AI summary

A liner free label includes a substrate having first and second sides, a radio frequency identification (RFID) inlay on the substrate which includes a chip and an antenna, and an adhesive applied to at least a portion of the first or second side. The RFID inlay may be embedded within the adhesive, function as a sense mark, or be accompanied by a separate sense mark. The antenna may comprise a printed antenna, foil antenna, or a combination thereof. The RFID inlay may be purchased from an original equipment manufacturer (OEM) or include an OEM chip with a separately manufactured antenna. A roll of liner free labels includes multiple such labels with adhesive applied as a flood coating, discontinuous patches, continuous patches, or patterns. The labels may be separated by perforations. The technology combines the waste reduction benefits of liner free labels with the tracking capabilities of RFID technology.
