摘要： The invention relates to a container precursor comprising a wall, wherein the wall a) surrounds an interior region, and b) comprises a first wall region and a second wall region; wherein the first wall region comprises a first layer sequence comprising a first wall layer, a second wall layer and a third wall layer as overlying layers from the interior region outwards; wherein, in the first wall region, a second carrier layer is characterised by a smaller layer thickness than a first carrier layer, or a third carrier layer, or both; wherein the second wall region comprises a second layer sequence comprising first wall layer, a second wall layer and a third wall layer as overlying layers from the interior region outwards; wherein, in the second wall region, the second wall layer is connected to the third wall layer; wherein, in the second wall region, the third carrier layer is characterised by a larger layer thickness than the first carrier layer, or the third carrier layer, or both. Further, the invention relates to a process for manufacturing a container precursor, a container precursor obtainable through this process, a closed container, a process for manufacturing a closed container, a closed container obtainable through this process, a use of the aforementioned container precursor, and a further use of the aforementioned container precursor.
