Paper Corner Boards — Strength Where Cartons Fail
A paper corner board (also called an edge protector, edge board or angle board) is a rigid L- or U-shaped profile made from multiple layers of kraft paper and core paper, laminated under high pressure and heat. Placed on the edges and corners of cartons, pallets and bundled goods, it distributes strapping and stacking forces that would otherwise crush the package.

What GuardP Corner Boards Do for Your Shipment
- Prevent transit damage — protect the most impact-prone part of any carton: its corners and edges.
- Raise stacking strength — turn loose cartons into a stable, stackable unit.
- Enable tighter strapping — the board acts as a skeleton between steel or PET strapping and your product.
- Replace wood — lighter, cleaner, cheaper and 100% recyclable; no ISPM-15 fumigation required.
