Definitions

  • the invention relates to a gusseted bag, in particular a prefabricated, unfilled gusseted bag, with two front walls and two gussets, which connect in each case via side edges to the front walls and centrally between the respective side edges have a running in a bag longitudinal direction of bending line, wherein at one of the gussets on a Bag side outside a carrying handle assembly, which has a handle film attached, and wherein the handle assembly as seen in the longitudinal direction is fixed to end portions and between the end portions has a handle portion extending in the transverse direction, ie perpendicular to the longitudinal direction over less than 80% of the width of the associated Gusset extends and each has a distance of at least 5 mm to the two associated side edges.
  • the invention also provides a method for producing such a gusseted bag.
  • Side gusset bags are used in various sizes for packaging purposes and are useful, for example, in the packaging of bulk materials such as animal dry foods, detergents, cat litter, road salt, and powdery or grainy construction materials.
  • gusseted bags are also provided with a reclosing device to allow for a first-time opening and the removal of a subset of some protection.
  • Such reclosure is usually located on a bag head or at least an upper portion of the gusseted bag and may extend only over a portion, such as a gusset, or the entire width.
  • the reclosure may, for example, as So-called zipper or slider closure are executed, the strip-shaped tongue and groove elements, which can be closed manually by pressure or a slider closure by a tab in the manner of a zipper in a zipper closure and opened by an opposite application of force.
  • Other re-closures such. As Velcro or self-adhesive strips come into consideration.
  • the entire gusseted bag can be formed by folding from a single sheet of film.
  • both individual prefabricated and not closed at least one side gusseted bag can be formed, which are initially stored and transported and then filled and sealed subsequently.
  • prefabricated bags pre-made bags
  • the prefabricated gusseted bags are opened and then filled through a hopper before these gusseted bags are sealed by welding, gluing and / or turning over the open section.
  • the closed gusseted bag usually ensures a tight storage of the contents.
  • individual bags can also be formed directly in the filling process in a so-called FFS (form fill and seal) process.
  • FFS form fill and seal
  • a film tube is produced with gussets directly around a hopper, which is then immediately closed after filling, with individual filled bags are separated from the strand.
  • the present invention also relates to embodiments wherein the front walls and gussets are formed from separate pieces of a bag film.
  • the EP 1 541 332 A1 describes such a method for the production of gusseted bags, in which a bag string is formed such that successive gusseted bags are arranged side by side with their bag longitudinal edges.
  • the production direction thus corresponds to a bag transverse direction of the individual gusseted bags.
  • a bag string is formed with successive, initially connected bag blanks.
  • a first film web is guided in the production direction.
  • a film strip is fed, wherein the edges of the film strip are folded over to a central portion.
  • the edges are usually the same width, leaving a gap between the two edges after folding.
  • pieces of film strip at a uniform distance transversely to the production direction are placed on the first film web before a second film web is fed in the production direction, with the first film web and the pieces of film strips are covered.
  • longitudinal sealing seams are produced transversely to the direction of production, with which the film strips are welded on the one hand to the folded edges with the second film web and on the other hand on its opposite side with the first film web.
  • individual side gusset bags are separated from the thus formed bag strand by a cut in the region of the film strips in such a way that two gussets of successive gusseted bags are formed from a folded film strip.
  • the method described is also referred to in practice as a transverse method or Totani method. Regardless of the method of manufacturing the gusseted bag, there is often a need to provide the gusset bag with a handle assembly, such a handle assembly being disposed either on a bag head or on one of the two gussets.
  • the present invention relates to a gusseted bag having a handle assembly attached to the outside of the bag at one of the two gussets, the handle assembly having a handle film and secured to end portions in the longitudinal direction with a handle portion between the end portions. A user's hand may then be made between the handle portion and the underlying gusset.
  • the entire handle assembly extends in the transverse direction, ie perpendicular to the longitudinal direction, over less than 80%, preferably less than 60% of the width of the associated gusset between the side edges, wherein the handle assembly also at the two associated side edges each at a distance of at least 5 mm , preferably at least 15 mm.
  • a generic gusseted bag is made WO 2009/095806 A2 known, for easier folding of the side edge in the region of the handle assembly, a line of weakness in the handle sheet can be provided. Especially with a thick handle film but still remains a significant spreading tendency.
  • the EP 2 354 026 B1 discloses a carrying handle assembly with two loop handles, each located in the region of a side edge. Even if a particularly comfortable handling is possible by the described embodiment with two loop handles, a relatively complex production must be accepted.
  • the present invention seeks to provide a gusseted bag with a mounted on the outside of a gusset handle assembly, which has a lower tendency to spread on the corresponding gusset. Furthermore, a method for producing such a gusseted bag should also be specified.
