Abstract
A sheath for wrapping objects has a sheath body which extends over a circumferential surface (4) of an object (1) and comprises at least portions of a shrink foil pre-stretched in a circumferential direction. The sheath has a significant cohesion of the sheath body, is easy to tear off, and is characterized by low production costs. At least one foil edge (5a) is provided with a pair of preformed predetermined tear zones (7) which extend in the rim portion (6a) of the foil edge with a limited depth and are mutually spaced circumferentially. The tear zones have a reduced tear and/or separation resistance as compared with adjacent foil portions.
