Definitions

  • the invention relates to a package of two layers for flexible fabrics such as textiles, which are compressed into batches of several stacked to cause a reduction in volume, as well as packaged in this packaging packaged goods.
  • baling When compressing into multi-layered packaged goods, so-called baling, a volume reduction of the packaged goods is essentially achieved by pressing air out of the packages and the goods contained therein.
  • Packages suitable for this process are known.
  • mosquito nets are sealed in polyethylene or polypropylene bags, into which holes having a diameter of about 0.5 cm are punched.
  • the air escapes through the holes in the folded nets and between the net and the foil packaging.
  • a disadvantage of these punched holes is that through them dirt also finds its way into the interior of the packaging and to the goods packed therein. Through the punched holes, the goods come into direct contact with the environment. Especially with textiles soiling of new goods are extremely undesirable.
  • film packages may undesirably retain moisture in the package under certain circumstances.
  • mold growth was occasionally observed despite prolonged storage prior to sale or distribution despite the punched holes.
  • the WHO recommends that mosquito nets equipped with long-term insecticide be provided with a laundry indicator that can not be bleached when washed, which clearly shows the batch number or production number of the network. If such information is to be seen both externally on the packaged goods and permanently on the goods themselves, the packaging must usually also be provided with the appropriate information in addition to the goods themselves. This can be achieved, for example, by producing small quantities of packaging with the corresponding label. or the respective marking must be applied to the packaging in an additional step.
  • the object of the invention is to provide a suitable for baling packaging, which does not have the disadvantages described above. It is intended to reduce the incidence of mold on the packaged goods and provide a means of simplifying the packaging marking. In addition, they should be made of easily rotting or compostable material to make a contribution to reducing the amount of waste.
  • a package for flexible fabrics comprising a lower and an upper layer which lie on the edges of a flexible, sheet material with a bursting pressure of at least 120 kPa, wherein a) the upper and lower layers along at least B) at least a portion of the interconnected edges are connected in segments, and c) another portion of the superimposed edges as an opening for insertion of the flexible Sheet is provided.
  • the upper and the lower layer connecting and non-connecting segments are alternately arranged.
  • the unconnected segments allow the air to escape during baling, while the connected segments ensure that the upper and lower layers are not bent too far apart. Since the openings for venting are located laterally at the edges of the package and usually without the pressure of the escaping air during baling, the penetration of dirt is hindered.
  • the inside goods are not like in packaging with punched holes in direct contact with the environment outside the packaging. This advantage is particularly pronounced when at least one of the two layers is folded inwards at the edge and the side of the fold oriented in the direction of the opposite layer is connected in segments to the other layer, since the fold shields the product from the environment. Surprisingly, it has been found that even conventional 50g / m 2 unbleached crepe paper, which is otherwise used to make coffee filters, has sufficient strength to be used in the packages of the present invention.
  • a porous material such as paper, woven fabrics or fleeces of natural fibers or biodegradable plastic fibers are used as the material for the two layers, which are permeable to air and thus complicate the formation of mold, are comparatively good compostable and can be produced from renewable raw materials.
  • the goods provided with a marking such as a laundry label
  • a marking such as a laundry label
  • a closure device in such a way that the label protrudes from the package and is fixed with the closure on the packaging, so that the license plate from the outside is well readable.
  • additional labeling of the packaging with a specific reference to the individual goods marking such as a batch number, etc. superfluous.
  • the packaging can be pre-produced in large quantities, and a separate step for the labeling of the packaging is not required. The occurrence of goods with mismatched packaging is reduced.
  • the packaging according to the invention comprises two layers, a lower and an upper layer, which lie on one another at the edges. Since a flexible sheet material is used, it can adapt to the contours of the goods to be packaged, especially when baling excess air from the packaged product and the packaging is pressed out. In this case, the dimensions of the packaged goods can change, and the flexible packaging material also adapts to this, so that the largest possible volume reduction during baling can be achieved. According to the invention, a flexible material with a bursting pressure of at least 120 kPa, preferably 130 kPa and particularly preferably at least 140 kPa, is used, measured in accordance with ISO2758. This survives the forces occurring during baling and the intended transport or storage and handling of the packaged goods.