  • the invention and solution of the problem are a gusseted bag according to claim 1 and a method for producing a two front walls and two gussets of a bag film having gusseted bag according to claim 16.
  • the carrying handle film is interrupted at the bend line by a longitudinal gap with a width of at least 2 mm, which separates the handle film into a first handle film section and a separate second handle film section.
  • a longitudinal gap with a width of at least 2 mm, which separates the handle film into a first handle film section and a separate second handle film section.
  • the width of the gap is at least 2 mm, so that air also remains directly at the bend line in order to easily transfer the corresponding gusset to itself there.
  • the gap also allows that in the production of the gusseted bag, the bending line by a folding knife or the like is formed only when the two handle film sections are already applied. Exactly along the crease line remains namely a free of the handle film area, which can be easily manipulated and folded.
  • the gap extends straight over its entire length and also has a same width.
  • the gap is chosen so that the Aufsp Son effect on the associated side edge is minimized, on the other hand, the two handle film sections can easily be penetrated by a user as a common carrying handle.
  • the gap has a width of at least 2 mm, preferably at least 5 mm.
  • the gap is expediently less than 20 mm, preferably less than 15 mm.
  • a suitable gap is, for example, 10 mm.
  • the gusseted bag is preferably formed as a prefabricated, flattened package which is closed at one longitudinal end and unclosed at the opposite longitudinal end for subsequent filling. Especially with such a prefabricated gusseted bag (pre-made bag) is a good shelf life and ease of use in still unfilled state of importance.
  • the first carrier film section and the second carrier film section are arranged mirror-symmetrically with respect to the crease line.
  • the handle assembly has a widening in the transverse direction at the end portions relative to the handle portion, wherein the two handle film segments then starting from the gap in the direction of each adjacent side edge have a C-shape. Apart from the central gap between the two handle film sections thus results in a shape that is pronounced of the stylistic representation of a dog bone.
  • the two carrying handle film sections are connected to one another exclusively via the associated, associated side fold.
  • the two carrying handle film sections are connected by an applicator film, the applicator film however being thin in comparison to the carrying handle film.
  • the ratio of the thickness of the handle film to the thickness of the application film is correspondingly at least 3: 1.
  • the handle film usually has a thickness between 150 microns and 400 .mu.m, in particular between 200 .mu.m and 300 .mu.m
  • the Applizierfolie can easily be performed with a thickness of less than 100 .mu.m, in particular less than 50 microns.
  • the Applizierfolie essentially serves a good handling of the handle film sections in the production and does not absorb large weight or tensile forces.
  • the carrying handle assembly a for the user known and apparently one-piece shape, so that a user will always engage behind both carrying handle film sections as a handle loop.
  • the gusseted bag can be formed from a material web or a film blank by folding.
  • pieces of a bag film for forming the two front walls and the two side folds are fed separately, in particular with the cross-method described above, and then connected to form a bag body.
  • a multilayer bag film is generally provided, which is heat-sealable on the inside and which has a high-quality outer layer.
  • film laminates are often used with an internal imprint, such a laminated composite often having an outer film of polyethylene terephthalate (PET) or biaxially oriented polypropylene (BO-PP), while the inner surface formed by an inner film of the bag film made of polyethylene (PE) ,
  • PET polyethylene terephthalate
  • BO-PP biaxially oriented polypropylene
  • the carrying handle assembly is preferably adhered to the end portions.
  • Particularly suitable are handle assemblies that are self-adhesive and consequently only need to be placed on the respective gussets and optionally still be pressed. If the gusseted bag is also heat-sealable on the outside of the corresponding gusset, a fastening by heat-sealing may also be carried out in principle.
  • the front walls and / or the side folds of the gusseted bag may comprise a layer of a plastic ribbon fabric.
  • the bag body is relatively strong and difficult to handle, so that then spreading in the handle assembly can have a very adverse effect.
  • the gussets may extend in the longitudinal direction over the same height as the two front walls or offset from the front walls. Side gussets offset from a bag head result in particular in a transverse process. In contrast, when the gussets are formed solely by folding from a bag string, gussets can be shortened by punching. Corresponding measures are for example EP 1 754 596 B1 known.
  • the side edges are also provided with a longitudinal sealing seam. While side gusseted bags made in a transverse process require such longitudinal sealing seams to close the formed bag body in the circumferential direction, corresponding longitudinal sealing seams for stiffening are also useful in a gusseted bag formed by folding a material web or a film blank.
  • the entire handle assembly extends over less than 60% of the width of the associated gusset, with respect to the respective adjacent side edges also remains a distance of at least 15 mm. Accordingly, in the manufacturing process, the side edges and possibly also longitudinal sealing seams can easily be formed without the carrying handle arrangement being an impairment, even if this is already applied during the folding of the film and / or during the production of longitudinal sealing seams.
