on the rear wall, are once again folded around the outer edge of the folded-over strip and attached in this position on the outside of the sack or bag. To make a sack or bag with a tight, leak-proof bottom portion, a corner tuck each is formed on both sides between the strips of the rear wall initially left in place and the side folds folded over together with the folded strip.
