Definitions

  • the present invention relates to flexible plastic packaging containers.
  • Plastic packaging is characterized by being lightweight, stable, relatively tight, in particular water and airtight, while cost are. You will therefore find extensive use in the packaging of free-flowing solids in very many areas, such as at in the chemical Industry (granules, etc.), in the garden (potting soil, fertilizer) and in the garden The food industry.
  • FFS hoses are preferred. With these will the packaging container from an endless film web, usually directly in front of the Filling, created. Either the endless film web is produced as a hose, or it is done by rounding and welding or gluing in the longitudinal direction First, the formation of a tube from a flat film. Of the Hose is fed to the bottling plant, where a first welding or gluing seam in the transverse direction forms the bottom and after filling the contents of the container closed at the top by a second welding or gluing seam in the transverse direction becomes.
  • Block bottom bags known to provide a valve in the bottom, through which the overpressure in the Bottling escapes.
  • Block bottom sacks and especially those with elaborate ones valve designs are for cost reasons for comparative inexpensive products such as building materials not desired.
  • EP 444 261 describes flexible packaging containers in the form of a bag or bag, where a vent through perforations in a range of Container takes place, in which this is formed in two layers. These are in the inner and the outer wall perforations provided, wherein the perforations in the outer wall have a smaller cross-sectional area should have, than those in the inner wall. The venting then takes place in that there is an overpressure between the inner and the outer wall builds up, which should allow a controlled outflow. The writing leaves It can be seen that for very fine products a filter between inner and outer wall is required to prevent leakage of the filling material. In addition, these form immediately after the escape of the overpressure superimposed perforations an inlet for air, water and other impurities.
  • a flexible packaging container Plastic in which by means of welding or adhesive seams, an area is formed, which has an inner and an outer wall, wherein in the inner wall openings are provided, which emit a gas from the Inside the container in the area between the inner and the outer Wandungs enable, and enclosing the area welding or Adhesive seams allow at least in a partial area a gas outlet.
  • packaging containers are particularly preferred in which the production is made from a flat film, so that already production reasons between the outer edges of the film web in the longitudinal direction of an overlap which serve as a region between inner and outer wall can.
  • these packaging containers is a separate training this Area not necessary.
  • the plastic film directly as hose is made, the area between inner and outer wall are formed by a separate film means Welding or adhesive bond on the packaging container forming Foil is attached.
  • weld or adhesive seam or seams in Transverse gas-permeable formed.
  • weld or adhesive seam in the longitudinal direction in total or in Partial gas-permeable form.
  • a preferred way of forming the gas permeability is to the surface of the film at the points to be joined or even in total by applying a separation medium or by corona treatment so too change that the compound has a reduced strength.
  • a separation medium or by corona treatment may be one-sided or multi-sided, full-surface or partially done.
  • Suitable media are all media that are welding or prevent the plastic film from sticking, e.g. Oils, greases, hides, varnishes, powdery solids, etc.
  • the weakened connection seam ensures a controlled gas outlet to reduce a pressure occurring during or after the filling.
  • a discharge of contents were required is not necessary because the openings in the inner wall of the dense, outer wall are covered.
  • the weakened connection seam an outlet itself of very fine Particles almost impossible. This is because that between the two only Partially firmly bonded films act on adhesion forces that have a certain Adhesion even without firm connection by welding or gluing effect. Just if by a pressure difference like that during or after bottling itself developing overpressure, the adhesion forces are overcome, which opens Seam and allows the pressure to escape.
  • a fleece insert for the retention of packaged goods which in the range between inner and outer wall could penetrate, is unnecessary. Because the Openings in the inner wall of the weakened connecting seams are spaced apart, preferably, the openings are only in the middle of the Container and the transverse seams are weakened, is an exit from Packaged goods almost impossible due to the long journey. The same Applies to possibly from the outside in the area between the inner and outer wall penetrating impurities.
  • the openings in the inner wall are preferably by needling formed perforations. But it is also possible slots or other one Provide gas passage permitting openings. Preference is given to Openings, especially for very fine contents, arranged so that a the longest way possible from the openings to the (partial) area of the Connecting seam results, which allows the gas outlet.
  • a preferred embodiment therefore has openings in the longitudinal direction are arranged centrally, and the gas outlet enabling Part area is formed in one or both transverse seams.
  • the preparation of the packaging containers according to the invention takes place in essential as well as the one not with a positive pressure vent provided containers. It is only before attaching at least one Join seam the additional step of a surface treatment necessary, through in the later production of the seam, a gas permeability same is achieved at least in some areas.
  • FIG. 1 shows a side view of an FFS packaging.
  • FIG. 2 shows a section along the line A-A in FIG. 1.
  • FIG. 1 shows an FFS hose 1, which consists of a plastic film is made by these longitudinally merged so that between the two outer edges of the film 2 and 3, a region 4 with a inner wall 5 and an outer wall 6 (see Figure 2) is formed.
  • Two weld seams 7 and 8 in the longitudinal direction fix the outer edges 2 and 3 the film with the underlying or overlying film, so that a hose is trained.
  • the packaging container is filled before filling with a Floor forming weld 9 and after filling with a weld 10th provided, which closes the packaging.
  • the outer edge 2 of the film is on the later to the interior 14 of the container. 1 side facing provided with a release varnish 11, which causes the Weld 7 allows a gas outlet. Furthermore, along the Outside edge 3 in the longitudinal direction perforations 12 and embossments 13 attached.
  • Figure 3 shows an FFS package with an alternative gas permeable Seam. Identical parts are marked with the same reference numbers.
  • FIG. 3 shows a FFS tube 1, in which instead of the release varnish a corona treated area 11 'is provided.
  • the transverse welds 9 and 10 thereby allow at the location at the area 11 ', a gas outlet at overpressure.
  • the openings are as perforations 12 only in the middle of the Sackes trained. Spacers are not provided here.
