  • Glass bottles have due to their substantially cylindrical shape the disadvantage that a very dense and space-saving storage is hardly possible. Glass bottles are limited to this form by their manufacturing process. Although other forms are available from glass, but these require some extra effort in the production and often lead to otherwise disadvantageous, for example, less stable, glass bottles. Due to their fragility, glass bottles generally have a considerable disadvantage, which also entails a risk of injury. As a result, glass bottles are banned at many major public events. In addition, glass bottles have a considerable weight, which leads to increased energy consumption during transport. It is also used for production Of glass, even if the glass used for this purpose comes from recycling, a fairly high energy consumption necessary. In addition, aggravating an increased transport costs. Glass bottles are usually prefabricated in a glassworks and must then be transported using significant transport volumes to the beverage bottling operation.
  • non-dimensionally stable containers bypass containers which are made of foldable composites, so-called laminates.
  • laminates usually contain, in addition to a multiplicity of polymer layers, a cardboard layer which gives them dimensional stability.
  • these laminates usually have a barrier layer, which increases the tightness. This layer is often made of aluminum.
  • the containers are typically made by folding the laminate and sealing certain laminate areas. Due to this type of production, the variety of shapes of these containers is limited. Thus, the laminates can not fold arbitrarily without loss of their tightness.
