A tagging material for the production of electronic identification tags. Shown generally at (10) is a continuous tape of thermoplastic plastics material. The tape (10) comprises a film (12) having on an upper surface a coating (14) of release agent, and on a lower surface a coating (16) of adhesive. Below the adhesive coating 16 is a further film (18) having on its upper surface an antenna (20) and, electrically connected thereto an integrated circuit (22). On a lower surface of film (18) is a coating of pressure sensitive adhesive (24). The integrated circuit (22) is completely encapsulated in a flexible protective layer (26) of non-conductive waterproof material, which is preferably UV-curable, such as polyurethane.

L'invention concerne un élément d'étiquetage destiné à la production d'étiquettes d'identification électroniques. Cet élément comprend une bande (10) continue en matière plastique thermoplastique. Cette bande (10) comprend une pellicule (12) comportant, sur une surface supérieure, un revêtement (14) à base d'un agent antiadhérent, et, sur une surface inférieure, un revêtement (16) à base d'un agent adhésif. Sous le revêtement (16) adhésif se trouve une pellicule (18) comportant, sur sa surface supérieure, une antenne (20), et, connecté à cette antenne (20), un circuit intégré (22). Cette pellicule (18) comporte, sur sa surface inférieure, un revêtement (24) à base d'un agent adhésif sensible à la pression. Le circuit intégré (22) est complètement encapsulé dans une couche de protection flexible (26) en matière imperméable non conductrice, de préférence une matière pouvant être durcie aux UV, telle que du polyuréthanne.
