| Light, compact cartons | Approximately 40 × 48 in (1,016 × 1,219 mm); up to 500 lb (227 kg) | Uniform, well-stacked cartons with little overhang | Short domestic shipment; limited handling and indoor storage | Polypropylene (PP) strap, typically 3/8–1/2 in (9.5–12.7 mm) wide | Manual tensioner and sealer, or a compatible combination tool; select seals sized for the strap | Usually two straps around the load and pallet, placed in opposite directions when the load shape permits | PP is generally suitable for lighter loads. Check that the strap edges do not crush cartons and that the pallet can be safely handled. |
| Medium-weight, stable cartons or bundled goods | Approximately 40 × 48 in (1,016 × 1,219 mm); 500–1,500 lb (227–680 kg) | Regular stack with moderate movement risk during loading or transit | Multi-stop road transport or routine warehouse handling | Polyester (PET) strap, commonly 1/2–5/8 in (12.7–16 mm) wide | Manual or battery-powered tensioner with a compatible sealer; use a tensioner rated for the selected strap | Two or more horizontal bands; add cross-banding where the stack could shift | PET generally retains tension better than PP and is often chosen for heavier unit loads. Determine strap strength from the load and handling plan, not weight alone. |
| Heavy, dense, or rigid unit load | Approximately 40 × 48 in (1,016 × 1,219 mm); 1,500–3,000 lb (680–1,361 kg) | Dense products, rigid cases, or loads with substantial movement forces | Long-distance transport, repeated transfers, or rough handling | High-strength PET strap, often 5/8–3/4 in (16–19 mm); strap grade and breaking strength must match the application | Powered tensioner or suitable pneumatic tool, plus compatible seals or a seal-less joint system | Multiple bands in both directions; use edge protectors where straps contact corners | Check pallet capacity, load restraint requirements, and tool specifications. Do not apply a generic tension value; excessive tension can damage the load or pallet. |
| Irregular, tall, or potentially unstable load | Any footprint; weight varies. Pay particular attention to tall loads or uneven weight distribution. | Mixed carton sizes, rounded items, narrow top layers, or uneven surfaces | Forklift handling, vibration, braking, or frequent transfers | PET strap is a common choice; select width and strength according to load geometry and the restraint plan | Kit with adjustable tensioning, compatible seals, corner protectors, and a dispenser suited to the strap coil | Use vertical and horizontal bands as appropriate; add stretch wrap or blocking when needed to control shifting | Banding alone may not stabilize an irregular load. Keep straps positioned to prevent slippage and avoid crushing vulnerable products. |
| Load exposed to outdoor storage or moisture | Any footprint and weight; assess both product and packaging sensitivity | Stable or moderately variable load requiring weather-aware packaging | Outdoor staging, humid conditions, or possible rain exposure | PET strap is commonly used; select a corrosion-resistant compatible seal or joint system | Manual or powered tool compatible with the chosen PET strap; store strap and tools dry when not in use | Band according to load stability; protect edges and keep banding clear of standing water where possible | Choose strap and packaging for the full exposure period. Moisture can affect packaging and some metal components; inspect bands before dispatch. |
| Very high restraint demand or specialized industrial load | Weight and dimensions determined by the shipment specification and risk assessment | Extremely dense, sharp-edged, or high-consequence cargo | Specialized freight, severe handling, or regulated transport conditions | Steel or high-strength PET may be specified; selection depends on the cargo, edges, and transport method | Dedicated tool and joint system rated for the chosen strap; trained operators and appropriate protective equipment | Follow the engineered load-restraint plan; use suitable edge protection and approved blocking or bracing | Do not select a kit by load weight alone. Confirm applicable transport rules and obtain a qualified restraint assessment where required. |
