  • the bag material used cannot be separated and connected by means of cut-off welding, it is particularly advantageous to connect the side edges of the bag to one another over a width of several millimeters by heat sealing. Due to the surfaces of the coating facing the interior and the welding of these opposite sealing coatings, it is sufficient to apply the sealing coating to the paper in a thickness which corresponds to half the sealing material thickness necessary for joining the side edges.
  • the bottom area is provided for removing the hygiene articles.
  • the bottom area can have a perforation. The perforation can in particular be made in the vicinity of the side edges parallel to the longitudinal dimension of the bag. Provision can also be made for the bags to be provided as wicket bags or pen-stack bags for filling with hygiene articles.
  • the bottom area can have an opening facing the interior of the bag.
  • the bottom area can have a protruding material section on the front or the rear wall of the bag. This can be used to close the bag.
  • the protruding material section can also have two wicket pin holes. In order to prevent the material from tearing off when it is pulled from the wicket pin, it can be provided that the protruding material section is folded back on itself and the wicket pin holes are arranged in this double-layered section.
  • the side edges sealed to one another are designed as flat seams.
  • flat seams are particularly useful for connecting the two layers of material.
  • the layers can be connected to one another particularly easily when the flat material web runs through a welding station, for example by vertically lowering welding bars.
  • the seam width can be selected so that two flat seams of adjacent bags are produced at the same time and can be separated in a subsequent step.
  • the predetermined width of the side edges is between 5 to 15 mm, preferably 8 to 12 mm, particularly preferably 10 mm.
  • the seam width can be selected depending on the bag size or the article to be packaged, for example, in order to be able to provide the necessary stability individually.
  • the bag in the filled state, can have a body formed by the front and rear bag walls, which body has a front surface, a rear surface, two side surfaces connecting the front surface and the rear surface, and two top and bottom surfaces connecting the front surface and the rear surface and adjoining the side surfaces having.
  • the flat seams run in the area of the side surfaces.
  • the front and the rear bag wall can arch around the packaged articles, so that the flat seams run in the area of the side surfaces produced by the article shape.
  • the flat seams can protrude perpendicular to the side surfaces.
  • the flat seams can be heat-sealed to the side surfaces by means of a sealing lacquer applied to them or to corresponding sections of the side surfaces.
  • At least one corner protruding from the body is formed at the transitions between the top surface and the adjoining side surfaces.
  • the folding arrangement provided in the head area can have an inserted head fold, so that at least two opposite corners protruding from the body are formed at the transitions between the head surface and the adjoining side surfaces.
  • the head fold can in particular be designed such that the fold arrangement has three folds in the head area, so that a fold is inserted between the front and rear wall of the bag.
  • the head fold can be used, for example, to create a stand with which the filled bag can be placed upright without falling over.
  • the head fold can have the effect that the bag has an attractive appearance or that more articles can be accommodated in the bag. If a head fold is provided, the bag has four instead of two corners in the head area, which are created due to the two outer folds of the corresponding fold arrangement.
  • the head area can in particular have two corners.
  • the head area can in particular have four corners. For optical and spatial reasons, it can be useful to fold the protruding corners back onto the bag body.
  • the corners folded back onto the top surface can be heat-sealed to the top surface by means of a sealing lacquer applied at least locally to the paper layer.
  • the sealing wax can be applied point-wise or flat on the inside of the corners and / or on the corresponding points of the top surface. Since the paper cannot be welded "outside-to-outside", applying the sealing lacquer to these areas means that the material can also be connected in these areas.
  • the front and the rear bag wall can be heat-sealed to one another via a flat seam arranged in the bottom area, extending in the transverse dimension and having the sealable coating in a predetermined width.
  • the flat seam protruding from the bag can be attached to the bag body, for example, by applying a sealing wax at least in sections and heating it.
  • the width of the flat seam can be dimensioned such that a flat grip strip is formed in the bottom area.
  • the grip area can in particular be formed after the bag has been filled.
  • a sealing weld can be carried out below the handle to close off the interior of the bag. Above the handle, a weld comprising a separation process to form the wicket area can also take place.