  • paper, nonwoven fabric, woven fabric, knitted fabric and plastic films which have a corresponding bursting pressure are suitable for this purpose.
  • These include, for example, long-fiber paper, crepe paper, polyethylene or polypropylene nonwovens, ce- nonwoven nonwovens, cotton, jute and linen fabrics, leather and imitation leather.
  • materials are preferably used which are porous, ie permeable to air, but retain solids such as paper, in particular creping and filter paper, textile fabric and knitted fabric and nonwovens.
  • packaging made from natural raw materials such as pulp fibers, cellulose, cotton, jute and linen is particularly preferred.
  • the paper made of pulp fibers is ideal because it is biodegraded very quickly, ie rotted.
  • crepe paper with a specific weight of at least 40 g / m 2 , preferably at least 45 g / m 2 and particularly preferably of at least 50 g / m 2 is used as the material for the lower and the upper layer. It is a long-fibred and porous paper that is compressed during production and therefore has a good extensibility of about 5 to 7%.
  • the crepe paper is made of pine sulfate pulp, since pinewood can be used to produce particularly long-fiber paper. Surprisingly, it has been shown that such, so far only used for coffee filter paper has sufficient mechanical strength to withstand the baling and robust handling such as dropping from a truck unscathed.
  • the upper and lower layers of the package form a pocket into which the product to be packaged is inserted.
  • the packaging according to the invention can therefore also be referred to as a packaging bag or bag-shaped packaging.
  • the two layers according to the invention are connected to each other along at least 50%, preferably along at least 60% of their adjacent edges, based on the total length of the superimposed edges.
  • the width in which the two layers are connected to each other is the dimension of the connection perpendicular to the outer edge in the plane of the superimposed layers. It depends, inter alia, on the packaging size, packaging material and method chosen for joining the two layers and can be easily adapted by the person skilled in the art.
  • a particular feature of the invention is that the upper and the lower layer are not connected to one another in the entire area in which they are connected to each other, but in at least one section are connected to each other in segments.
  • segment Connected by segment means that in this section segments in which the two layers are connected to one another alternate with segments in which the two layers are not connected to one another. Through the openings created by the unconnected segments, the excess air can escape during the baling, while the connected segments ensure the fixation of the two layers. During baling, the two layers do not spread too far apart due to the fixation and after baling the two layers are correctly aligned due to the fixation and the wrapped goods are thus enveloped and protected by the packaging.
  • segmentally connected segments are preferably alternately connected segments with a length of 1 to 15 cm, preferably 3 to 12 cm and particularly preferably 5 to 8 cm and unconnected segments with a length of 1 to 15 cm, preferably 3 to 10 cm and more preferably 5 to 6 cm arranged.
  • a segment-connecting section comprises at least 2 unconnected segments, between which a connected segment is arranged.
  • a segment-connected section preferably comprises at least 3 unconnected segments between which there are 2 connected segments, the unconnected and connected segments alternately in the order non-composite segment (nvS) -connected segment (vS) -nvS-vS-nvS are arranged.
  • segmented sections are considered to fall under connected sections.
  • at least 50% of the joined edges are connected in segments, based on the total length of the joined edges.
  • segment-wise connected sections are arranged opposite one another. This is often achieved even if the segmented sections are arranged symmetrically.
  • the upper and the lower layer of the packaging can be connected to one another according to the invention by any method known to the person skilled in the art for the respective material. These methods include, for example, folding, folding, embossing, gluing, sewing, stapling, riveting, welding and / or sealing. For example, embossing, gluing, sewing, folding and stapling are particularly suitable for paper.
  • the superimposed edges of the upper and lower layers can be directly connected to each other.
  • one of the two layers or both layers may have an inwardly folded edge and the two layers may be joined together by means of the folded edge.
  • the folded part of the edge inside, i. between the two layers, so that the side of the inwardly folded edge facing towards the other, opposite layer is connected to the other layer.
  • the folded part of the edge inside, i. between the two layers, so that the side of the inwardly folded edge facing towards the other, opposite layer is connected to the other layer.

