Definitions

  • the invention relates to a method for the production of film bags, which have two front sides of a multilayer composite film, V-shaped inserted side folds and a head-side bag opening, wherein the side folds terminate below the bag opening and wherein the upper end of the side folds is closed by a sealed cover film, which defines the respective gusset end on one of the two front sides.
  • the composite film On the inside of the bag, the composite film has a sealing layer of a weldable thermoplastic material and a printed, non-sealable outer layer. In the bag opening a reclosure may be arranged.
  • the flat film pouches produced in the process are loaded with filling material in bag filling devices.
  • the filling takes place at the head of the bag. After filling, the bag opening is closed.
  • a method for producing the described foil pouch is made US Pat. No. 6,068,585 known.
  • film sections which are prefolded onto a flat film web and which form the later gussets of the film bags are laid transversely to the web direction and are welded to the flat film web.
  • a film strip on which locking elements of a reclosure are formed, is placed over the end of the gussets and connected to the gussets and the film web through sealed seams.
  • a second film web is supplied, which is already provided with a counterpart for reclosing, and by longitudinal and transverse sealing seams with the lower film web to a bag-shaped sections consisting of bag-shaped sections connected, are separable from the individual bags.
  • the invention has for its object to provide a method for producing the film bag described above, in which the front sides and side folds of the film bag are formed by folding a flat material web.
  • the object is to integrate the closing of the gussets in the process flow so that the placement and fastening of the cover sheets for closing the gussets does not adversely affect the production speed.
  • the film layers lying on top of one another of the film tube formed in process step e) can be connected to form a bag string consisting of bag-shaped sections, from which individual bags can be separated. If the foil pouches to be produced are to be equipped with a reclosure, reclosures are applied transversely to the web direction onto the sealing layer of the flat film web and connected to the film web following process step b).
  • film labels are used from a cover film and sealed onto the flat film web. Thereafter, the film web passes through with sealed film sheets other workstations in which optionally reseals sealed and gussets are formed before the film sheets are circumferentially sealed onto the film web that the upper ends of the gussets between the film web and the sealed film sheets are included.
  • the laying on and fastening of the foil strip on the one hand and the further sealing process on the other hand are assigned to different workstations in the context of the method according to the invention. By this division, the measures for sealing the gussets are integrated into the process flow so that the production speed is not impaired.
  • a multilayer composite film is preferably used, which has on its one side a sealing layer of a weldable thermoplastic material and on its other side a non-sealable layer.
  • a sealing layer of a weldable thermoplastic material on its other side a non-sealable layer.
  • composite films comprising a polyolefinic sealant layer and a non-sealable polyester layer may be used.
  • a further advantageous embodiment of the method according to the invention provides that the outer edges of the flattened film tube are reinforced by longitudinal sealing seams which connect the front surfaces of the film tube with the adjacent film layer of the V-shaped side folds.
  • the foil sheets extend into the region of these longitudinal sealing seams.
  • the sealed cover sheets close the gussets at their upper end usually sufficient.
  • the process sees as another Design before that the upper edges of the V-shaped inserted side gussets are connected to each other and only then are welded to the side gussets protruding film sections of the sheet of foil with the film web.
  • the following method is preferably used.
  • the outer layers of the composite films are at least partially removed by laser ablation in strip-shaped sections which extend along the edge of the window-shaped cut-outs delimiting the upper end of the lateral folds.
  • the sealing layer of the composite film is exposed locally, so that subsequently the sealing layers can be thermally connected by a sealed seam.
  • the material of the outer layer is removed by laser irradiation.
  • the laser beams penetrate during laser ablation in the material to be processed. The depth of impact remains low during a pulse, but the energy input into this layer is so high that molecular compounds are broken up and matter is ejected at sufficient energy per surface. This happens so fast that no heat can penetrate the remaining solid material.
  • the ablation thus takes place without a significant thermal load on the environment of the direct radiation exposure.
  • Each pulse of the laser breaks up a thin layer of the substrate. As the laser operates at several hundred pulses per second, a faster machining process is guaranteed.
  • the laser ablation of the non-sealable outer layer of the composite film can take place in the strip-shaped sections over the entire surface.
