Definitions

  • Packaging for bulk goods in particular bags of plastic film
  • the invention relates to a package for bulk materials, in particular a bag made of plastic, with a packaging wall enveloping the bulk material and at least one multi-layered wall region of at least one inner layer and at least one outer layer, wherein each layer has at least one air-permeable surface piece.
  • Known packages are bags or sacks made of a film, in particular plastic film, which are used to encase a wide variety of debris or
  • Fillings such as cement, fertilizers or the like products, which are produced for example in the building materials industry or the chemical industry serve.
  • the invention has for its object to improve a package of the aforementioned genus such that in addition to a structurally simplified design ensures optimal ventilation and at the same time the dusting of the contents is prevented.
  • the invention provides that between the inner layer and the outer layer at least one guide element for the air-permeable surface pieces passing air flow is arranged.
  • the present invention arranged guide affects the flow of escaping from the packaging interior air, so that a straight or direct air passage through the multi-layered wall portion of the Packaging wall and the associated leakage of solid particles of the introduced contents is advantageously prevented.
  • the strong change or deflection of the flow of the escaping air flow causes, due to the higher inertia of the solid particles, an almost complete separation of the solid particles from the air flow passing through the multi-layered wall region. It is possible, for example, for a plurality of guide elements, which are arranged opposite one another in the multi-layered wall region, to form overlapping regions.
  • the guide member is at least a portion of an air-impermeable intermediate layer, which is arranged such that at least the air-permeable surface portions of the inner layer and / or the outer layer are covered by the intermediate layer.
  • Interlayer which may for example be a film, also serves as a baffle or Abscheideorgan for discharged with the escaping air flow solid particles. Due to the intermediate layer projecting into the air flow and the associated deflection of the air flow, regions with increased flow or flow occur in the multi-layered wall region.
  • the guide member is preferably formed from a folded edge of a longitudinally folded, the package wall forming flat web.
  • the guide member is thus part of the packaging wall and the folding of the edge region of the flat web allows advantageously simple way to create such, between the layers of the multilayer wall region arranged guide element.
  • the preferably continuous in the packaging longitudinal direction extending guide ensures optimal coverage of possibly congruent to each other arranged air-permeable surface pieces of the inner and outer layer of the multilayer wall region.
  • the guide member is formed as a separately arranged between the inner and outer layer of the multi-layer wall portion arranged film strip.
  • Such film strips can be arranged in an advantageously simple manner both in sections and over the entire length of the double-layered wall region extending between the inner and outer layer.
  • the film strip can then be fixed over one of its longitudinal sides to at least one of the layers of the multilayer wall region.
  • predetermined partial surfaces of the guide element are connected at least in sections with at least one of the layers of the multilayer wall region.
  • the guide element can be fixed in an advantageously simple manner in the multi-layered wall region.
  • a cohesive connection can take place both between the inner layer and respectively associated sub-surfaces of the guide element and between the outer layer and respectively associated sub-surfaces of the guide element.
  • the packaging wall is a folded flat web whose mutually overlapping edge regions form a multi-layer wall region.
  • the layers of the multilayer wall region produced by means of the overlapping edge regions and the guide element arranged between the layers can be fixed to one another in a desired arrangement with the aid of an integral connection such as welding and / or gluing.
