Patent ID: 8480000

Claim:
A packing bag with a RFID function, comprising: a bag body, comprising a metal layer, an insulating layer and a laminated layer; wherein an external surface of the metal layer is attached to an internal surface of the insulating layer, an internal surface of the metal layer is attached to an external surface of the laminated layer, corresponding edges of an internal surface of the laminated layer are sealed with one another to form the bag body, an accommodating space is defined in the bag body, a first slot is formed on the metal layer and at a position proximate to an edge of the bag body, and the first slot has a conformation for using the metal layer as a slot antenna; two conductive films, being separated by a second slot; wherein the two conductive films are attached to an external surface of the insulating layer and at positions that the second slot corresponds to the first slot and the two conductive films are coupled to two feed-in points of the slot antenna respectively; and a RFID chip, with a size smaller than each of the conductive films, and having pins disposed on two corresponding sides of the RFID chip and fixed onto the two conductive films respectively.