  • the outer layer is in the region of the window-shaped Cutouts adjacent strip-shaped section therefore removed in the form of a grid by laser ablation. It is also advantageous if a composite film is used whose outer layer is unprinted at the points which are removed by laser ablation or whose outer layer is not glued to the sealing layer in areas which are removed by laser ablation.
  • the composite foil is perforated in the surface sections in which the outer layer is removed by laser ablation.
  • the molten material of the sealing layer enters the perforation area and fills it. The molten material has no contamination and forms an effective contact surface for the sealing compound.
  • the additional measures described can be advantageously integrated into the process sequence in the following manner.
  • the material web is fed to the top, non-sealable outer layer of the first workstations in which the window-shaped punched holes are punched and removed by laser ablation strip-shaped sections in the outer layer. Thereafter, the film web is turned, the foil tape welded and carried out the further process steps.
  • the film bag shown in FIGS. 1 to 3 consists of a multilayer composite film 1, the bag inside a sealing layer 2 made of a weldable thermoplastic material, eg. As polyethylene, and bag outside a printed, non-sealable outer layer 3, z. B. made of polyester.
  • the film bag has two front sides 4, 4 ', V-shaped inserted side folds 5 and a reclosure 6 in a head-side opening of the bag.
  • the front sides 4, 4 ' are connected by an additional sealing seam 7, which forms a tamper-evident closure and is separated during the first use of the film bag.
  • the gussets 5 terminate below the reclosure 6 and are closed at their upper, in the interior of the bag projecting end 8 of a cover, which defines the respective side fold end on one of the two front sides 4 '.
  • the figures are taken from that the cover film is made up as a foil tape 9, which are wider than the gussets 5 and extend into the region of a longitudinal sealing seam 10 of the film bag.
  • the film tabs 9 are sealed onto the gussets 5 and welded to a protruding portion with the lying behind the gussets 5 front side 4 'of the film bag.
  • FIG. 4 On the basis of a very simplified representation, the method for producing the film bag is shown in FIG. 4.
  • a sealing layer of a weldable thermoplastic material and a printed, non-sealable outer layer has window-shaped cutouts 12 are introduced, which limit the upper end 8 of the gussets formed later.
  • foil tape 9 are placed from a cover and with sections a of the film web adjacent to the window-shaped punched 12 directly or with a small distance and at the laterally formed side folds 5 respectively form the upper film layer of the gussets, welded.
  • the film tabs 9 are wider than the side folds 5 formed later and are in the window-shaped punched 12 in front.
  • reclosures 6 are placed transversely to the web direction on the sealing layer of the flat film web 11 and connected to the film web 11.
  • the reclosures 6 consist of detachably connected profile strips.
  • the film web 11 passes through a folding station 13, in which gussets 5 are formed by folding the film web.
  • the previously already attached film tabs 9 project beyond the edge of the gussets and are welded to the protruding edge portions 14 with the underlying sealing layer of the film web.
  • the film web is folded into a flattened film tube 15. With longitudinal and transverse sealing seams, the superimposed film layers are joined to form a bag string consisting of bag-shaped sections 16. Furthermore, a still protruding narrow waste strip 17 is separated. From the bag string eventually individual bags are separable.
  • the foil tape 9 as well as the flat film web 11 consist of a multilayer composite film, on its one side a sealing layer of a weldable thermoplastic material, for. As a polyolefin, and on the other side a non-sealable layer, for. B. made of polyester.
  • the outer edges of the flattened film tube 15 are reinforced by longitudinal sealing seams 10 which connect the front sides 4, 4 'of the film tube with the adjacent film layer of the V-shaped side folds 5.
  • the film tabs 9 extend into the region of the longitudinal sealing seams 10 and are incorporated into these.
  • FIG. 5 which depicts the joining region at the upper end of the gussets, shows that the outer layer 3 of the composite film 1 has been completely or at least partially removed in a strip-shaped section along the upper edge 17 of the gussets by a surface treatment, preferably by laser ablation is. As a result, the sealing layer 2 of the composite film 1 was exposed at the contact surface.
  • the film layers of the side pleats 5 have been thermally bonded in the strip-shaped section by a sealed seam 18.
