The compressible-load problem
Corrugated, paper and FMCG loads are bulky, irregular in height and highly compressible. Manual operators face an impossible choice: under-tension and the boxes shift and collapse in transit, or over-tension and the strap cuts into and crushes the bottom layers. Worse, as the stack settles and air escapes during transport, a strap that was correct at dispatch goes slack.
| Challenge | Manual / steel | ErgoPack 726X + PET |
|---|---|---|
| Crushing box corners | Common (over-tension by hand) | Avoided (exact preset tension) |
| Load shift / collapse | Common (under-tension) | Prevented (repeatable tension) |
| Settling in transit | Strap goes slack | PET recovers tension |
| Speed at peak | Bottleneck | Under 40s per pallet |
Exact digital tension calibration
The ErgoPack 726X removes the guesswork. Operators pre-set the exact tension for compressible loads — from as low as 400N — and the machine applies that identical force to every pallet, securing delicate corrugated and FMCG cartons without crushing them. A line-laser aligns the strap over the edge protectors every time so the force is spread, not concentrated on a corner.
Why PET, not steel, for compressible loads
Corrugated and paper stacks settle and lose height in transit. Rigid steel cannot follow that movement and goes slack, while PET elongates and recovers — keeping the load tight from the warehouse to the destination.
Continuous high-speed dispatch
Corrugation and print-finishing plants run on volume, and end-of-line strapping is where they bottleneck. The electronic ChainLance lets one operator route, tension and seal a pallet in under 40 seconds, clearing the loading dock far faster during peak hours. The GO and 700 add the same routing speed for facilities that prefer to keep their own sealing tools.

- How do you strap corrugated boxes to a pallet without crushing them?
- Use a machine with finely adjustable, repeatable tension. The ErgoPack 726X lets you set a precise lower tension (e.g. 400N) and applies it identically to every pallet, so stacks are secured without the strap cutting into box corners — especially when combined with edge protectors and PET strap that recovers tension as the load settles.
- Why is automated strapping better than stretch wrap for paper products?
- Strapping applies precise vertical tension that pulls paper stacks down onto the pallet, preventing sliding, while using a fraction of the material. Stretch wrap only binds horizontally and consumes large amounts of film.
- What strap is best for compressible loads that settle in transit?
- PET strap, because it elongates and recovers tension as the load settles, staying tight where rigid steel would go slack. Applied at a calibrated lower tension on the ErgoPack 726X, it secures compressible loads without crushing.
