RFID Labels for Metal, Plastic, Cartons, and Liquid Products: A Practical Guide
RFID label performance changes significantly with the material and shape of the tagged item. A standard UHF RFID label that reads well on a cardboard carton may lose most of its range when placed directly on metal or near liquid. For a reliable deployment, the label construction, antenna, adhesive, mounting position, and test method must match the real product. RFID labels for cardboard and paper cartons Corrugated cartons and paper packaging are usually the simplest surfaces for UHF RFID. Standard paper or PET RFID labels can often provide stable performance when the antenna is kept flat and away from metalized printing, foil liners, and dense liquid products. Buyers should still test the label on a fully packed carton because the contents can change RF behavior. RFID labels for plastic products Plastic is not one uniform RF environment. The resin, wall thickness, curvature, surface energy, and product contents all affect the result. Flexible RFID labels work well on many flat pla...
