    摘要： The invention relates in general terms to a device for production of a packaging precursor, wherein the packaging precursor consists to an extent of at least 80% by weight, based on the packaging precursor (1000), of a sheetlike composite, wherein the sheetlike composite includes: i. a composite plastic layer, ii. a composite carrier layer, iii. a first composite edge region, iv. a second composite edge region, wherein the device includes, as device constituents in a flow direction: a) a flat transport unit designed to transport the flat sheetlike composite, wherein the transport unit includes a transport surface designed to bear the composite; downstream of that b) a first heating unit designed to heat the first composite edge region, where the first heating unit includes energy release segments; downstream of that c) a contacting unit designed to bond the first composite edge region to the second composite edge region; wherein the first heating unit is designed to release energy in the flow direction. The invention further relates to a method, to a packaging precursor obtainable by the method, to a packaging precursor and to a use of the device.

    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.
