Definitions

  • the invention relates to a film bag with a bag body made of a bag film and having at least two opposing front walls, a printed material section with a permanent, non-separable connecting seam being attached to one of the front walls and lying unconnected in some areas on the associated front wall, the material section having a smaller thickness than the bag film has.
  • the film pouch is in particular a film packaging pouch, various configurations being possible.
  • Foil packaging bags can be equipped, for example, with stand bases, side gussets, carrying handles, pouring spouts, reclosers or the like. Foil packaging bags are suitable for the provision, storage and transport of a wide variety of foods, household chemicals and other goods of daily use.
  • film packaging bags can be used for solid, lumpy, granular or powdery, as well as liquid or pasty products, which are optimally protected by the bag body.
  • Such film packaging bags are tightly or largely tightly closed after filling, so that safe transport and safe storage are then possible. If the foil pouch has a reclosure, further storage is possible even after it has been opened for the first time.
  • the material for the bag wall is often a lamination composite as a bag film with an inner film made of polyethylene (PE) and an outer film based on polyethylene terephthalate (PET) or biaxially oriented polypropylene (BO-PP), with a printing layer in front of such a lamination composite Gluing the inner film to the outer film on the inside at the contact surface is either applied to the outer film or the inner film and is then visible through the transparent outer film.
  • PE polyethylene
  • PET polyethylene terephthalate
  • BO-PP biaxially oriented polypropylene
  • Such conventional film packaging bags are distinguished by a particularly high quality appearance and good functional properties.
  • due to the lamination of the different polymer materials single-type plastic recycling is not possible, which is why corresponding film packaging bags are usually disposed of as disposable items after use or, at best, incinerated, with at least thermal recycling still possible.
  • JPH 5-84640 U a foil bag for refilling a liquid is proposed, which is provided with a separate circumferential band.
  • the foil pouch is stabilized by the separate, comparatively stiff band, whereby a user can also easily grip the foil pouch on the band.
  • multi-layer film bags and film packaging are known in which individual layers can be peeled off, that is to say are connected separably from one another. Fastening seams are produced in this case, the composite adhesion of which is set such that these fastening seams are separated when a tensile force is exerted on the contact surface of the successive layers.
  • Various embodiments of such film pouches and film packaging are for example in JPH 8-2536 A , US 2018/0009587 A1 , U.S. 3,114,643 A and US 6,280,085 B1 described.
  • a film bag of the generic type is out EP 3 168 169 A1 ( Fig. 1 ) known.
  • the printed material section extends only over a central area and is there attached to permanent, ie non-peelable fastening seams in the form of heat-sealed seams on the underlying front wall.
  • the two opposite front walls are preferably each provided with a printed material section, such a configuration also being particularly preferred within the scope of the present invention.
  • the present invention is based on the object of specifying a film bag which has a high-quality appearance, has good functional properties and enables improved recycling.
  • the material section to extend over at least 80% of the area of the associated front wall and for the connecting seam to run around an edge of the material section in a closed frame-like manner.
  • a continuous connecting seam is thus provided that cannot be separated.
  • the printed material section is thus securely held during the transport, storage and use of the film bag.
  • the continuous connection seam which is closed in the form of a frame, also avoids or at least significantly reduces the risk of contamination between the material section and the associated front wall. This applies even if, according to a variant described in more detail below, the material section has an opening within the frame-like closed connecting seam, because in typical applications during storage, transport and also use of the film bag, the edge areas are exposed to a greater risk of contamination.
  • the material section is fastened to the associated front wall by the frame-shaped closed, continuous connecting seam, the bag film on the one hand and at least part of the material section can be recycled separately from one another after use of the film bag by suitable measures.
  • the material section within the connecting seam is essentially unconnected to the associated front wall.
  • the foil bag After the foil bag has been crushed, at least Separate particles of the bag film on the one hand and of the material section on the other hand are formed for the unconnected areas. A separation is then possible with technical means. For example, optical devices can be used to determine whether the individual particles are provided with a print, so that suitable sorting is possible on this basis.
  • Sorting can also take place, for example, by air sifting if the bag film on the one hand and the material section on the other hand have a sufficiently different thickness with a comparable density of the materials used in each case.
  • the density is, for example, in a range between 0.9 g / cm 3 and 1 g / cm 3 , for example between 0.92 g / cm 3 and 0.97 g / cm 3 . If particles with the same area are then cut from the bag film on the one hand and the printed material section on the other hand, the weight of the different particles essentially depends on the thickness for a comparable density of the materials. The different particles can then be separated from one another by air classification.
