Chipless RFID-enabled liner free labels and rolls of liner free labels

Abstract

A chipless RFID-enabled liner free label includes a substrate with an RFID antenna on the substrate and adhesive applied to the same side. The RFID antenna may be purchased from a third party, printed with conductive ink, formed from transferred conductive foil, or created as a combination of printed ink and foil. The adhesive may be flood coated or applied in discontinuous and/or continuous patches or patterns. The labels may include printed sense marks, or the antenna itself may function as a sense mark. A roll of such labels provides waste reduction benefits through elimination of the liner while maintaining RFID functionality without requiring chips. This technology in a roll format offers a cost-effective alternative to traditional chip-based RFID labels while preserving tracking capabilities.
