Definitions

  • the invention relates to a film bag with a bag body comprising at least two opposing front walls made of a bag film, wherein a printed material section is fastened to part of a peripheral 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 seam adjacent to the fastening seam Has material weakening.
  • the film bag is in particular designed as a film packaging bag and can be provided, for example, with a 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 are also possible, for which foil bags are used in a known manner.
  • a lamination composite is provided as the material for the bag wall 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 with the outer film on the inside of the contact surface is applied either 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
  • Sorted plastic waste on the other hand, can be easily recycled, but then the printing ink that is often on the bag wall, depending on the composition, can hinder the formation of high-quality recycling products.
  • JPH 5-84640 U proposes a film bag for refilling a liquid, which is provided with a peripheral separate band.
  • the film bag is stabilized by the separate, comparatively stiff band, whereby a user can also grip the film bag well.
  • multilayer film bags and film packaging are known, in which individual layers are peelable, that is, separable from one another. Fastening seams are thereby produced, the bond 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 bags and film packaging are, for example, in JPH 8-2536 A . US 2018/0009587 A1 . US 3,114,643 A and US 6,280,085 B1 described.
  • a generic foil bag is out EP 3 168 169 A1 ( Fig. 1 ) known.
  • the printed material section extends with respect to the height of the film bag only over a central area and is fastened there to permanent, ie non-peelable fastening seams in the form of heat-sealing seams on the front wall below.
  • the two mutually opposite front walls are preferably each provided with a printed material section, such an embodiment also being particularly preferred in the context 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 remain only directly at the heat seal 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 design.
  • the present invention is based on the object of improving the application and design options of the film bag without impairing the possibility of recycling.
  • the object of the invention and the solution to the problem is a film bag according to claim 1.
  • the fastening seam extends over a proportion between 40% and 98% of the peripheral edge. While according EP 3 168 169 A1 starting from a rectangular shape of the material section in the manner of a banderole, 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 on the assigned front wall.
  • the present invention is based on the knowledge that the strength according to the embodiment known from the prior art is sufficient in itself, 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 available.
  • the material section can stand out far from the front wall located thereunder due to the large unconnected length. This applies, for example, if the film bag has greater mobility after the partial removal of the contents and in particular the bag body is no longer filled to the brim.
  • the resulting visual impairments are also avoided in the context 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 peripheral edge.
  • the fastening seam preferably extends over at most 90% and particularly preferably over at most 85% of the peripheral edge.
  • the fastening seam and the tear line can each have a plurality of mutually spaced fastening seam sections or tear line sections along the circumferential edge.
  • the proportion of the fastening seam along the circumferential edge then results from the share of all fastening seam sections together.
  • the fastening seam (or the fastening seam sections) is provided along the circumferential edge of the material section, the tear line or the tear line sections runs adjacent to the inside, because otherwise the material separation desired when the material section is torn off cannot be ensured.
  • the fastening seam sections are particularly preferably each carried out continuously.
  • the fastening seam sections can in principle - similar to a perforation as material weakening - each be made discontinuously, with connected and unconnected areas alternating in short succession.
  • fastening seam section always refers to a length along the circumferential edge over which a continuous tear along the tear line is formed when the material section is torn off the associated front wall. If, on the other hand, in the case of successively connected and unconnected sections, the tear reaches the outer edge of the material section when the material section is torn off, then there is also an interruption in the fastening seam in the sense of the invention. As long as the tear spreads along the fastening seam on the tear line, it ultimately does not matter whether it is carried out continuously or discontinuously, even if in practice a continuous configuration is preferred.
  • the fastening seam is preferably designed as a heat-sealing seam.
  • the bag film is then expediently heat-sealable on the inside of the bag and on the outside of the bag, in which case the front walls and any folds and / or functional shapes, such as a spout or a resealable strip arranged between the front walls, can also be formed into the bag body by heat sealing.
  • 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 use of the film bag of the material section.
  • the distance described is selected so that the connecting seam, in particular in the form of a heat-sealing 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 perforation, severed areas and bars alternate along the tear line in quick succession.
  • the material section on the tear line has a smaller thickness. This can be achieved, for example, by partially cutting the material section there in the thickness direction.
  • material can also be displaced, for example by embossing.
  • the measures described can also be combined with a perforation. In the manner of a perforation, for example, weakened and non-weakened areas can alternate along the tear line. To make it particularly easy to tear open weakened and completely separated areas can alternate like a perforation.
  • the tear line can also be formed using a laser. Irradiation with a laser then leads to material removal and / or embrittlement.
  • the material section can also have absorbent additives, so that the tear line can be formed particularly effectively without damaging the material and possibly further layers. Embrittlement is basically also possible by entering a temperature.
  • the tear line can also be formed directly by the temperature input and / or material displacement or displacement.