  • the thickness ratio of the bag film to the material section is at least 3: 2, a thickness ratio between 2: 1 and 6: 1 being particularly preferred from a practical point of view.
  • the bag film is expediently unprinted. If, however, within the scope of the measures described above, particles are separated by optical means after shredding the film bag, printed parts of the bag film could also be sorted out, so that a reliable division into a high-quality and a less high-quality particle fraction can then also take place. However, the disadvantage would then arise that with the printed sections of the bag film, due to the greater thickness, a relatively large amount of material is assigned to the less valuable fraction.
  • the bag film could be printed with a printing ink that is, for example, water-soluble.
  • a printing ink that is, for example, water-soluble.
  • the bag film is initially well protected against environmental influences by the material section arranged on it.
  • only small areas of the bag film are provided with an imprint which does not lead to any significant impairment of the corresponding particle fraction.
  • very small imprints in the sense of positioning marks or the like can be useful for the manufacturing process without the corresponding recycling material being unduly impaired.
  • a mechanical division between the bag film and the material section can take place in the course of a recycling process. Additionally or alternatively, however, it is also advantageous if already manually, in particular by a user after the film bag has been emptied, a separation can take place. It should be noted that the users are increasingly willing to behave in a responsible and environmentally friendly manner, with corresponding products being viewed as advantageous.
  • the material section adjacent to the fastening seam has a weakened area in order to be able to separate a frame attached to the connecting seam from a center piece of the material section by separating the material within the material section. It is thus possible for a user after the use of the film bag to consciously tear off the middle piece from the bag body, so that separate sorting and disposal is possible from the outset.
  • the material section is only printed on the center piece, so that the frame remaining on the associated front wall is then unprinted along the connecting seam.
  • the entire remaining bag body is then not provided with printing ink and can be used as a particularly high-quality recycling product.
  • single-type is understood in particular when the various components are made, for example, of matching polyethylene or matching polypropylene, whereby polyethylene or polypropylene of different densities such as ULDPE, LDPE, LLDPE, MDPE, LMDPE, HDPE can be recycled together as a mixture .
  • polyethylene or polypropylene of different densities such as ULDPE, LDPE, LLDPE, MDPE, LMDPE, HDPE can be recycled together as a mixture .
  • ULDPE LDPE
  • LLDPE low density polypropylene
  • MDPE low density polyethylene
  • LMDPE low density polyethylene
  • the middle piece can be torn out by a user, various facilitating measures can be provided for this purpose.
  • the weakened area has a weakened line or is formed by a weakened line.
  • a weakening can initially result from the fact that the polymer material of the material section is weakened solely due to the formation of the connecting seam. This is particularly true if the connecting seam is formed as a heat-sealed seam according to a preferred embodiment of the invention.
  • a weakening of the sealing jaws can result adjacent to the heat sealing seam solely due to the action of temperature and also the mechanical loading of the sealing jaws.
  • a low strength is often observed at the seam root, that is to say at the lateral edge of such a heat-sealed seam.
  • a line of weakness can also be deliberately formed. This can be, without restriction, a perforation, an impression, or a section of material a not completely cutting incision, a laser line or the like.
  • the polymer structure of the material can be weakened and / or partially cut or removed by a laser.
  • an engagement opening in the material section can additionally or alternatively also be provided within the frame.
  • a region of the material section lying within the frame can be punched out.
  • Such an engagement opening can, for example, be so large that a finger can be inserted there by a user. If a user then engages in this engagement opening, the middle piece can easily be torn off.
  • the engagement opening is expediently arranged adjacent to the connecting seam, in particular in a corner region. Since the engagement opening is not located directly on the edge of the front wall, but is arranged within the frame, good protection against accidental tearing is achieved.
  • a separate tear-off tab can be attached to the material section within the frame.
  • the tear-off tab can be formed, for example, by a film strip which is firmly glued or sealed onto the material section at one end and which can be gripped by a user at its other end.
  • Corresponding tear-off tabs are known from the packaging sector, for example from packaging for handkerchiefs.
  • the bag film is essential for the structural stability and shape of the bag body, while the printed material section essentially serves as a type of information carrier and is not essential to it must contribute to stabilization.
  • the printed material section can thus be made comparatively thin, the thickness being, for example, between 10 ⁇ m and 80 ⁇ m, in particular between 20 ⁇ m and 50 ⁇ m.
  • the material section is formed in one layer from a monofilm, which can then be printed on the inside in the direction of the associated front wall or also on the outside.
