Cardboard Angle Boards: Heavy-Duty Edge Protectors for Pallet Shipping
29 July 2026
Cardboard angle boards protect pallet edges and spread strapping pressure when their size, placement and restraint method suit the shipment.
They are not a substitute for load testing or correct pallet restraint. Their value comes from protecting vulnerable corners and helping packaging components work together as a system.
What Are Cardboard Angle Boards?
Cardboard angle boards are rigid, L-shaped edge protectors positioned along carton or pallet edges. They can provide a bearing surface beneath strapping, reduce localised pressure on cartons and help maintain aligned vertical edges during handling.
Westside Packaging supplies cardboard angle boards in published lengths including 150 millimetres, 1 metre, 1.17 metres, 2.1 metres and 2.4 metres. Pack quantities vary by size, so buyers should confirm the most practical option for their load and packing volume.
How Should Angle Boards Be Selected?
Start with the pallet rather than the word “heavy-duty”. The board length and placement should reflect the load height, vulnerable edges, strapping path and handling method.
Confirm:
- pallet dimensions and overall loaded height;
- carton strength, weight and edge vulnerability;
- the number, type and position of straps;
- whether stretch film or another containment method is used;
- forklift, conveyor and warehouse handling conditions;
- expected storage duration and moisture exposure; and
- pack quantity and replenishment requirements.
Short protectors may suit isolated strap contact points, while full-height boards can protect longer vertical edges. The correct configuration depends on the actual shipment.
Do Angle Boards Make Double-Stacking Safe?
Not automatically. Angle boards do not prove that a pallet can carry another loaded pallet. Double-stacking depends on carton compression strength, pallet condition, weight distribution, unit-load design, storage duration and handling conditions.
Businesses should validate the complete pallet configuration before changing stacking practices. The National Transport Commission’s load restraint guidance explains the performance standards and practical considerations for restraining loads during road transport.
Avoid statements that angle boards “double storage capacity” or virtually eliminate crushing. Those outcomes require load-specific evidence and can create unsafe expectations.
How Do Angle Boards Work with Strapping?
Strapping applies tension to secure a load, but narrow contact points can mark or crush carton corners. Angle boards distribute that force across a wider surface. They can also create a cleaner edge for stretch film and reduce direct abrasion at exposed corners.
Westside Packaging’s overview of composite strapping options helps buyers compare related restraint materials. Compatibility, tension and application method still need to be assessed together.
Specify the Complete Pallet Protection System
Angle boards perform best when matched to the cartons, pallet, strapping, film and transport conditions. Choosing by price or length alone can leave critical edges unprotected.
Run a controlled packing trial before applying a new configuration across every shipment. Inspect strap marks, corner compression, movement and film condition after handling that reflects the real distribution route. Record the board size, strap tension and wrapping method so warehouse teams can reproduce the approved pack. This creates useful evidence for purchasing decisions and future damage investigations.
Review Westside Packaging’s packaging product range, then provide the pallet dimensions, load weight, carton configuration and current damage issue. A specific enquiry gives the supplier enough information to recommend a more defensible packaging combination.
