Abstract

A plastic bag, made of plastic foil, has a folded-up bottom of hexagonal shape which has been formed by folding the flaps inwards crosswise. This bottom is reinforced by a top sheet which is bonded to the bottom by adhesive over the area marked with crosses. At least one of the two ends of the top sheet has an additional adhesive area in the shape of the extended section.
