Strapping machines (carton and pallet)
PP strap is usual for cartons, PET for pallets; semi-automatic, automatic and unmanned inline machines, with top press and corner boards as options.

Strapping machines tie cartons or whole pallet loads with plastic strap. Carton strappers mostly use PP strap: semi-automatic models are threaded by hand; automatic models have an arch, so the operator pushes the carton in and it is strapped at the touch of a button, and with a conveyor plus positioning, detection and interlocks they run unmanned. Pallet strappers mostly use stronger PET strap and run inline, strapping horizontally (against sideways shifting) or vertically (tying the load to the pallet); loose or compressible loads get a top press, and corner boards stop the strap cutting into cartons.
Typical uses
- Securing cartons in factories and e-commerce warehouses
- Bundling printed matter and textiles
- Pallet strapping for beverages, building materials, paper and appliances
- Final securing after palletizing and wrapping
How to choose
- Daily volume: semi-automatic for small, automatic or inline for large
- Whether it connects to a conveyor
- Maximum carton or pallet size: the arch needs a margin
- Choose the strap by load, tension and tension retention: loose or compressible loads usually take PET strap, with a top press where needed
- Horizontal strapping against sideways shifting, vertical to tie the load to the pallet
When it is not the right choice
- Very low volume: a battery hand tool is enough
- Steel coils and other heavy loads: assess load securing first and use a dedicated steel-strap or heavy-duty solution
- Fragile loads that need a top press: assess the press force first
Key figures
| Carton strapping speed | Semi-automatic about 3 s per strap; automatic about 1.5–2.5 s |
|---|---|
| PP strap | About 5–15 mm wide |
| Carton arch | About 650×500 to 850×600 mm |
| Pallet strap | PET, about 9–19 mm wide |
| Pallet strap tension | About 1,100–3,200 N |
| Pallet throughput | About 60–120 pallets/h, depending on horizontal or vertical strapping, number of straps and top press |
Figures are typical configuration ranges; exact specifications are set per project.
