Use PP (polypropylene) strapping for light-to-medium bundling — cartons, parcels, trays and print — where cost and speed matter. Use PET (polyester) strapping for medium-to-heavy palletised and export loads that need higher tension and retained holding force. PP tops out around ~188 Kgf; PET reaches up to ~1,400 Kgf.
| Factor | PET Strapping | PP Strapping |
|---|---|---|
| Break strength | Up to ~1,400 Kgf | Up to ~188 Kgf |
| Retained tension | Excellent on heavy/settling loads | Good for light loads, relaxes over time |
| Typical load | Medium to very heavy | Light to medium |
| Sealing | Friction weld / seals / buckles | Heat seal (machine) / manual |
| Cost | Higher per kg, steel alternative | Most economical |
| Best for | Pallets, bricks, timber, coils, export | Cartons, parcels, trays, magazines |
Choose PP for fast, economical bundling of light-to-medium goods. Step up to PET when loads are heavier, need to survive long transit, or when you're replacing steel. Many buyers stock both — PP for cartons, PET for pallets and export.