  • the invention also provides a method for producing a side-folding bag having two front walls and two side-folds from a bag film, in particular the side-folding bag described above.
  • a bag handle portion forming a first gusset portion has a carrying handle assembly having a handle film placed such that a gap having a width of at least 2 mm extending between two handle film portions of the handle film extends along a center line of the corresponding first gusset.
  • a crease line is formed along the centerline of the first gusset and a centerline of the second gusset, and further, by folding the bag film and / or joining a plurality of pieces of the bag film, a bag body is formed such that the two gussets are self-adhering to each other folded and inserted between the front walls.
  • said steps are carried out in the described series film.
  • the handle assembly is preferably applied to the still flat, unfolded bag film section before it is folded to the shape of the gusset. Just here it is of particular advantage that the relatively thick and stiff handle bar film can not be transferred.
  • the two Carrier film sections can be supplied separately from each other and attached to the associated bag film section.
  • the two carrying handle film sections are supplied together with an application film wherein, after the attachment of the handle film sections to the associated bag film section, the applier film is withdrawn from the handle film sections.
  • the tote film sections may then be fed onto the applicator film as a type of carrier and, like labels, separated from this carrier.
  • the Applizierfolie is usually a continuous strand in the context of such an embodiment.
  • the two carrying handle film sections are supplied together with an application film, the application film remaining on the carrying handle film sections.
  • the Applizierfolie is provided in the context of such a configuration as a continuous strand, it is expedient to provide a perforation or weakening line in the form of the handle assembly so that then the individual handle assemblies can be separated with the two handle film sections and the correspondingly shaped Applizierfolie.
  • the two carrying handle film sections can also be connected by an applicator film, which has the shape of a conventional carrying handle.
  • the handling is then similar to a conventional handle assembly with a continuous handle film, but according to the invention at the gap of the handle sheet a slight buckling is possible.
  • the Applizierfolie is then so thin to choose that it does not affect the buckling and also produces no significant Aufsp Son cement.
  • the Fig. 1 shows a filled and sealed side gusseted bag, which is preferably first prepared as a prefabricated unfilled gusseted bag and then subsequently filled and sealed.
  • the gusseted bag comprises two opposite front walls 1 and two gussets 2a, 2b, which respectively connect to the front walls 1 via side edges 3 and connect the front walls 1 to each other.
  • the side folds 2a, 2b have centrally between the respective associated side edges 3 each extending in a bag longitudinal direction I crease line 4, wherein at one of the side folds 2a on a bag outside a carrying handle assembly 5 is fixed, which has a carrying handle film.

  • the Fig. 2 shows a detailed view of the handle assembly 5 at the associated gusset 2a. It can be seen that the carrying handle assembly in a transverse direction q has a width b T , which is less than 60% of the width b Sf of the side fold 2a, wherein additionally the distance a of the handle assembly 5 to the two adjacent side edges 3 each at least 15 mm is.
  • the width b Sp of the gap S is usually between 2 mm and 20 mm, preferably between 5 mm and 15 mm, for example about 10 mm.
  • Fig. 2 is also indicated by a hatching that the carrying handle assembly 5 as seen in the longitudinal direction I is attached to end portions 7 and between the end portions 7 has a handle portion 8.
  • the carrying handle assembly 5 is preferably at the end portions 7 with adhesive 9 (see Fig. 3 ) is externally mounted on the associated gusset 2a, while the handle portion 8 is exposed, so that a user can engage behind the grip portion 8 when the user's hand is inserted between the associated gusset 2a and the handle film portions 6a, 6b.
  • the two handle film sections 6a, 6b then form a uniform handle for a user, wherein the gap S is expediently dimensioned so that a user when handling the two handle film sections 6a, 6b can easily engage behind the handle portion 8, but in addition also the buckling
  • the gusset 2a can easily be done on the bending line 4, without causing the handle assembly 5 is disturbing in any way in the way.
  • the handle assembly 5 is typically placed on the bag sheet portion forming the gusset 2a before the gusset 2a is formed by either folding the bag film or by joining a plurality of pieces of the bag film to a bag body. Regardless of whether the gussets 2a, 2b fed as a separate film strips or formed from a material web, each required manufacturing process is not significantly affected by the handle assembly 5 according to the invention, because both the crease line 4 and the side edges 3 remain free. Since the handle film itself does not have to be kinked, there is also no significant spreading effect on the associated first gusset 2a.
  • the two carrying handle film sections 6a, 6b are usually arranged mirror-symmetrically to the bending line 4, wherein the gap S runs straight over its entire length and has a same width b Sp .
