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 being attached to part of a circumferential edge of the material section with a permanent fastening seam on one of the front walls and a tear line in the form of a tear line adjacent to the fastening seam Has material weakening.
  • the film bag is designed in particular as a film packaging bag and can, for example, be provided with a standing base for holding liquids such as detergents, cleaning agents, liquid soap, shampoo, shower gel, conditioner or the like.
  • liquids such as detergents, cleaning agents, liquid soap, shampoo, shower gel, conditioner or the like.
  • other packaging purposes can also be considered, for which foil bags are used in a known manner.
  • 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) 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 characterized by a particularly high-quality appearance and good functional properties.
  • sorted plastic recycling is not possible, which is why appropriate film packaging bags are usually disposed of as disposable items after use or, at best, incinerated, with at least thermal recycling being possible.
  • JPH 5-84640 U a film 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.
  • multilayer 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 thereby produced, 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.
  • FIG 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 fastened there 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 largest part of the printed material section can be torn off along weakening lines, which run directly adjacent to the sealing seams on the longitudinal edges, for optimized recycling. Narrow edges of the material section only remain directly at the heat-sealed seams. If the material section is deliberately not printed there, the bag body remaining after the material section has been torn off is completely unprinted. Simple recycling is then possible, particularly in the case of a single-variety configuration.
  • the present invention is based on the object of improving the possibilities for use and design of the film bag without impairing the possibility of recycling.
  • the fastening seam extends over a proportion between 40% and 98% of the circumferential edge. While according to EP 3 168 169 A1 Starting from a rectangular shape of the material section in the manner of a banderole, there is deliberately only fastening on the narrow sides of the banderole, the fastening seam according to the present invention extends over a proportion between 40% and 98% of the edge, so that overall a better and more complete fastening of the material section takes place on the associated front wall.
  • the present invention is based on the knowledge that the strength according to the embodiment known from the prior art is sufficient per se, but on the long sides of the material section in the manner of a banderole over a large unconnected length between the material section and the associated front wall the entire width of the foil pouch is present.
  • the material section can stand out far from the underlying front wall due to the great unconnected length. This applies, for example, when the film bag has greater mobility after partial removal of the filling material and, in particular, the bag body is no longer filled to the full.
  • the optical impairments that then result are avoided within the scope of the invention by the greater proportion of the fastening seam along the circumferential edge.
  • the fastening seam preferably extends over a proportion of at least 50% and particularly preferably of at least 60% of the circumferential edge.
  • the fastening seam preferably extends over a maximum of 90% and particularly preferably over a maximum of 85% of the circumferential edge.
  • the fastening seam and the tear line can each have a plurality of fastening seam sections or tear line sections spaced apart from one another along the circumferential edge. The proportion of the fastening seam along the circumferential edge then results together from the proportion of all fastening seam sections.
  • the tear line or tear line sections also run adjacent to the inside offset, because otherwise the desired material separation cannot be ensured when the material section is torn off.
  • the fastening seam sections are particularly preferably each designed to be continuous.
  • the fastening seam sections can in principle - similarly to a perforation as a material weakening - be designed discontinuously, with connected and unconnected areas alternating in quick succession.
  • fastening seam section always refers to a length along the circumferential edge over which a continuous tear is formed along the tear line when the material section is torn from the associated front wall. If, on the other hand, in successive connected and unconnected sections, the crack reaches the outer edge of the material section when the material section is torn off, then there is an interruption of the fastening seam there also within the meaning of the invention. As long as the tear spreads along the tear line along the fastening seam when it is torn off, it ultimately does not matter whether it is continuous or discontinuous, even if a continuous configuration is preferred in practice.
  • the fastening seam it is preferably designed as a heat-sealed seam.
  • the bag film is then expediently heat-sealable on the inside and outside of the bag, in which case the front walls and, if appropriate, folds and / or functional formations such as a pouring spout or a reclosable strip can then also be heat-sealed to form the bag body.
  • the tear line runs at a distance between 4 mm and 20 mm, preferably between 6 mm and 12 mm, to an adjacent outer edge so that the material section can be torn off as completely as possible from the assigned front wall after the foil bag has been used of the material section.
  • the distance described is selected so that the connecting seam, in particular in the form of a heat-sealed seam, can be formed between the tear line and the respectively adjacent outer edge of the material section.
  • the tear line can be formed, for example, by a perforation, a notch or by means of a laser. In the case of a perforation, severed areas and webs alternate in quick succession along the tear line.
  • the material section has a smaller thickness at the tear line. This can be achieved, for example, in that the material section is partially cut there in the thickness direction.
  • material can also be displaced, for example by means of an embossing.
  • the measures described can also be combined with a perforation.
  • weakened and non-weakened areas can alternate along the tear line. To enable particularly easy tearing
  • weakened and completely separate areas can alternate in the manner of a perforation.
  • the tear line can also be formed by means of a laser.
  • the irradiation with a laser then results in material removal and / or embrittlement.
  • the material section can also have absorbing additives so that the tear line can be formed particularly effectively without damaging the material, if necessary further layers.
  • embrittlement is also possible through the introduction of temperature.
  • the tear line can also be formed directly by the introduction of temperature and / or a displacement or displacement of material.
  • the greatest unconnected length between the material section and the associated front wall is kept small along the circumferential edge and is preferably less than 160 mm.
  • the greatest unconnected length is particularly preferably between 40 mm and 120 mm.
  • a user should be able to reach between the material section and the associated front wall at at least one point of the material section in order to be able to pull off the unconnected part of the material section from there by a tearing movement.