  • the film forming the material section or at least one layer of such a film can be monoaxially or biaxially oriented.
  • an at least two-layer structure of the material section with a sealing layer and an outer layer is also possible.
  • the sealing layer and the outer layer can also be made of a single type, for example from polyethylene or polypropylene, although different types or blends can be used with regard to the different requirements. If, for example, the sealing layer has a low melting or softening point compared to the outer layer, the appearance of the film bag on the outside at a suitable sealing temperature is not impaired by the sealing seam.
  • the material section can also have an internal print which is arranged between the sealing layer and the outer layer at an internal transition.
  • further layers can also be provided.
  • the sealing layer and the outer layer are unconnected or peelably connected in an edge section arranged above a section of the connecting seam, the sealing layer and the outer layer being permanently connected in this way, optionally with the incorporation of further layers adjacent to the edge section that when the middle piece of the material section is torn off from the associated front wall, starting from the edge section, the sealing layer tears and thus a layer separation at the permanent connection is avoided.
  • the material section and the associated front wall are connected to one another exclusively at the connecting seam.
  • the entire area of the material section lying within the connection seam can then be easily separated by tearing off or comminuting.
  • individual connection points are also provided for stabilization within the circumferentially closed connection seam.
  • connection points are formed, for example, by heat sealing, these can be made permanent or peelable without restriction.
  • a permanent connection as well as on the connection seam itself, can then be easily produced.
  • the imprint of the material section is expediently also left out at such connection points so that no undesired paint residues remain on the bag film or are connected to the bag film.
  • the connecting seam is preferably designed as a heat-sealed seam.
  • the typical width of the connecting seam is between 1.5 mm and 10 mm, in particular between 2 mm and 8 mm.
  • the bag film is made of one type of polyolefin, although thin functional and barrier layers are also possible. It is particularly preferred that the bag film and the material section are made of single-type polyolefin, for example made of single-type polyethylene or single-type of polypropylene.
  • the thickness of the bag film is typically between 50 ⁇ m and 300 ⁇ m, preferably between 80 ⁇ m and 170 ⁇ m.
  • the material section extends only over a partial area of the front wall and is fastened there in the manner described in the form of a frame with the continuous connecting seam.
  • the material section particularly preferably extends over the entire assigned front wall or essentially over the entire assigned front wall, so that overall a double-walled design results.
  • both front walls can also be provided with an associated material section in the manner described, so that the film bag according to the invention cannot then, at least at first glance, be differentiated from a conventional film bag.
  • the bag film is preferably unprinted.
  • the bag film itself can be largely clear, opaque or also non-transparent, in particular colored white.
  • Many plastic materials are clear or opaque in their pure form, so that this appearance results without the addition of additives.
  • a colorant that is harmless for many applications such as titanium dioxide
  • Such a white batch is also uncritical with regard to recycling, in particular if the crude product to be formed during the recycling itself is to be uniformly colored, with color particles such as titanium dioxide being regularly used for this purpose.
  • the foil pouch can also have functional elements such as, for example, pressure closures (zippers), zippers (sliders) or also pouring spouts.
  • functional elements such as, for example, pressure closures (zippers), zippers (sliders) or also pouring spouts.
  • Corresponding functional elements can be used without can also be made of the same material as the bag film, so that this then does not hinder recycling.
  • the film pouch comprises the pouch film on the one hand and the printed, frame-shaped attached material section on the other hand on at least one front wall formed from the pouch film.
  • the material section is usually also formed from a conventional film.
  • the separately manufactured and provided bag film on the one hand and the film for forming the material section on the other hand can then be fed and handled differently.
  • the bag film and the film can run separately to form the material section and for a connection to take place only when the actual bag body is formed by heat sealing.
  • the bag body can be formed from a single material blank of the bag film or also from several sections of the bag film. If the foil pouch has side gussets, these side gussets can either be inserted from a single material blank by folding or provided as separate strips when several sections are joined together.
  • the bag film and a film for forming the material section can have longitudinal strips of adhesive be connected, in which case a connection by adhesive or a connection by heat sealing is also possible in the transverse direction, depending on the process control.
  • the connecting seam is also possible for the connecting seam to be formed in different ways on different sections. It is only essential to the invention that the connecting seam runs around the edge of the material section in a permanent, non-separable manner and generally closed in a frame-like manner.
  • FIGS. 1A and 1B show a film pouch with a pouch body 2 made of a pouch film and having two opposite front walls 1, with an associated printed material section 3 with a permanent, non-separable connecting seam 4, in the form of a frame-shaped closed heat-sealed seam being attached to each front wall 1.
