MACHINE FILM TROUBLESHOOTING
Why machine stretch film breaks on a pallet wrapper
A broken web does not automatically mean the film is too thin. First identify where the break starts, then check the wrapper and the load under the same operating conditions. Change one variable at a time.

FIND THE BREAK POINT
Match the symptom to the first inspection.
Stop the wrapper safely and follow its lockout procedure before touching the carriage, rollers or moving parts. Record the roll lot and settings before making adjustments.
| Decision point | First checks | What to try next |
|---|---|---|
| Break at a pallet corner | Look for exposed nails, sharp cartons, overhang and a repeated break at the same point in the cycle. | Protect the edge or change the wrap path. Run a representative load again before increasing gauge. |
| Break inside the carriage | Inspect roller cleanliness, nicks, alignment, film threading and carriage condition according to the machine manual. | Correct the mechanical issue and repeat the same wrap program with the same film lot. |
| Break during acceleration or at the top/bottom | Check film tension, pre-stretch setting, turntable or arm speed, and the transition between wrap cycles. | Adjust one setting within the wrapper maker's limits; document breaks and applied-film weight after each change. |
| Breaks only with one roll or lot | Check roll damage, telescoping, edge defects, storage conditions and whether the current label matches the approved specification. | Isolate the suspect roll. Compare it with another roll under identical settings and retain the lot details for the supplier. |
This is a troubleshooting sequence, not a machine setting or a claim that a particular gauge will prevent breaks.
CONTROLLED RETEST
Decide whether the correction actually worked.
Use the same wrapper, pallet type and wrap pattern for a baseline and a retest. Record the number of breaks, rewraps, pallets per roll, applied film weight and whether the finished load stays stable. A trial that stops breaks but doubles film use may not be an improvement. The existing machine film trial checklist organizes these observations.
WHEN TO ASK FOR FILM SUPPORT
Send evidence, not just a gauge number.
Send the wrapper make and model, carriage type, current film label, roll lot, photographs of the break location and a short video of the cycle if available. Include pallet height, corners and any recent machine changes. Those details make a recommendation more useful than asking for a thicker roll without diagnosing the cause.
NEXT STEP
Compare film only after the wrapper is checked.
