Abstract
A bag, consisting of a single-layer or multi-layer bag wall, which is bonded to form a tube (1) and, at least at one end, has a bottom (4) which is suitable for filling with charge through a filler of a bag-filling machine, is folded and bonded and is realized with a valve opening (13), and said bag wall being designed to dissolve in a moist environment thereby releasing the charge, makes complete dissolving of the bag wall (2) possible even in the region of the bottom (4) which is provided with the valve opening (13), characterized in that the bonding of the bottom (4) is effected using a dextrin adhesive.