  • the area of the material section 3 within the connecting seam 4 is not connected to the associated front wall 1.
  • the material section 3 has a smaller thickness than the bag film, that is to say the associated front wall 1.
  • the material sections 3 extend over the entire surface of the respectively assigned front wall 1, so that according to FIG Figure 1B a kind of double-walled construction results.
  • the material sections 3 are each provided with an imprint 7 only in a central piece 6 surrounded by a weakening line 5.
  • the front walls 1 and a frame 8 of the material section 3 that runs around the center piece 6 and with which the material section 3 is attached to the connecting seam 4 are completely unprinted.
  • the bag body 2 having the front walls 1 and the material sections 3 are made of one type of polyolefin, for example one type of polyethylene or one type of polypropylene, but different types or blends are possible.
  • the bag film which forms the front walls 1, made of polyethylene with a thickness of 100 ⁇ m, while the material sections are each formed from a polyethylene (MDO-PE) oriented in a machine direction with a thickness of 25 ⁇ m.
  • MDO-PE polyethylene
  • the material sections 3 are expediently according to FIG Figure 1B printed on their side facing the respective front wall 1, so that the imprint 7 is well protected.
  • the particles formed from the bag film on the one hand and the material section 3 on the other hand can thus be easily and reliably separated from one another.
  • a third particle fraction is to be taken into account, in which in areas of the connecting seam 4 according to FIG Figures 1A and 1B the material section 3 is connected to the respectively assigned front wall 1. These particles are also comparatively heavy and can be separated together with the particles of the bag film. Since this third particle fraction is also not provided with an imprint according to a preferred embodiment of the invention, overall very good recycling is possible.
  • the proportion of high-quality, unprinted recyclate is at least 80%.
  • the previously described weakening line 5 is provided, which can be designed as a notch, perforation or laser seam.
  • a notch is shown as an example in this context. In this context, it should be pointed out that such a separately formed weakening line 5 is not absolutely necessary, depending on the configuration.
  • a weakened area can also arise from the fact that, due to the creation of the connecting seam 4, the polymer material at the edge of the connecting seam 4 has a reduced strength due to the action of pressure and temperature.
  • an engagement opening 9 is provided within the frame 8. Specifically, the engagement opening 9 is provided in the area of a corner of the bag. The engagement opening 9 is selected to be so large that a user can insert a finger there and subsequently tear out the center piece 6, whereby all of the printed material is removed from the bag body 2.
  • the Fig. 2 5 shows an alternative embodiment based on this, with a separate tear-off tab 10 being attached to the material section 3 within the frame 8.
  • One end of the tear-off tab 10 is firmly glued or sealed to the material section 3, and the other end of the tear-off tab 10 can be gripped with a finger so that the middle piece 6 can then be removed by pulling on the tear-off tab 10.
  • the film bag has only two front walls 1 which are directly connected to one another.
  • a foil bag in the form of a gusset bag is shown as an example. Additional side folds 11 also run between the two front walls 1, an internal functional element 12 in the form of a reclosure also being indicated in a head region of the bag body 2.

  • the imprint 7 can also be arranged on the inside between the sealing layer 14 and the outer layer 15, so that optimal protection results.
  • the sealing layer 14 and the outer layer 15 are in the area above a section of the connecting seam 5 arranged edge sub-section 13 unconnected or peelable, i.e.
  • the sealing layer 14 and the outer layer 15 adjacent to the edge sub-section 13 being permanently connected to one another in such a way that when the middle piece 6 of the material section 3 is torn off from the associated front wall 1 starting from the edge sub-section 13 tears the sealing layer 14 and thus a separation of the layers at the permanent connection of the sealing layer 14 and the outer layer 15 in the area of the middle piece 6 is prevented.
  • a release layer can be provided on the edge section 13, for example, before a lamination adhesive is applied. In order to avoid a connection, the laminating adhesive can also be left out there.
  • the bond strength between the sealing layer 14 and the outer layer 15 is thus greater than the strength of the sealing layer 14 along the thickness, for which in principle weakening lines (not shown) can also be provided.
  • a controlled cohesive break is achieved within the sealing layer 14 and an adhesion break between the sealing layer 14 and the outer layer 15 or a layer of laminating adhesive provided there is avoided at the center piece 6.
  • the printed film material of the material section 3 can therefore be separated from the unprinted bag body.
  • the width of the connecting seam 4 is usually between 2 mm and 8 mm.
