Definitions
- 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 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. 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 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.
