<p>A manipulation-proof film (1) comprises a carrier layer (10), to which a hologram structure (20) has been applied. The hologram structure (20) is arranged at least partially uncoated on the carrier layer (10). If a cut (S) is made in the carrier layer (10) and the two severed halves of the carrier layer (10) are subsequently joined together again by a transparent film being stuck over them, a hologram effect disappears. This allows manipulation of the film to be established in a reliable way.</p>
