Abstract: In accordance with the invention, an improved packaging system for protection against the theft of goods by overlabeling comprises a layer of packaging material surrounding the goods, a label adhered to the packaging material, and a transparent film covering the label. In contrast with conventional packaging, the outer surface of the transparent film is provided with an antiadhesive coating to inhibit overlabeling. The transparent film can be smooth or textured. The advantage of texturing, as by embossing, is to reduce the surface area to which an overlabel can adhere. The antiadhesive coating is preferably a composite layer comprising a non-adhesive base coating of silicone and a layer of "tack kill" material such as an acrylic plasticizer for neutralizing a subsequently applied adhesive. The result is that a spurious label applied on the film over the original label readily disengages in the course of ordinary package handling.