  • the bag can have a grip strip arranged in the head area, which is formed by at least partially heat-sealing the front and rear bag walls, the grip strip extending over the transverse dimension and starting from the folding arrangement in the longitudinal direction in a predetermined grip width.
  • a grip strip can be provided in the head area instead of the inserted head fold or instead of the bag being designed as a flat bag.

  • the predetermined grip width can be 4-8 cm, preferably 5-7 cm, particularly preferably 8 cm.
  • the handle strip can have a punched-out handle.
  • sealing seams with a width which corresponds to twice the predetermined width, it is possible for two side seams of adjacent bags to be produced at the same time per sealing process. In particular, it can be provided that the seams produced are severed in the middle.
  • the heating of the material web can include preheating of the sealing seams to be applied.
  • the heating can already include the heat sealing of the sealing seams.
  • the process step of separating the sealing seams can include fixing the material web.
  • the fixing preferably takes place before the sealing seams are separated.
  • the severing of the sealing seams can comprise a renewed heating of the sealing seams in order to heat-seal the material web layers which have been folded onto one another.
  • the possibly first heating of the material web and the severing of the sealing seams take place at separate stations.
  • the in Figure 1 The bag 1 shown in the unfilled state is formed from a continuous material web 24.
  • the material has a paper layer 2 and a sealable coating 3 arranged over the entire surface.
  • the paper layer 2 on the outside of the bag and the sealable coating 3 face an interior 4 of the bag.
  • the bag has a rectangular shape with a Longitudinal dimension 7 and a transverse dimension 8, the longitudinal dimension 7 being greater than the transverse dimension 8.
  • the material web 24 is folded back onto itself in the area of a folding arrangement 11 in the illustrated embodiment with an inserted head fold 22, that is, by means of three folds, so that a front bag wall 5 and a rear bag wall 6 are formed.
  • the head fold is inserted between the front and rear bag walls 5, 6 by about 6 to 7 centimeters.
  • the material web sections placed on top of one another have aligned side edges 13 which extend in the longitudinal dimension of the bag.
  • the front and rear bag walls 5, 6 are heat-sealed to one another over a predetermined width b, so that sealing seams 25, each 1 cm wide, formed as flat seams, connect the bag walls 5, 6 to one another.
  • the front and rear bag walls are not directly welded to one another, but the front bag wall 5 is welded to the head fold portion facing it and the rear bag wall 6 is welded to the head fold portion facing it.

  • a protruding material section 26 projecting beyond the bag opening 30 is provided on the rear wall of the bag 6.
  • a short material web section is also folded back on this, which is fastened at the side edges 13 also by corresponding sealing seams 25 on the rear bag wall 6.
  • two holes 27 are provided which are used to attach the bag to wicket pins. The purpose of the folding back is to prevent the holes 27 from being torn out when the bag 1 is pulled off the wicket pins.
  • Figure 2 shows in particular the folding arrangement 11, the head fold 22 on the basis of two bags 1 lying next to one another the third fold is arranged therebetween and connects the folded-back portions to one another, so that the head region 10 has the shape of a "Y" from a side perspective.
  • the sealing seam 25 follows the course of the head fold 22 and is formed on the one hand between the front bag wall 5 and the head fold portion folded back onto it and on the other hand between the rear bag wall 6 and the head fold portion folded back onto it.
  • the illustrated bags 1 also each have sealing seams 25 with a predetermined width b of 1 cm.
  • a filled bag 1 can be seen, which is an embodiment as a bag 1 with inlaid head fold 22.
  • the bag has essentially six Outer surfaces, namely a top surface 19, a front surface 15, a rear surface 16, two opposite side surfaces 17 and 18 and possibly a bottom surface 20.
  • a sealing seam 25 runs centrally on the side surface 17 and opposite the other sealing seam 25 on the side surface 18, not shown, this protrudes perpendicular to the side surface 17 or 18 from the bag 1.
  • corners 21 are formed in the edge areas of the head fold which, due to their shape and position, cannot be filled with hygiene articles and which also protrude from the bag.
  • the essentially triangular shaped corners have the paper layer 2 on their outer surfaces, as do the remaining outer surfaces of the bag 1, in particular the side surfaces 17, 18 adjoining the corners and the top surface 19 Areas not easily possible.