  • the greatest unconnected length is preferably located in an upper area of the foil bag, particularly preferably in the area of an upper corner of the bag.
  • Such an arrangement reduces the risk of accidental tearing (of "getting stuck"), with a user looking for a point of attack for tearing off the material section especially in the upper area of the bag and particularly at a corner of the bag.
  • the front walls are approximately rectangular in shape with two side edges, an upper edge and a lower edge.
  • the upper corners of the front walls can be cut off at an angle, as shown, for example, from EP 3 168 169 A1 as US 2018/0009587 A1 is known.
  • Such front walls are then also referred to as still essentially rectangular in the context of the invention.
  • the material section can be arranged in different ways on the associated front wall. In particular, it is not ruled out that the material section is arranged at a distance from the edges of the associated front wall. According to a preferred embodiment of the invention, however, the material section extends to at least one of the edges of the associated front wall.
  • the material section particularly preferably extends as far as the side edges, the lower edge and the upper edge of the associated front wall, the material section then also being fastened at least in sections to each of the edges with the fastening seam.
  • the material section is then held at all edges and thus well protected against accidental tearing off. Furthermore, the front wall is largely, almost completely or even completely covered by the material section, so that a particularly high-quality appearance results for a user, similar to a conventional film bag, which, however, cannot be recycled in the same way.
  • the fastening seam is usually also at least partially in overlap with a connecting seam at which the front walls are connected either to one another or to a fold arranged between the front walls.
  • a bottom fold can be provided between the front walls, which also forms a standing bottom.
  • the material section can also have a rectangular or essentially rectangular shape.
  • An embodiment is particularly preferred in which, starting from a rectangular shape, at least one corner is cut off at an angle. It can also be useful if the material section at the obliquely separated corner jumps back in relation to the underlying front wall. In such a set-back area, for example, the fastening seam can be interrupted along an unconnected length so that a user can intervene there to cut off the material section.
  • the set-back arrangement of the material section can also be expedient if a functional molding is provided in the area of the bag body located below.
  • a pouring spout, a handle or a reclosable strip can be considered as a functional formation.
  • a handle can be formed in different ways.
  • a handle can be formed in a particularly preferred manner simply by punching out or an incision. Such a punch-out or an incision is then expediently formed in an area which is separated from the actual receiving space of the bag body by a seal.
  • a punch-out or an incision is then expediently formed in an area which is separated from the actual receiving space of the bag body by a seal.
  • EP 3 168 169 A1 referenced.
  • both front walls are each provided with an associated material section which, with regard to the features described above, can be made the same or different without restriction.
  • the bag film can be made of a single type of polyolefin.
  • recyclates or blends containing recyclates can also be considered.
  • the bag body itself is expediently also unprinted.
  • the material section is unprinted in the area of the fastening seam and in particular outside the tear line, even if printing is not fundamentally excluded there. If the material section outside the tear line is unprinted, it is achieved that no printing ink remains due to the remnants of the material section remaining on the bag body after it has been torn off. It can particularly preferably also be provided that the material section and the bag film are made of a single type of polyolefin, a single type, unprinted residue then being present when the material section with its printed areas is separated from the bag body.
  • the material section is formed from foil.
  • other materials such as, for example, nonwoven, coated paper and a multi-layer laminate can in principle also be considered.
  • the fastening seam provided on the circumferential edge or the fastening seam sections forming the fastening seam are usually as only connection between the material section and the underlying front wall provided.
  • the material section can contribute to stabilizing the bag body in a certain way, it preferably has a significantly smaller thickness and a significantly lower weight per unit area compared to the bag film.
  • the material section can also be recycled, the resulting recyclate is of lower quality due to the residues of printing ink and the possible uses of the recyclate are also limited.
  • the weight per unit area of the material section is typically between 18 g / m 2 and 150 g / m 2 . In a preferred embodiment of the material section as a film and in the case of conventional plastics, this weight per unit area corresponds approximately to a thickness between 20 ⁇ m and 170 ⁇ m.
  • the bag film preferably has a thickness between 80 ⁇ m and 300 ⁇ m, particularly preferably between 100 ⁇ m and 250 ⁇ m.
  • the selection of a suitable thickness for the bag film also depends to a particular extent on the size of the film bag, the intended use and the loads to be expected. As the size of the foil bag increases, a greater thickness of the bag foil and possibly also of the material section must also be taken into account.
  • the material section is designed as a film, it is particularly preferably at most half the thickness of the bag film.
  • a longitudinal and a transverse direction can be assigned to the film bag according to the invention.
  • the longitudinal direction then corresponds to the course of the side edges of the front walls, the upper edge and the upper edge running along the transverse direction.
  • the material section is preferably continuously provided along its two longitudinal side edges with the fastening seam, which also extends at least in some areas on the upper edge and on the lower edge.
  • a continuous course is possible at the lower edge.
  • the material section is permanently attached to the associated front wall with the fastening seam, so that if the material section is torn off at the tear line, material separation occurs and residues of the material section remain on the front wall. It is particularly possible and in many cases preferred that the fastening seam represents the only connection between the material section and the associated front wall.
  • connection points are provided on the surface of the material section, for example so that the material section cannot lift too far from the associated front wall, which could impair the appearance.
  • connection points or connection points can be formed in different ways. While the permanent fastening seam is present along the circumferential edge of the material section, a peelable fastening can also be provided at the optionally provided additional connection points or points.
  • a peelable heat-seal seam can be produced, for example, by precisely selected sealing parameters, merely lightly tacking on and / or by arranging a lacquer that reduces the sealing strength, these variants being mentioned only as examples.
  • a permanent or peelable connection is also possible using an adhesive.
