Never Scrape Label Residue Again! Placards act as a permanent label holding surface. The one-time use labels quickly apply and remove with no sticky residue or messy overlapping. This product provides an efficient way to accurately identify and manage a variety of returnable/reusable assets, including containers, pallets and racks. Cardholders also allow for this as well. Used for Kanban and Kaizen systems once packaging has made it to the line.
