6. :

A disposable inner bag liner according to claim 1, wherein the first alignment means defines a protrusion comprising the first alignment surface.

7. :

A disposable inner bag liner according to claim 1, wherein the first alignment means defines a recess and/or hole adapted to by engaged by the second alignment means.

8. :

A disposable inner bag liner according to claim 1, wherein the second alignment means defines a recess and/or hole adapted to be engaged by the first alignment means.

9. :

A disposable inner bag liner according to claim 1, wherein the first alignment means defines an alignment leg protrudes from at least a part of an outer rim of the first flange and/or the release liner.

10. :

A disposable inner bag liner according to claim 9, wherein the alignment leg protrudes along the entire outer rim of the first flange.

11. :

A disposable inner bag liner according to claim 1, wherein the alignment means comprises a geometrical shape indicating a corresponding shape of the second flange.

12. :

A disposable inner bag liner according to claim 11, wherein the geometrical shape protrudes from the first flange.

13. :

A disposable inner bag liner according to claim 11, wherein the geometrical shape defines a line on the surface of the first flange.

23. :

A disposable inner bag liner according to claim 1, wherein the closed end of inner bag liner in a compacted state is provided with a cover.

24. :
