1. A cartridge comprising: at least one reception chamber extending in a longitudinal direction for a medium to be dispensed, the at least one reception chamber havingan end face and a cartridge wall bounding the reception chamber, the end face and the cartridge wall being injection molded in one piece,the end face having an outlet for the medium,the cartridge wall having a first film, the first film forming an inner cartridge wall and being an innermost cartridge surface extending over a total length of the cartridge wall up to the end face, and the inner cartridge wall having an internal diameter that is constant over a total length of the cartridge wall up to the end face when the first film is disposed inside the reception chamber, and being nonreleasably connected to the cartridge wall,the end face further having a second film at a surface facing the reception chamber, the second film extending over the entirety of the end face and being a separate element from the first film and non-releasably connected to the end face, to the first film, and to the cartridge wall between the cartridge wall and the first film. 2. The cartridge in accordance with claim 1, further comprising a piston configured to be introduced into the reception chamber at an end of the cartridge that is remote from the end face, the piston being sealingly displaceable along the cartridge wall in the longitudinal direction. 3. The cartridge in accordance with claim 2, wherein the piston has a third film on a surface facing the reception chamber. 4. The cartridge in accordance with claim 1, wherein the cartridge wall has a wall thickness of at most 2 mm. 5. The cartridge in accordance with claim 3, wherein one of the first film, the second film, and the third film has a thickness of at most 0.2 mm. 6. The cartridge in accordance with claim 1, further comprising a connection device configured to connect the cartridge to a second cartridge. 7. The cartridge in accordance with claim 5, wherein one of the first film, the second film, and the third film is a multilayer system. 8. A multicomponent cartridge having at least two cartridges, each cartridge being designed in accordance with claim 1, wherein the two cartridges are capable of having one of a first arrangement and a second arrangement, the two cartridges being arranged next to one another with respect to the longitudinal direction in the first arrangement, the two cartridges being arranged in one another so that one cartridge surrounds the other cartridge in the second arrangement. 9. The multicomponent cartridge in accordance with claim 8, wherein the two cartridges are fixedly coupled to one another via a connection device. 10. The multicomponent cartridge in accordance with claim 8, wherein the two cartridges each include an outlet that forms a common connection piece configured to cooperate with an accessory part. 11. The multicomponent cartridge in accordance with claim 10, further comprising a closure part configured to cooperate with the connection piece and having two plugs, each of the plugs being configured to engage into a respective outlet of the outlets of the two cartridges to close the respective outlet. 12. The multicomponent cartridge in accordance with claim 8, wherein the reception chambers of the two cartridges have different volumes. 13. The multicomponent cartridge in accordance with claim 10, wherein the accessory part is one of a closure part and a mixer. 14. The cartridge in accordance with claim 2, wherein the innermost cartridge surface of the first film has a reduced friction in comparison to a surface of the cartridge wall. 15. The cartridge in accordance with claim 1, wherein the cartridge is made from biopolymers. 16. The cartridge in accordance with claim 4, wherein the cartridge wall has a wall thickness of at most 1.5 mm. 17. The cartridge in accordance with claim 4, wherein the cartridge wall has a wall thickness of at most 0.8 mm. 18.
