Edge protectors (also called corner guards, edge guards, or angle boards) are essential packaging supports designed to safeguard products during shipping and storage. They provide critical reinforcement by distributing the pressure from straps, stretch wrap, or shrink film evenly across the edges of boxes, cartons, and palletized loads.

By preventing edge crushing, corner dents, and strap marks, edge protectors help maintain the integrity of both the product and the packaging. In addition to protecting individual items, they stabilize palletized loads, reduce the risk of shifting or toppling during transport, and improve overall load handling and stacking strength — making them an indispensable component of any professional shipping or warehousing operation.
