Definitions
- the invention relates to a bag, in particular for packaging moisture-sensitive substances, with a front wall, a rear wall and with side walls which form longitudinal outer edges with the front wall and the rear wall.
- Such bags which are used, for example, for the packaging of building materials or washing powder, generally consist of thick paper or cardboard in order to ensure their shape stability and their stackability.
- the bags are provided with a water- or vapor-tight layer, which can consist of a plastic coating or a lacquer layer and which is connected in a suitable manner to the paper bag.
- Packagings made of such composite materials are not only expensive to produce, they are also difficult to dispose of in an environmentally friendly manner, since the various materials of the bag have to be separated from one another before suitable recycling.
- the object of the invention is to so form a form-stable and moisture- ⁇ keitsab floden bag that it can be produced easily and inexpensively and can be easily disposed of and recycled linen ⁇ .
- the bag consists entirely of a liquid and vapor-tight plastic film or of a plastic composite film which has a thickness of at least 50 ⁇ m and at most 300 ⁇ m and that the longitudinal seam of the bag is not welded, but is glued.
- This configuration has the advantage that the bag can be sent directly to plastic recycling after use.
- the use of a plastic film of more than 50 ⁇ m makes it possible to manufacture and fold the bag by machine. By gluing the longitudinal seam, shrinkage that occurs during the usual welding process is avoided, so that the bag has a high degree of dimensional accuracy and stability.
- the bag is expediently a block bottom bag with at least four transverse outer edges on one end face, along which parts of the front wall, rear wall and side walls are folded over to form a block bottom.
- Block-bottom bags of this type can be stacked particularly easily and safely.
- the bag can also be a gusseted bag that is particularly simple and inexpensive to manufacture.
- the plastic film is preferably a high-density polyethylene film (HDPE), which has a thickness of approximately 100 ⁇ m. Such a thick HDPE film is particularly tear-resistant and enables the edges of the bag to be folded slightly. It is also possible to use a plastic composite film made of a polyethylene film high density (HDPE) and a low density polyethylene film (LDPE), both of which are polyolefins and are so similar in their chemical composition that joint recycling is possible without any problems.
- HDPE high-density polyethylene film
- LDPE low density polyethylene film
- the bag is also glued to overlaps of the film in the bottom area. As a result, shrinkage due to welding is reliably avoided at the bottom of the block-bottom bag or at the closed end of the gusseted bag.
- the block bottom of the block bottom bag is advantageously provided with a cover made of plastic film which corresponds approximately to the dimensions of the block bottom and which is glued onto the bottom from the outside. This gives the block-bottom bag an additional rigidity and has a homogeneous surface on its bottom side which can be easily printed.
- the bottom of the block bottom bag is glued with two mutually parallel adhesive beads that have at least a length that corresponds to the width of a long side and if the cover made of plastic film is glued to the bottom of the entire surface.
- the flaps of the block bottom can be glued to one another with little adhesive.
- the full-surface gluing of the cover to the floor ensures a particularly good seal.
- the adhesive is preferably a hot-melt adhesive, which is particularly easy to process, ensures high stability of the adhesive seams and, due to its large volume, seals the seams particularly well, particularly in the bottom area.
- Fig. 1 shows a block bottom bag open according to the invention in a perspective view
- Fig. 2 shows the block bottom bag of FIG. 1 in a plan view
- Fig. 3 shows the bottom of the block bottom bag in the unfolded state in a plan view.
- 10 denotes a block-bottom bag which is used for packaging moisture-sensitive bulk goods, such as plaster, washing powder or the like. serves and consists entirely of a liquid and vapor-tight plastic film 11.
- This plastic film 11 is a high-density polyethylene film (HDPE film), the thickness d of which is at least 50 ⁇ m. In the exemplary embodiment shown, the plastic film 11 even has a thickness of 100 ⁇ m.
- the block bottom bag 10 shown is manufactured like a paper bag on a block bottom bag machine. It has four parallel longitudinal outer edges 12, 13, 14, 15, on which the longitudinal sides 16, 17, 18 and 19 meet.
- the narrow long side 19 On the longitudinal outer edge 15, the narrow long side 19 has a protruding strip 20 which is glued to the free outer edge of the front long side 16, so that an approximately rectangular tube results, as is known per se in block-bottom bags.
- each of the narrow longitudinal sides 17 and 19 has an inner fold 21 or 22 which runs parallel to the longitudinal outer edges 12 and 13 or 14 and 15 and divides the narrow longitudinal sides into two halves which lie one on top of the other when the bag is packed with its front and rear long sides 16 and 18 is placed flat on top of each other.
- the narrow long sides 17 and 19 and the wide, front and rear long sides 16 and 18 at the lower end 23 of the bag are folded inwards in pairs and bent inwards at right angles, so that the lines shown in FIG Folding shown in lines arises as is usual with block-bottom bags.
- the overlapping parts 24, 25, 26 and 27, which form the bottom 28 of the bag 10 are preferably glued to two parallel adhesive beads 30, 31, which are close to the lower edges 32, 33 of the narrow longitudinal sides 17, 19 run parallel to these and extend to the pointed bottom plates 34, 35 formed by the wide long sides 16, 18 (FIG. 3).
- the overlapping parts of the base can also be glued to one another over the entire surface.
- the cover creates a smooth surface that is fully printed and also with a handle or the like. can be provided.
- the filled bag can be glued at the upper edge, but also welded or sewn. As a result, it can be used universally and can be used on all customary filling systems for pourable or pourable packaging goods.
- the invention is not limited to the embodiment described, but can also be used with side-gusset bags, the front and rear walls of which are closed together, including the folded-in side walls.
