Film breaks during wrapping Poor load containment Film not cutting or clamping

Film breaks during wrapping

Hits OEE: Availability

Symptoms: Film snaps mid-cycle, frequent stops and re-threads.

Pre-stretch or tension too high

Reduce pre-stretch/film force; tune for the film gauge.

Sharp load edges

Add edge protection; adjust corner handling.

Film quality or carriage rollers

Check the film spec and the pre-stretch rollers.

Prevention: Correct film-force settings, edge protection, carriage maintenance.

Poor load containment

Hits OEE: Quality

Symptoms: Loose loads, shifting in transit, damaged pallets.

Too few wraps or low force

Set wrap count and containment force; add top/bottom revolutions.

Wrong wrap pattern

Program a pattern suited to the load.

Pre-stretch not optimised

Increase pre-stretch for better cling and holding force.

Prevention: Validated wrap recipes, correct force, pre-stretch tuning.

Film not cutting or clamping

Hits OEE: Availability

Symptoms: Film tail not cut/clamped, film drags, cycle faults.

Cut-and-clamp fault

Check the cutter, heat element and clamp mechanism.

Timing or sensor issue

Verify the carriage home position and sensors.

Film wrap-around on rollers

Clean rollers; correct threading.

Prevention: Cut/clamp maintenance, sensor checks, correct threading.

Stop the same fault coming back

Recurring stretch wrapper stops usually trace to a cause you cannot see by hand. The partner we recommend is Fabrico: EU-built, so your production data stays in EU jurisdiction, with computer-vision true-cause of micro-stops, a closed loop from PLC-read OEE to an auto-routed work order, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness).