  • the inwardly folded edge may also be on the outside such that the edge of the second layer is within the folded first edge.
  • the second layer facing inner side of the folded edge of the first layer is connected to the outside of the second layer. If both the top and bottom layers have such a convolution inwardly, and the folded portions of the edges are both in the interspace of the two plies and are joined together, this can give more leeway to the height of the package. It is particularly advantageous in a segment-wise connected section, which is located along an inwardly folded edge, that the fold formed by the inner fold shields the packaged in the area provided for the outflow of air unconnected segments of the environment and protects. According to the invention, a further portion of the superimposed edges of the upper and the lower layer is provided as an opening for insertion of the packaged goods. After the packaging material has been inserted, the section provided as the opening can be closed by the methods described above, like the remaining edges which have already been joined together.

  • Another object of the present invention is the use of the above-described packaging for packaging flexible fabrics.
  • These flexible fabrics include, in particular, textiles, which include home textiles, clothing textiles, garden textiles, outdoor textiles and the like. Textiles are usually folded for packaging in order to reach small packing dimensions. In doing so, air regularly gets between the individual layers of the folded textiles. In order not to unnecessarily fill the transport volume with air, textiles are often reduced to a smaller volume by baling presses. Since textiles are usually made of flexible materials, they survive the process of baling without damage.
  • a further subject of the present invention is the production of a package as described above comprising the steps of a) cutting the upper and lower layers and
  • Particularly preferred can be packaged with the packaging according to the invention textiles, which are equipped with long-acting insecticides.

  • the nets In order to provide effective protection over a longer period, the nets must be impregnated so that the insecticides are not lost even after a large number of washes.
  • Corresponding nets treated with specific insecticide-binder combinations are also referred to as LLINs (Long Lasting Insecticidle Network).
  • pyrethroids are used almost exclusively as insecticides since this class of insecticides not only has a high lethal effect for the insects with at the same time low toxicity for mammals, but also the insect is put out of action by a rapid paralysis before it becomes an insect Sting and thus the transmission of the disease can come (so-called knock-down effect).
  • Long-term insecticide-treated textile materials are used, for example, in the form of covers or covers, for example for duvet covers, mattresses, pillows, curtains, wall coverings, carpets, window, cabinet and door curtains, blankets, tarpaulins and tarpaulins.
  • the packaging according to the invention is particularly suitable for packaging nets equipped with long-term insecticides, in particular mosquito nets.
  • Such networks are described in WO 2005/064072 A2. These nets are mainly used in areas where there is a high risk of infection with malaria. Unfortunately, in these areas, waste management and waste recycling are poorly developed, so that the use of easily decomposable and less polluting packaging than polyethylene or polypropylene films has significant environmental benefits.
  • the long-term insecticide-treated materials have in common that they release the insecticide only in small doses. Therefore, textiles treated with long-term insecticides can be packed very well by the packagings according to the invention.
  • unconnected segments of the packaging can escape during baling the superfluous air without leading to a hazard to the environment or people.
  • a completely closed packaging is not necessary, therefore, as the packaging material preferred porous materials such as paper can be used, which complicate fertilizer mold.

Since the packaging is marked by the protruding and externally readable on the outside of the packaging fixed label or mark, an additional mark on the packaging is unnecessary and discrepancies between packaging label and content should occur much less frequently.
  • This embodiment of the invention also provides an easy way to package the long-term insecticide-labeled recommendation issued by WHO at the 12th WHOPES Working Group Meeting from 8 to 1 December 2008 in Geneva, Switzerland Comply with mosquito nets. Thereafter, such mosquito nets are to be equipped with wash-resistant, durable labels, on which at least the batch number of the production is specified.
