Definitions

  • the invention relates to a stand-up bag made of a flexible film material, in which stand-up bag two bag wall parts are connected by two longitudinal seams extending substantially in a longitudinal direction to form a bag wall forming a tubular body, with sealing edge strips projecting from the bag wall, the tubular body being closed at the two ends, at least one end of the tubular body having a base part arranged substantially perpendicular to the longitudinal direction and serving as a standing face, and a reclosable opening being provided at at least one end of the tubular body.
  • Stand-up bags for pourable products such as, for example, coffee powder, made of a flexible film material with a flat base or an enveloped base as the standing face, and a reclosable opening in the form of a zipper opposing the standing face, are also known.
  • a substantial drawback of these stand-up bags is their low degree of rigidity, whereby the bag often no longer stands upright after removal of the filling product or has no standing ability at all.
  • a bag tube made a film material with an outlet nozzle, which can be closed by means of a folding lid, is known from EP 0 966 390 B1.
  • the tube which is provided for storage on its head has two bag wall parts, which are connected by two longitudinal seams extending in the longitudinal direction of the tube to form a bag wall forming a tubular body, with sealing edge strips projecting from the bag wall.
  • This bag tube also has relatively low rigidity and leads to a reduced standing ability with progressive removal of the filling product.
  • the invention is therefore based on the object of developing a stand-up bag of the type mentioned at the outset in such a way that a tubular body has good rigidity even with a relatively thin film material and the bag retains good standing ability during use.
  • the object is achieved according to the invention in that the sealing edge strips increase the rigidity of the tubular body.
  • the side of the flexible film material forming the inside of the bag wall can be sealable and the sealing edge strips folded onto the bag wall and/or the regions covered by the folded-on sealing edge strips can be provided with a sealable coating or with an adhesive coating.
  • the two sides of the flexible film material are preferably sealable.
  • a standing face is formed by a closure part, which is attached to one end of the tubular body, with a flange having an outlet opening and a closure lid, which can reclose the outlet opening.
  • the closure lid can be screwed onto the flange or be configured as a folding lid preferably articulated to the flange.
  • the other end of the tubular body may be closed by means of a transverse seam.
  • a base part can also be sealed in or an enveloped folding base may be provided.
  • the standing face is formed by a flat base which is produced at one end of the tubular body by folding and sealing the film material or by a sealed-in base part.
  • the other end of the tubular body may be provided with a closure part with a reclosable outlet opening.
  • the closure part may be formed by a flange having an outlet opening and a closure lid, which can reclose the outlet opening, or a zipper closure.
  • a closure part with a flange having an outlet opening and a closure lid, which can reclose the outlet opening, may also be arranged in the flat base or in the sealed-in base part, it being possible to screw the closure lid onto the flange or for it to be formed as a folding lid preferably articulated to the flange.
  • the stand-up bag according to the invention is suitable, in particular, for packaging pasty, creamy, partly solid/partly liquid, liquid and pourable filling products, in particular food.
  • the packaging materials should be suitable for machine use, i.e. suitable for use on packaging machines.
  • the flexible film material may basically have a single layer, but is multi-layer in most cases.
  • the individual material layers may be applications of varnish, foils made of metals, metallised layers or films made of plastics materials, in particular thermoplastic plastics materials or composites made of metal foils and plastics material films.
  • One or more material layers may be extruded layers or films made of thermoplastic plastics materials, optionally in the composite with films/foils made of metals or plastics materials.
  • At least one material layer may be an application of varnish, such as a clear varnish, a coloured varnish, a hot metal coating etc.
  • At least one material layer may be a metallised layer or a vacuum-deposited, ceramic thin layer.
  • Adhesives, extrusion adhesives, adhesion promoters and/or primers may be located between the individual layers.
  • the surfaces of the metal layers may be subjected, for example, to a corona flame, ozone or plasma treatment.
  • the material layers which are made of thermoplastic plastics materials may be transparent, translucent or opaque.
  • the material layer, film or coating on the outside of the packaging may have printing.
  • a reverse printing or an exterior printing and a reverse printing may be applied.
  • Steel foils and preferably aluminium foils are used, for example, as foils made of metal.
  • the thickness of the foils may, for example, be 5 to 100 ⁇ m, preferably 8 to 30 ⁇ m.
  • Suitable films which are made of plastics materials are expediently made of thermoplastic plastics materials, such as polyester, polyolefins, such as polypropylenes or polyethylenes, polyamides, polyvinylchloride, polycarbonate etc or of cellulose-containing materials, such as cellophane.
  • the films which are made of plastics material may be present as monofilms or film composites.
  • the thickness of the films which are made of plastics materials may, for example, be 8 to 100 ⁇ m, preferably 12 to 30 ⁇ m and, in particular, 12 to 23 ⁇ m.
  • Extruded layers may, for example, be made of polyolefins, such as polypropylenes or polyethylenes.
  • the thickness of the extrusion layers may, for example, be 8 to 100 ⁇ m, preferably 12 to 30 ⁇ m and, in particular, 12 to 23 ⁇ m.
  • the side of the film material which is on the inside of the packaging is preferably sealable.
  • the outer side of the composite material is expediently also sealable.
  • a flexible film material examples are composites made of at least two material layers.
  • a first material layer may be a film, such as a monofilm or composite film, made of thermoplastic plastics materials, such as polyester, polyolefins, such as polypropylenes or polyethylenes, polyamides, polyvinylchloride, polycarbonate etc., or made of cellulose-containing materials, such as cellophane or papers.
  • the film may be printed on the side pointing outwardly on the finished packaging and/or be reverse-printed and is preferably provided with a sealable layer, such as, for example, a sealing varnish.
  • the second material layer may, for example, be a metal foil or a metal foil with a sealing layer or a sealable foil attached on the side pointing inwardly on the finished packaging.
  • the second material layer may, in another embodiment, be a sealable film made of a thermoplastic plastics material or an extrusion layer made of a thermoplastic plastics material, which is preferably sealable.
  • papers for example coated papers may also be used as the second material layer.
  • varnish layers or varnish applications can also be used as the second material layer.
  • the varnishes may be clear, opaque and colourless or coloured.
  • the composite material may have barrier properties against the passage of liquids, gases, vapours, steam, flavours or odorous materials.
  • metal foils for example made of aluminium
  • ceramic thin layers for example made of silicon oxides and/or aluminium oxide, which are applied by sputtering or by vacuum deposition
  • plastics materials for example, made of materials from the series of styrene copolymers, ethyl-vinyl-alcohol polymers or polyvinylidene chloride
  • sealable materials for the films or extrudates are polyolefins, such as polyethylenes, polypropylenes or co- and terpolymers of ethylene with acrylic acid. The sealability of the film material can also be achieved by an application of a sealing varnish.
  • the stand-up bags are generally smoothed out, after removal of the product, against the standing face. It is also conceivable for the bag to be rolled up from its end. For the latter case, the selection of a film material with dead-fold properties is advantageous.
  • FIG. 1 shows a side view of a first embodiment of a stand-up bag with a folding lid
  • FIG. 2 shows a side view of a second embodiment of a stand-up bag with a sealed-in base part and zipper closure;
  • FIG. 3 shows a section through the stand-up bag of FIG. 1 and FIG. 2 along the line I-I;
