Definitions
- the invention relates to a paper bag with film overlap for fine-grained bulk material such as cement, gypsum, granules, animal feed or the like, with a bottom, for example a cross bottom, and with a top opposite the bottom, in which a valve tube for filling the paper bag is arranged, wherein the paper bag is formed of an inner layer of paper and an outer layer of paper, between which at least one plastic film lies ( US Pat. No. 5,493,844 ).
- Such paper bags are well known and are widely used in commerce.
- the usual sizes are 5 kg, 10 kg or 25 kg.
- valve tube For filling a valve tube is provided, which is incorporated in the upper part and is plugged for filling on a filler neck.
- the known valve bags consist of an inner and an outer layer of paper, between which a plastic film is inserted as a water vapor barrier layer.
- the plastic film is not connected at the edges, but only loosely overlapped inserted to allow air to escape during filling of the hose.
- the overlapping edges of the middle plastic layer thus run parallel to the side edges of the paper bag and thus extend from the bottom to the top.
- the object of the invention is therefore to provide a paper bag with improved water vapor density without worsening the venting of the bags.
- the core of the invention is thus to glue an edge of the barrier layer with the inner layer or the outer layer of the paper bag in the known simple overlap. This has surprisingly meant that the venting of the bags has improved by 100% compared to the simple film overlap.
- two or more barrier layers of sheet-like material are provided which each bonded in the region of an edge with the inner layer or the outer layer, while each free other edge overlaps an underlying barrier layer.
- plastic films can be used as barrier layers, but also any other type of film or web which is thin, planar and flexible and which gives the same result.
- This also includes metal foils, polyethylene films and paper films with and without coating, wherein the coating may be, for example, a paint, plastic or metal.
- valve bag 1 with bottom 2 and upper part 3 shown schematically in plan view, wherein the bottom 2 and the upper part 3 are folded onto the front side 4 of the valve bag 1. Not recognizable is the back, which is below the front 4 and is congruent with this.
- a paper bag is made of an inner layer of paper or paper composite with a rectangular shape and a dekkungsreteen outer layer, which is also made of paper or paper composite and is rectangular. Four short cuts are made at the bottom and top edges of the two paper layers, while the rest is folded.
- Four short cuts are made at the bottom and top edges of the two paper layers, while the rest is folded.
- the inner layer of the paper bag 1 is not usually treated as it is not visible in use and also does not need to be printed.
- the congruent outer layer may have undergone such treatment that it can be easily printed and also provides a pleasing appearance.
- one or more barrier layers are now inserted between the one-piece inner layer and the likewise one-piece outer layer, the edges 8, 10 of which overlap.
- the edges 8 and 10 of the barrier layer or the barrier layers run parallel to the side edges 5 and 6 of the paper bag 1.
- the overlap area A preferably makes 1/5 to 1/20 of the width B of the paper bag 1, preferably 1/10.
- A 0.2B to 0.05B, preferably 0.1 B, applies. It should be noted that the values given are not exact values but merely indicate the desired range.
- the right edge 10 of the barrier layer overlaps the underlying left edge 8 to the area A. Further, the left in the drawing part of the barrier layer is glued to a glue line 7 on the inner layer of the paper bag 1, the distance X to the right edge 8 and parallel to this over the height H of the paper bag 1 runs.
- each barrier or barrier film adheres along one edge through an adhesive line 7 to the inner layer or outer layer of the paper bag 1, while each other opposite edge not provided with an adhesive line Part of an adjacent barrier layer overlaps, which is also attached like the aforementioned barrier layer with a glue line to the inner layer or the outer layer of the paper bag.
- adjacent barrier layers or barrier films overlap like tiles, so that always the unpaved edge of a first barrier layer covers or overlaps the attached edge of each subsequent adjacent barrier layer.
- edge of the barrier layer is meant in each case the edge 8, 10, which runs parallel to the side edges 5 and 6 of the paper bag 1, but not the upper edge 11 or the lower edge 12 which run across the upper part 3 and the bottom 2.
- the reason for this is the production of the paper sack, which is produced in a first manufacturing stage as a paper tube and cut in a further manufacturing stage to the length H.
- the barrier layer or barrier film initially also only a longitudinal extent with the edges 8 and 10, because the transverse thereto extending upper edges 11 and lower edges 12 arise only after the cut to the lengths H.
- valve 13 is formed, which is formed by a known tubular nozzle, which can be pushed under the slip 9 and thus in the cross bottom.
- the barrier layer according to the invention is provided in one embodiment with holes or perforations, for example, by needling with a needle head according to DE 203 19 771 U1 can be made. This additionally improves the escape of air.
- barrier layer With the use of a specially applied longitudinal bonding of the barrier layer, it is possible to guide the air between the inner layer and barrier layer so that a much faster occurring air outlet behind the barrier layer can take place. This applies to both a perforated and an imperforate barrier layer. After that, the air collects in front of the outer layer, where it can be removed with known technology.
