These label holders differ in how they hold the labels. Our Economic Label Holders or EconoHolder feature a C-channel design for label insertion and are available with adhesive and magnetic backing. HOL·DEX label holders, on the other hand, are self-adhesive and function using a hook-and-loop mechanism.  Super-Scan label holders are our premium and most innovative holders that are available in all three formats - self-adhesive, magnetic, and hook-and-loop backings. You may choose the one that suits you best! These are designed for the bigger size labels and are made from sturdy matte-finished plastic to eliminate glare and improve barcode reading.
