The present invention is to provide a packing bag with a RFID function, which comprises a bag body, two conductive films and a RFID chip. The metal layer includes a first slot formed at a position proximate to an edge of the bag body and is used as a slot antenna. A second slot is formed between the two conductive films, and has a size capable for fixing the pins on two corresponding sides of the RFID chip onto the two conductive films respectively. The two conductive films are fixed on an external surface of an insulating layer of the bag body at a position corresponding to the first slot, such that the two conductive films can be coupled to two feed-in points of the slot antenna respectively, and the RFID chip can receive and transmit electromagnetic signals through the slot antenna (or the metal layer) accordingly.
