A package includes a container having a neck finish, and a closure having a plastic shell with a skirt externally secured to the container neck finish. A seal disk includes a metal layer on a plastic substrate. The periphery of the plastic substrate is sealingly secured to the neck finish of the container. The metal layer of the seal disk includes a circumferentially continuous outer periphery overlying the outer periphery of the plastic layer and an interrupted inner portion within said outer periphery. An RFID assembly includes and an RFID tag electrically connected to an antenna. The RFID assembly is captured between the seal disk and the plastic shell, and the interruptions in the inner portion of the metal layer of the seal disk reduce or eliminate interference in communication between the RFID assembly and external interrogation circuitry. A liner disk may be disposed between the seal disk and the RFID assembly. The closure skirt may have an internal bead to engage a periphery of the liner disk and lift the liner disk off of the neck finish during removal of the closure from the container neck finish.
