Strapping a few cartons together looks simple — until it's your first time and the buckle won't grip. This quick guide (with a 60-second video) walks you through how to use plastic strapping the easy way, plus the specs and tools you'll need to get a tight, secure strap every time.
What you'll need
- Plastic (poly) strapping in your chosen width and breaking strain
- Plastic or metal buckles/seals to lock the strap
- A tensioner and cutter (or scissors/snips for light jobs)
How to use plastic strapping in 5 steps
- Wrap the strapping around your items and make a loop at each end.
- Thread both loops into the bracing buckle and fold the locking arms over.
- Pull the loose ends to draw the strap tight and lock the arms in.
- Cut off the excess strapping.
- Repeat for a second strap (run it at 90° to the first for heavier loads).
Choosing the right strapping: breaking strain
Plastic strapping breaking strain ranges from about 95 kg up to 1,100 kg depending on the grade and width you choose. As a rough guide:
| Use case | Typical choice |
| Light bundling (cartons, print, light parcels) | Lighter-gauge poly strapping + plastic buckles |
| General warehouse & pallet loads | Heavier poly strapping + metal seals (crimped) |
| Very heavy / sharp-edged loads | Steel strapping (special order — ask us) |
Plastic vs metal buckles
Plastic buckles (shown in the video) are quick and tool-free — ideal for lighter bundling. For heavier loads, metal seals hold more tension but need a crimping tool to lock them. If you're strapping a pallet of stock, pair strapping with our stretch wrap for a fully secured load.
FAQ
What is plastic strapping used for?
Bundling cartons, securing goods to pallets, and closing boxes for transport — anywhere you need a strong, tamper-evident strap.
Do I need a tensioner?
For occasional light bundling you can hand-tension and use plastic buckles. For consistent, tight straps on heavier loads, a tensioner and cutter make the job faster and safer.
What's the difference between poly and steel strapping?
Poly (plastic) strapping suits most everyday loads up to ~1,100 kg breaking strain. Steel is for extreme loads or sharp edges — talk to us if you think you need it.
