ABSTRACT A perforation (11) is made next to at least one joining edge (42) in a basic layer (1). A plastic film (2) is then applied to at least one side of the base layer (1), covering the perforation (1). A cut-out is made from the package material (3) so obtained. The cut-out has at least one film tab which juts out next to at least one joining edge (42) and which previously formed the portion (21) of the film placed over the perforation. A joining edge (42) on the inside or outside of the package is then covered and sealed by this film tab. The basic layer is preferably paper or cardboard and can therefore be simply and attractively printed. If the basic layer (1) is enclosed between two plastic films (2), the two films can be united in all film tabs. The joining edges are then already completely enclosed on the cut-out. Very strong, flat and tightly sealed joins can be obtained. Webs, sheets or cut-outs of packaging material for finishing the package can be supplied during filling.
