Definitions

  • the present invention relates to a packaging system, which has a Umverpa- ccess and at least partially inside the outer packaging attached air cushion system.
  • the invention is characterized in that the outer packaging and the air cushioning system are formed from compatible thermoplastic materials.

  • Previously used reusable packaging for items are usually limited to transport packaging such as pallets, boxes, containers or the like.
  • Sales packaging that is delivered to the end user are predominantly disposable and can only be partially recycled. These simple packages consist of cardboard with cardboard inserts, foam or polystyrene inserts to protect the packaged goods.
  • the inserts are usually pack-specific shaped and have proven themselves in practice.
  • One problem, however, is the disposal of the packaging, especially in the case of large-volume goods.
  • fillers Another option for protecting the packaged goods during transport is the use of fillers, which are introduced into the packaging space together with the packaged goods.
  • Plastic fillers, packaging chips or simply paper strips can serve as fillers.
  • valveless bubble bags are also be used as fillers.
  • Air cushion upholstery films or mats are used to cover the packaged goods.
  • inflatable cushioning elements are also used, which consist of air-filled or gas-filled elastic chambers and thus protect goods that are sensitive to pressure or impact.

  • inflatable packaging are known, which are used directly as transport packaging.
  • the utility model DE-GM 91 05 966 can be cited, which describes an inflatable packaging of a double foil, which consists of corresponding chambers, which are filled via a valve with air.
  • the outer film is less elastic and serves as protection against impact while the inner film is very elastic and encloses the packaged goods.
  • the package may be vented after use, wound into a roll and reused.
  • the inflatable cushioning material can be loosely inserted into the packing space or firmly connected to the outer packaging.
  • the use of a "balloon" or “pad” can be used which after inserting the packaged goods in inflated a carton.
  • WO 1994/018091 describes a packaging device in which the foil bag is reversibly connected to the underside of the lid of the packaging box and also filled via a valve in the lid.
  • the published patent applications DE 38 13 309 and DE 38 27 858 describe such a packaging unit for automated packaging of commissioned goods, wherein after insertion and closing of the outer packaging, an inner plastic bag is inflated from the outside and then welded.

  • a box-shaped transport container which is designed with one or more variable-volume gas containers whose filling and drain valve is arranged for the respective gas container in the container wall.

  • a packaging system which is stackable is proposed in the published patent application DE 10 2013 020 198 AI.
  • a transport container made of polypropylene with internal inflatable air cushioning is used.
  • a disadvantage of existing packaging systems is that they are due to different plastic materials used or insufficient resistance not or only poorly recyclable material and therefore need to be energetically utilized or deposited in the worst case.
  • a disadvantage of the technical solutions for a packaging system according to the prior art is further that the outer packaging body often has insufficient mechanical properties, if at the same time a stackability in combination with the flexible packaging of the packaging is required to minimize storage capacity and to ensure a low return effort.
  • the object of the present invention is therefore to specify a packaging system which in particular has a high recyclability, so that the individual constituents of the packaging system are uniformly recycled and, where appropriate, can be processed into a new packaging system.

  • the recyclability of the packaging system through material recycling is of particular importance. Mixtures of different polymers are generally incompatible with each other, ie the resulting properties such as the mechanical properties of these mixtures are insufficient, so that a high quality reuse is not possible.
  • the recyclability of the present systems is achieved by using compatible or compatible polymers and preferably identical polymer classes for both requirements for the respectively different requirements of the outer packaging and the air cushion system.
