ABSTRACT:
A hose-shaped bag (1) is formed of a composite foil made up of a metal foil (3c) and at least one plastic foil (3a) arranged as an outer layer on an outer surface of the metal foil (3c). A weakened location is provided in the outer plastic foil (3a) produced by a thermal heat effect and affording a rated failure location. The weakened location reduces the overall mechanical strength of the composite foil (1), so that an opening member on a dispensing tool can reliably open the hose-shaped bag at this location.
