A package includes a container (12) having a neck finish (14) and a closure (16) having a plastic shell with a skirt (18) externally secured to the container neck finish. A seal disk (24 or 24a) includes an electrically conductive layer (26) on a plastic substrate (28). The periphery of the plastic substrate is sealingly secured to the neck finish of the container. The conductive layer includes a circumferentially continuous outer periphery (30) overlying the periphery of the plastic substrate and an inner portion (32) structured as an rf antenna. An RFED tag (34) is electrically connected at least to the inner portion of the conductive layer. A liner disk (36) may be disposed between the closure and the seal disk separate from the seal disk. The closure skirt may have an internal bead (38) to engage the periphery of the liner disk and lift the liner disk off of the neck finish upon removal of the closure from the container neck finish.
