| abstract |
The invention relates in general terms to a device for the production of a container precursor, wherein the container precursor consists to some extent of at least 80% by weight, based on the container precursor (1000), of a sheet-like composite material, wherein the sheet-like composite material includes: i. a plastic layer of composite material, ii. a carrier layer of composite material, iii. a first composite edge region, iv. a second edge region of composite material, wherein the device includes, as constituents of the device in a flow direction: a) a flat transport unit designed to transport the composite material in the form of a flat sheet, wherein the transport unit includes a transport surface designed to support the composite material; downstream of that b) a first heating unit designed to heat the first composite edge region, wherein the first heating unit includes energy release segments; downstream therefrom c) a contacting unit designed to bond the first composite material edge region to the second composite material 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 package precursor obtainable by the method, to a package precursor and to a use of the device. |
