Abstract
Packaging for receiving liquid, pasty, powdery, granular or solid material having tear-open means and sealed edges and made of a foil-shaped composite material. The foil-shaped composite material has multiple layers. At least one layer of the composite material does not have weakened areas. At least one layer of the composite material has weakened areas located in the packaging at least partly in the area of the filling space. The weakened areas are preferably a series of cuts or a plurality of parallel individual cuts.
