Abstract

Sac d'emballage pourvu d'une étiquette RFID attachée pourvu : d'un corps en forme de sac formé par le scellement de parties périphériques d'éléments en forme de feuille qui se font mutuellement face, le corps comportant une région de réception pour recevoir un contenu à l'intérieur de celle-ci, et ayant un côté de coupe sur un premier côté de celui-ci ; et d'une étiquette RFID disposée dans le corps et ayant un motif d'antenne et un élément RFIC. Le corps comporte une région de coupe pour couper la région de réception, la région de coupe étant interposée entre une première ligne de région et une seconde ligne de région qui sont des lignes virtuelles s'étendant dans une direction croisant le côté de coupe. Le motif d'antenne de l'étiquette RFID comprend un premier élément d'antenne s'étendant de l'élément RFIC à la première ligne de région par l'intermédiaire de la seconde ligne de région, et un second élément d'antenne s'étendant de l'élément RFIC à la seconde ligne de région par l'intermédiaire de la première ligne de région, et constitue un motif d'antenne de type dipôle.
