Packaging bag with radio frequency identification capability and its manufacturing method

Abstract

The invention discloses a packaging bag with radio frequency identification capability and a manufacturing method thereof. The packaging bag includes a bag body, at least including a metal layer, an insulating layer and a bonding layer, and the outer surface of the metal layer is covered on the inner surface of the insulating layer. Above, the inner side of the metal layer is draped on the outer side of the bonding layer, and the corresponding edges of the bonding layer are sealed to form a bag body, and an accommodation space is formed in the bag body, and the metal layer is positioned adjacent to the edge of the bag body Open the first slit, the configuration of the first slit makes the metal layer as the slot antenna; two conductive films, the second slit is maintained between the two conductive films, and the two conductive films are fixed on the outer side of the insulating layer corresponding to the position of the first slit; radio frequency The size of the identification chip is smaller than the conductive film, and the two corresponding side pins of the radio frequency identification chip are fixed on the two conductive films. The invention uses the metal layer in the bag as the slot antenna of the radio frequency identification chip, saves the design and material cost of the traditional non-radio frequency identification tag, and can maintain good transmission performance at the same time.

Description

technical field [0001] The present invention relates to a packaging bag with radio frequency identification capability and its manufacturing method. The packaging bag mainly includes a metal layer, and a first slit is opened on the metal layer, so that the metal layer becomes a slot antenna (Slot antenna). The conductive film can be coupled to the two feeding points of the slot antenna, so that a radio frequency identification chip can be fixed on the two conductive films, so that the radio frequency identification chip can send and receive electromagnetic wave signals through the slot antenna. Background technique [0002] Press, radio frequency identification (Radio Frequency Identification, referred to as RFID) technology, also known as radio frequency identification tag (RFID tag), is a communication technology that allows an identification system (such as: reader, reader) to pass through electromagnetic wave signals , identify a specific target, and read and write relev...
