The invention provides a film-free anti-counterfeiting sticker and a preparation method thereof, wherein the film-off anti-counterfeiting sticker comprises: a release film or a transfer film, a UV resin film, a transfer film, a reflective layer, a backing layer and a bottom paper, wherein The release film or the transfer film is disposed on the top surface of the UV resin film. The UV resin film has a thickness of about 1-10 micro (μmol, mocrons), is cured by UV light, and has a holographic image of the concave and convex surface on the bottom surface. The backing layer is applied to the bottom surface of the UV resin film, and the backing layer is applied to the bottom surface of the reflective layer, and the backing paper has a release effect and adheres to the bottom surface of the adhesive layer; and the anti-counterfeit sticker manufacturing method of the film is coated with a release film bottom surface. a UV resin film is embossed on the bottom surface of the UV resin film, and is embossed by a UV lamp, and then a reflective layer is bonded to the bottom surface of the cured UV resin film, and a backing layer is coated on the bottom surface of the reflective layer. Adhesive a base paper, and if necessary, choose whether to replace the topmost release film with a one-roll film, that is, to make a finished film of the anti-counterfeit sticker, and can be used for the tearing away.

The main purpose of this creation is that the UV resin film thickness is quite thin, only 1-10 micro (μ, mocrons), so when you want to move the film anti-counterfeit sticker, you can only tear off the transfer film, can not tear the UV resin film away Freely shifting the mark, but it can effectively prevent illegal use for other purposes, and the anti-counterfeiting effect is good.

A second object of the present invention is that the UV resin film has an extremely hard and smooth watch. Surface characteristics, and can form a high degree of protection against scratches, and good durability.
