Beschreibung
Zusammenfassung:	A tubular liner for sewer rehabilitation an inner tubular film; a resin-carrier layer surrounding the inner tubular film; and a mechanically protective outer film system surrounding the resin-carrier layer. The outer film system has an outer film extending in the longitudinal direction of the tubular liner. Longitudinal edges of the outer film are connected to each other in an overlapping manner in the circumferential direction of the tubular liner with connecting points. Upon the elongation in the radial direction during the insertion of the tubular liner, the connection points are elongated and may break in a sewer to be rehabilitated. The outer film features at least one layer made of a material that is mechanically very stable and is essentially not able to elongate, and at least one layer that is essentially impermeable for UV radiation and visible light.
