  • the surfaces of the films, layers resp. Material layers, for example, a corona, flame, ozone or plasma treatment experienced.
  • thermoplastic material layers can be transparent, translucent or opaque.
  • the material layers, especially those on the bag In the outermost layer arranged material layers, films or layers, may have a printing.
  • foils of metal for example, steel foils and preferably aluminum foils are used.
  • the thickness of the films may, for example, be from 5 to 100 .mu.m, preferably from 7 to 45 .mu.m, in particular from 7 to 30 .mu.m.
  • Suitable films of plastics are suitably made of thermoplastics, such as polyesters, polyolefins, e.g. Polypropylene or polyethylene, or as polyamides, polyvinyl chloride, polycarbonate or cellulose-containing materials such as cellophane or paper.
  • the plastic films can be present as monofilms or film composites.
  • the thickness of the films made of plastics can be, for example, from 8 to 100 .mu.m, preferably from 12 to 35 .mu.m, and in particular from 12 to 23 .mu.m.
  • the films are used for sealing, stiffening and protecting the bag exterior.
  • Extruded or melt extruded layers may be, for example, polyolefins such as polypropylenes or polyethylenes, or hotmelts.
  • the thickness of the extrudates may, for example, be from 8 to 100 ⁇ m, preferably from 12 to 60 ⁇ m, and in particular from 12 to 50 ⁇ m.
  • the on a packaging bag inwardly facing side of the packaging film is advantageously sealable.
  • Examples of a multilayer packaging film are film composites comprising a first material layer and a second material layer.
  • the first material layer may be a film, such as a mono- or composite film, of plastics, such as polyesters, oriented polypropylenes, polyamides, polycarbonate, etc., or of cellulosic materials, such as cellophane or papers.
  • the second material layer can be, for example, a metal foil or a metal foil with a sealing layer attached to the finished packaging which points inwards, like a sealing wax or a sealable film.
  • the second material layer can be a sealable film made of thermoplastic material or an extrusion layer made of a thermoplastic material which is preferably sealable.
  • a second material layer and papers such as coated papers are used.
