The packed flexible material fabricated bags have, to be able to easily extract its content, an opening slit zone in weakening point form, with a separation cut or a perforation in the material packed. In order that the packet remains closed until the content is desired to be consumed, the packed material is re-covered at least with a mass forming film at least in the weakening point zone. The mass forming film can be, for example, the decorative printing of the bag. After the packed operation the content remains protected by the bag and for the extraction of the content the bag can be easily opened through a traction movement or folding, with which the mass forming recovering film is broken.