  • the greatest unconnected length between the material section and the associated front wall is kept small along the peripheral 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 assigned front wall, in order to be able to pull off the unconnected part of the material section from there by a tear-off movement.
  • the greatest unconnected length is preferably in an upper area of the film bag, particularly preferably in the area of an upper corner of the bag.
  • Such an arrangement reduces the risk of accidental tearing off ("getting caught"), a user looking for a point of attack for tearing off the material section, especially in the upper region of the bag and especially at a corner of the bag.
  • the front walls In a conventional configuration, the front walls have an approximately rectangular shape with two side edges, an upper edge and a lower edge. Especially when the film bag is intended to hold liquid, the upper corners of the front walls can be cut off at an angle, as is the case, for example EP 3 168 169 A1 such 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 on the assigned front wall in different ways. In particular, it is not excluded that the material section is arranged at a distance from the edges of the assigned 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 up to the side edges, the lower edge and the upper edge of the assigned front wall, the material section then also being fastened at least in sections to the fastening seam on each of the edges.
  • the material section is then held on all edges and 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 user has a particularly high-quality appearance similar to that of a conventional film bag, but which cannot be recycled in the same way.
  • the fastening seam is usually also at least in sections overlapping with a connecting seam at which the front walls are either connected 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 stand-up base.
  • the material section can also have a rectangular or substantially rectangular shape.
  • An embodiment is particularly preferred in which, starting from a rectangular shape, at least one corner is separated obliquely. It can also make sense if the section of material springs back at the diagonally separated corner opposite the front wall below. At such a recessed area, for example, the fastening seam can be interrupted along an unconnected length so that a user can intervene there to separate the material section.
  • the recessed arrangement of the material section can also be expedient if a functional shape is provided in the area of the bag body underneath.
  • a pouring spout, a handle or a reclosable strip can be considered as the functional shape.
  • a carrying handle can be formed in different ways.
  • a carrying handle can be formed in a particularly preferred manner simply by punching out or making an incision. Such a punch-out or an incision is then expediently formed in an area which is sealed off from the actual receiving space of the bag body by a seal.
  • An example of this is the EP 3 168 169 A1 directed.
  • both front walls are each provided with an assigned material section, which can be of the same or different design without restriction with regard to the features described above.
  • foil bags should generally be designed differently on their front and back. While the product can be provided with an attractive design, a logo and legible lettering on the front, detailed information about the Ingredients, use, other properties, warnings and the like.
  • the bag film can be made of polyolefin according to type. Recyclates or blends containing recyclates can also be considered for all components of the film bag and in particular the bag film and the material section.
  • the bag body itself is expediently also unprinted.
  • the material section in the area of the fastening seam and in particular outside the tear line is unprinted, even if printing there is not fundamentally excluded. If the material section outside of the tear line is unprinted, it is achieved that no printing ink remains even after the remnants of the material section remaining after tearing off the bag body. It can particularly preferably also be provided that the material section and the bag film are made of a single type of polyolefin, with a total of pure, 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 film.
  • other materials such as nonwoven, coated paper and a multi-layer laminate can also be considered.
  • the fastening seam provided on the peripheral 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 in a certain way to stabilizing the bag body, it preferably has a significantly smaller thickness and a significantly lower weight per unit area in comparison 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 restricted.
  • the weight per unit area of the material section is typically between 18 g / m 2 and 150 g / m 2 .
  • this basis weight 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 pouch film also depends to a large extent on the size of the pouch, the intended use and the loads to be expected. With increasing size of the foil pouch, a greater thickness of the pouch foil and, if necessary, also of the material section must also be considered.
  • the material section is designed as a film, it particularly preferably has 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 provided continuously along its two longitudinal side edges with the fastening seam, which also extends at least in regions on the upper edge and on the lower edge. A continuous course is possible on the lower edge. However, it may be sufficient if only individual partial areas are fastened to the lower edge, which then each form a comparatively short fastening seam section.
  • the material section with the fastening seam is permanently fastened to the associated front wall, so that when the material section is torn off at the tear line, material separation takes place and remnants of the material section remain on the front wall. It is particularly possible and preferred in many cases that the fastening seam represents the only connection between the material section and the assigned 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 assigned 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 peripheral 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 carried out, for example, by means of precisely selected sealing parameters, only light attachment and / or the arrangement of a varnish that reduces the seal strength, these variants being only mentioned as examples.
  • a permanent or peelable connection is also possible with adhesive.
  • At least one additional connection is produced within the surface of the material section by adhesive or heat sealing, then this is expediently also surrounded by a material weakening in accordance with the weakening line along the fastening seam. If the material section is then torn off, in addition to the remnants of the material section on the fastening seam, individual “islands” also remain within the surface of the material section, which according to a preferred embodiment of the invention are then not printed, so that the remaining bag body also contains the remnants of the material section then ideally completely free of printing ink.
