More Information
Summary:Transponder label is made up of antenna (8) and connected chip (9) on printable support layer (2). It has first adhesive layer (7) to affix label to item so that force required to remove label is more that the mechanical stability of the transponder support layer. When attempt is made to remove label from item, label is irreversibly distorted so RFID transponder is destroyed. Transponder consists of 20 to 250 microm thick polyester foil (2) with printed antenna (8) and chip (9) formed on foil upper side which is in contact with first hot melt adhesive layer (7). Transponder is placed on 57 microm thick separation paper, is partially coated with second hot melt adhesive paste (3) of 50 microm. Polyester foil has cut lines (5) to weaken mechanical stability. Cover layer is not adhered with the foil along and inside the cut lines. Cohesion and adhesion of heat melt adhesive and cover hot melt adhesive are selected so that if label is removed from item, foil remains on item at cut lines, rips along cut lines so antenna conductor path is destroyed and transponder is no longer functional.
