Weyerhaeuser has developed a process for manufacturing RFID-tagged cardboard, which it plans to license to International Paper and other firms. Admittedly, demand is low at the moment.
In 2005, Weyerhaeuser began developing a high-speed RFID label application process. Presently, a small number of Weyerhaeuser customers receive pre-tagged cardboard boxes that they utilize to track and trace product, either to comply with retailer mandates or to improve their own supply chain visibility. Using pre-tagged corrugate boxes saves these companies labor and infrastructure costs associated with applying RFID labels themselves, either by hand or through the addition of an RFID label printer-encoder-applicator on a packaging line.
Weyerhaeuser reportedly has created a process enabling it to apply RFID labels to a container's exterior, and to verify the inlay's functionality without slowing the corrugate manufacturing line.
