• the adhesive force of the adhesive layer 10a is substantially greater than the adhesive force of the adhesive layer 9. For this reason, the sealing or sealing label as a whole adheres to the object 3 with a stronger adhesive force, while the internal cohesion between the cover film 1 and the lower film section 6a is less.
• the seal or seal label according to FIG. 10 is used as follows:
• the seal or seal label is, as usual, available for use on an adhesive-repellent carrier tape (not shown). It is detached from it and then pressed onto two objects 2, 3 in such a way that the first region 4 of the seal or closure label adheres to the first object 2 and the second region 5 of the seal or closure label adheres to the second object 3.
• the sector 16 between the two areas 4, 5 lies in the area of the boundary line of the two objects 2 and 3 and is made non-adhesive by the lacquer layer 11, so that there is no undesired adhesive connection in this sector 16.
• the cover film 1 is gripped on the non-adhesive edge 11 a and at least pulled off to the extent that it is removed from the Lower film section 6a is separated. Because the adhesive force of the adhesive layer 10a is substantially greater than the adhesive force of the adhesive layer 9, the separation takes place in such a way that the cover film 1 is lifted off and the lower film section 6a remains on the object 3.
• the force to be applied in this case is independent of the surface condition of the object 3 and can be set exactly by choosing the materials used. Since the lower film section 6a is arranged exclusively in the area 5, the described partial lifting off of the cover film 1 already achieves unsealing of the two objects, i.e. the two objects are freely movable relative to each other.
• the color layer 7 on the underside of the cover film 1 adheres firmly to the underside of the cover film 1, with the exception of those areas which have been prepared with anti-adhesive varnish 8.

• the second transparent film 26 has on its underside a layer of pressure-sensitive adhesive 10 a with which it adheres to an object 3.
• the adhesives of layers 9, 25 and 10a are chosen so that the adhesive force of layer 9 is the lowest, the adhesive force of layer 10a is greatest and the adhesive force of layer 25 is between the two adhesive forces of layers 9 and 10a.
