A packaging device with a fake-proof adhesive tape is proposed, including a body; a cover (11) integrally formed with the body (10), for sealing an open end of the body; a fake-proof adhesive tape containing a thin sheet of substrate (1), and attached to the cover for adhering the cover to the body; a first adhesive layer (6) applied over a first surface of the substrate, for attaching the fake-proof adhesive tape onto the cover; a fake-proof mark layer (2) printed on a second surface of the substrate, and being adherent with the substrate; a colored layer (3) for covering the mark layer and the second surface of the substrate; a transparent or semi-transparent viscous film (4) applied over the colored layer; and a second adhesive layer (5) formed on the viscous film, for adhering the fake-proof adhesive tape to the body. Adhesion between the coloured layer and the mark layer is larger than that between the coloured layer and viscous film, adhesion between the substrate and the mark layer is larger than that between the viscous film and coloured layer and adhesion between the coloured layer and substrate is smaller than that between the coloured layer and viscous film.
