| 1. Light-duty hand-buckle kit | Polypropylene (PP), about 9 mm | Approximately 100–250 lb (45–113 kg) | Small cartons and light parcels, commonly under about 25 lb (11 kg) | Reusable or single-use plastic buckles; strap is tensioned by hand | PP strap coil, plastic buckles, cutter, and dispenser or carry box | Low-cost and simple to use without a powered tool | Hand tensioning is slower and less consistent than tool-assisted strapping |
| 2. General-purpose hand-buckle kit | PP, about 12 mm | Approximately 250–400 lb (113–181 kg) | Everyday cartons and bundled parcels, commonly about 20–60 lb (9–27 kg) | Plastic buckles or metal seals, depending on the kit | Strap coil, buckles or seals, cutter, and manual tensioner | Versatile width for routine parcel packing | Actual joint strength depends on buckle or seal type and correct threading |
| 3. Heavy-duty PP manual kit | PP, about 15 mm | Approximately 400–600 lb (181–272 kg) | Large cartons and heavier bundled parcels, commonly about 40–100 lb (18–45 kg) | Metal seals applied with a compatible sealer, or compatible buckles | Wider PP strap, tensioner, sealer where required, cutter, and dispenser | Wider strap can provide more capacity than light-duty PP configurations | PP can lose tension over time and is not a substitute for a rated load-restraint system |
| 4. Light-to-medium PET hand-tool kit | Polyester (PET), about 12 mm | Approximately 600–900 lb (272–408 kg) | Heavier cartons and compact loads where lower strap stretch is useful | Metal seal or friction-weld joint, depending on the tool | PET strap coil, manual tensioner, compatible sealer, and cutter | PET generally retains tension better than PP and has good resistance to weathering | Tools and seals must match the strap width and thickness |
| 5. Medium-duty PET kit | PET, about 16 mm | Approximately 900–1,400 lb (408–635 kg) | Heavy cartons, grouped parcels, and palletized shipments | Metal seal or friction-weld joint | 16 mm PET coil, high-leverage tensioner, sealer or combination tool, and dispenser | Higher-strength option with less risk of sharp edges than steel strapping | Requires more tool effort than narrow, light-duty strap |
| 6. Corded polyester hand kit | Corded polyester, commonly about 13–19 mm | Varies by grade and construction; often specified by the supplier rather than by width alone | Irregular, bulky, or heavier packages and bundles | Friction buckle or wire buckle | Corded strap coil, compatible buckles, tensioner, and cutter | Flexible strap conforms well to uneven surfaces and is easy to handle | Strength varies substantially by cord construction; check the rated system strength |
| 7. Woven polyester buckle kit | Woven polyester, commonly about 16–19 mm | Varies by grade and construction; confirm the manufacturer’s rated strap strength | Heavy or irregular bundles that need a flexible, non-metal strapping option | Metal or high-strength polymer buckle | Woven strap, compatible buckle, tensioner, cutter, and portable dispenser | Flexible and comparatively gentle on many package surfaces | Buckle selection and correct threading strongly affect joint performance |
| 8. Steel-strapping manual kit | Steel, commonly about 12.7 mm wide; thickness varies | Highly grade- and thickness-dependent; roughly 1,500–2,500 lb (680–1,134 kg) for some common configurations | Very heavy or rigid loads, generally beyond routine parcel-carton use | Metal seal applied with a compatible sealer | Steel coil, tensioner, sealer, cutter, and protective handling equipment | High strength and low stretch for demanding applications | Sharp edges, recoil hazards, and corrosion risk require careful handling and training |
| 9. Semi-automatic PP kit | PP, commonly about 9–15 mm | Depends on strap grade and width; use the strap supplier’s specification | Repeated carton strapping at a packing station | Heat-sealed or friction-welded joint, depending on the machine | Semi-automatic strapping machine, compatible strap coil, and spare wear parts | Improves speed and consistency for regular packing volumes | Requires power, a fixed work area, maintenance, and machine-compatible strap |
| 10. Battery-powered PET combination-tool kit | PET, commonly about 12–16 mm | Depends on strap grade, width, and tool settings; verify the rated specification | High-volume packing or palletized parcels where portability and repeatable tension are important | Tool-generated friction weld; some systems use seals | Battery tensioning and sealing tool, charger, battery, PET strap, and cutter if not integrated | Portable operation with faster, more repeatable cycles than manual tensioning | Higher initial cost; battery, tool, strap width, and strap thickness must be compatible |
