Reduce damage rates and returns by reinforcing vulnerable areas and stabilizing loads.
Improve pallet integrity to withstand stacking, vibration, and strap or stretch wrap tension.
Enhance unboxing and product presentation by minimizing scuffs and corner crush.
Lower total landed cost by cutting re‑shipments, RMAs, and claim administration.
Edge and corner reinforcement are the first line of defense for cartons and pallet loads.
Use edge protectors to distribute pressure from strapping, protect carton edges from crush, and create a stable surface for stacking. They’re ideal for unitized loads, fragile carton edges, and products with high point‑loads beneath the strap.
Corner board adds vertical strength, protects corners from impact, and helps maintain straight, stackable edges during stretch wrapping. Common sizes and leg lengths are available—tell us your dimensions, load weight, and wrap/strap method, and we’ll match options.
Foam inserts protect sensitive parts and finishes by absorbing shock and preventing internal movement inside the carton. Whether you need simple pads or complex cavities, we can source foam inserts that fit your geometry and pack‑out. Share drawings, target dimensions, or a sample, and we’ll recommend options and minimums.
Dunnage bags are inflatable cushions placed between pallets or within trailers/containers to prevent lateral movement in transit. They help stabilize mixed loads, reduce freight claims, and speed loading by filling irregular gaps.
Build the right combination for your application:
Edge protectors to distribute strap tension and prevent edge crush
Corner board for vertical reinforcement and pallet stability
Foam inserts to immobilize parts and protect finishes
Dunnage bags for void fill and inter‑load bracing
Complementary materials like bubble and cushioning: Bubble Wrap & Cushioning
If you don’t see what you need, we specialize in sourcing hard‑to‑find protective packaging supplies. Ask about sizes, materials, and lead times.
Assess your failure modes: corner crush, abrasion, vibration, or top‑load.
Reinforce the weakest points with corner board or edge protectors.
Immobilize the product with foam inserts and correct dunnage strategy.
Unitize properly: match stretch wrap pattern, film gauge, and strap placement.
Test and iterate: perform drop/tilt checks and review claim data.
Maintain stock with reliable replenishment. Our VMI programs can help reduce stockouts and over‑ordering: Vendor ‑ Managed Inventory (VMI).
Common questions about our protective packaging supplies.
Corner board reinforces carton and pallet corners, distributes top‑load, and protects edges from impact and strap or stretch wrap pressure. It also helps maintain straight, stackable corners for stable pallets.
There’s no single best option. For heavier or mixed pallets, a combination of corner board (vertical strength), edge protectors (strap distribution), and dunnage bags (lateral bracing) is often effective. Share load specs so we can recommend a tested solution.
We can source custom foam inserts through our supplier network. Provide a drawing, dimensions, or a sample part, plus target quantities, and we’ll advise on materials, tooling (if any), and lead times.
Dunnage bags are inflatable cushions used between loads inside trailers or containers to brace freight, prevent shifting, and reduce damage from vibration and sudden stops.
Strengthen corners with corner board, protect edges with edge protectors, immobilize parts using foam inserts, and brace pallets with dunnage bags. Validate with a pack test and adjust film/strap settings.
