  • Another Sollrissstelle is z. B. a commonly arranged in a sealed seam Anreisskerbe.
  • the invention is therefore an object of the invention to improve a bag packaging of the type mentioned in such a way that it can be easily opened by persons with limited functions of their hands and fingers.
  • the bag has a disposed within the packaging film of the bag, bounded by a line of weakness opening tongue, the opening tongue is covered by a glued or sealed against the packaging film of the bag cover strip and formed a free end of the AbdeckstMails as a tangible opening tab is, wherein the adhesive force of the adhesive or sealing compound between the cover strip and the packaging film of the bag package is greater than the separation force required for separating the opening tab from the packaging film of the bag.
  • the line of weakness can be introduced from one or both sides of the packaging film in the material, for. B. as a perforation or as a partial section line, for example as a laser or knife cut, or by punching.
  • the opening tab is configured over a large area and thus offers a good grip. Also, the opening tab as such should be immediately recognizable and marked accordingly.
  • the opening tab may additionally have a non-slip and non-slip surface.
  • the structure with height differences may consist of lying at any angle to a tearing direction, parallel grooves or intersecting or intersecting, line-shaped elevations or depressions.
  • the opening tab of the cover strip differs optically from the printed image on the bag packaging and is thus more easily recognized.
  • the cover strip should be easily peelable.
  • moisture-sensitive products may contain a desiccant or the desiccant may be in the sealant layer.
  • the packaging film used for the pouches and the cover strips is single or preferably multi-layered or multilayered.
  • the individual material layers can be lacquer applications, films made of metals, metallized layers or films made of plastics, in particular thermoplastics or composites of metal foils and plastic films.
  • One or more layers of material may be extruded, in particular melt-extruded, layers or films of thermoplastics, occasionally in combination with films of metals or plastics.
  • At least one layer of material may be a coating application, such as a clearcoat, a color finish, a hotmelt coating, etc.
  • At least one layer of material may be a metallized layer or a vacuum deposited ceramic thin film.
  • Adhesives, extrusion adhesives, adhesion promoters and / or primers can be located between the individual layers.
  • Adhesives, extrusion adhesives, adhesion promoters and / or primers can be located between the individual layers.
  • 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 layers of material in particular the layers of material, films or layers arranged on the bag in the outermost position, 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 expediently made of thermoplastics, such as polyesters, polyolefins, for example polypropylenes or polyethylenes, or 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 slides out For example, plastics may be 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 may, for example, be a metal foil or a metal foil with a sealing layer, such as a sealing lacquer or a sealable foil, applied to the side facing the finished packaging.
  • 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.
  • papers e.g. coated papers are used.
  • paint coats or paint jobs can be used as a second material layer.
  • the packaging film may have barrier properties against the passage of, for example, liquids, gases, vapors, steam, aromas or odors.
  • ethyl vinyl alcohol polymers or polyvinylidene chloride can be used as the ethyl vinyl alcohol polymers or polyvinylidene chloride.
  • sealable materials for the films or extrudates are polyolefins such as polyethylenes, polypropylenes or copolymers and terpolymers of ethylene with acrylic acid.
  • the sealability of the composite material can also be achieved by applying an aqueous, solvent-based or UV, IR or high-energy radiation-curing sealing wax.
  • the latter may be pre-marked in the form of a partial cut line, perforation or the like. Line of weakness in the packaging film, in this way to reduce the tearing resistance or to effect a controlled tearing.
  • Partial section line is to be understood as a section line which only leads through part of the film layers or individual films of the packaging film and consequently only partially penetrates the laminate.
  • a line of weakness is here a so-called Sollrissstelle in the form of a line or a limited, elongated surface section to understand, which has a significantly lower tensile strength than the rest of packaging or wall foil, and which breaks under a certain tensile load, for example, a tearing movement enough with your hands.
  • the weakening line can be produced for example by local weakening of a limited film section by means of chemical or physical or mechanical measures.
  • An in Fig. 1 Bag package 10 shown by way of example in the form of a flat bag essentially consists of two packaging films resting on one another, which form a front side 12 and a rear side 14 of the bag and are connected to one another by way of a marginal circumferential sealing seam 16.
  • an opening tab 18 bounded by a weakening line 20 inside the packaging film of the front side of the bag 12 is arranged.
  • a cover strip 22 covers on the front side 12 of the bag 10, the opening tongue 18 and extends over the side edge of the bag to the bag back page 14th
  • the cover strip 22 is sealed against the packaging film of the bag front and - back side 12, 14.
  • a free end of the cover strip 22 as a tangible opening tab 24 is not sealed against the bag wall.
  • the adhesive force of the sealing connection between the cover strip 22 and the packaging film of the bag package 10 is set so that it is higher on the one hand than the separation of the opening tab 18 along the line of weakness 20 from the opening of the packaging sheet 18 surrounding the bag front side 12 required separation force, and on the other the cover strip 22 by pulling on the opening tab 24 dissolves without too much force from the bag wall, ie, is easily peelable.
  • the opening tongue 18 is cut out of the surrounding packaging film along the line of weakness 20 and remains firmly connected to the cover strip 22.
  • the pouch 22 may be connected to the packaging film of the pouch packaging by resealing the pouch via a pressure sensitive adhesive (PSA).
  • PSA pressure sensitive adhesive
  • the weakening line 20 bounding the opening tongue 18 can be attached to the packaging film at the appropriate point during the production of the bag.
  • the cover strip 22 can be applied, for example, as an adhesive tape on the finished package, preferably in-line during bag production.
