Claims
- 1. Tagging material for the production of a tag for securing to an article to enable the presence of the article to be detected, and comprising tape having a first surface coated with pressure sensitive adhesive and a second surface opposite the first surface coated with a release agent, the tape including a continuous substrate of synthetic plastics material, and a continuous flat ribbon of electromagnetic sensor material capable of being detected by detection equipment, said ribbon being located on the same side of said tape as said pressure sensitive adhesive, said tape being self and traverse wound.
- 2. Tagging material as claimed in claim 1, wherein the flat ribbon comprises at least a continuous metal layer and a perforate metal film adhered to said substrate.
- 3. A tagging material as claimed in claim 1, wherein the substrate is a film of oriented synthetic plastics material having a thickness of from 30 to 60 microns and a width of from 2 to 10 mm.
- 4. A tagging material as claimed in claim 3 wherein the film is of monoaxially oriented polypropylene.
