Beschreibung
Zusammenfassung:	A self-adhesive tape comprises a polyolefin-based film formed from a sheet comprising at least one polyolefin substrate layer (4) and at least one cellular polyolefin coating layer (5) co-extruded with the substrate layer; the sheet is stretched in two directions and has cell walls which have collapsed as a result of the biaxial stretching at least on the surface (7) of the coating layer (5) which faces away from the substrate layer (4), the collapsed cells forming a plurality of projections and/or depressions which reduce the force required and/or the noise produced during unrolling of the sticky tape.
