Definitions

  • Container to hold flexible contents and film packaging
  • the invention relates to a container for receiving a flexible content and to a film packaging having the container.
  • Containers and film packaging made from thin, flexible films are known from the prior art.
  • filled spaces are usually provided in or on the wall of the container. Because of the symmetrical arrangement and shape of these filled spaces, they can easily burst if only one of the spaces is damaged. As a result, the container quickly loses its structural integrity.
  • DE 20 2005 016 704 U1 describes, for example, a closed bag for holding liquids, bulk goods or objects, with a bag wall made of plastic and / or a metal foil, with bulging cushions being arranged in or on the bag wall, which stiffen the bag wall .
  • EP 2 879 972 B1 and EP 3 178 753 B1 relate to a method for forming a flexible container, with at least a section of the flexible materials being connected to one another so that at least one support structure element is formed.
