A film composite with protection against tampering includes a base film, which is arranged as the lowermost layer in the film composite, and a cover layer, which is arranged as the uppermost layer in the film composite. The film composite further includes an intermediate film, which is arranged between the base film and the cover layer, and a laser-inscribable layer, which is arranged in the film composite between the base film and the intermediate film. Lines of weakening are provided in the film composite, which run within the base film and within the intermediate film.
