Key takeaways
- A high-speed packaging line only runs as well as its most-stopped machine.
- Micro-stops are the defining loss: jams, misfeeds, web breaks, register faults.
- Serial machines starve and block each other, so one short stop costs the whole line.
- This is the vertical where the hidden factory is largest.
If you want to see the hidden factory in its purest form, watch a packaging or converting line. Dozens of machines run in series at high speed, handling variable film, board and product. Each brief stop looks trivial, and together they make packaging one of the lowest-OEE, highest-micro-stop environments in all of manufacturing.
What's a good OEE in packaging?
We found no published OEE range for packaging alone with a stated method. The usual reference is 85% world-class (traced to Nakajima, Introduction to TPM, 1988), and published plant studies found average OEE of about 55% to 65% (sources: Ljungberg, 1998; Hedman et al., 2016); the more useful target is your own line's trend. What holds packaging lines back is structural: many machines in series mean the line only runs as well as its most-stopped link. Calculate your OEE →
The biggest losses in packaging & converting
| Loss | Why it's big in packaging | OEE factor |
|---|---|---|
| Micro-stops | Jams, misfeeds, mis-applies: dozens per hour, each cleared in seconds, none logged | Performance |
| Web breaks & splices | Film and paper web breaks stop the line; splicing and re-threading take minutes | Availability |
| Registration & print faults | Print register drift, vision rejects, label and seal defects | Quality |
| Changeovers | Frequent format, SKU and artwork changes; short runs amplify changeover share | Availability |
| Starvation & blocking | Upstream and downstream imbalance idles machines even when they're healthy | Performance |
The dominant loss is the micro-stop, and packaging is where it hides best: the numbers are so frequent that nobody can log them by hand, so they vanish into a vague performance gap.

One packaging shift, worked through
Illustrative numbers for a cartoner and case packer line, so you can check the math against your own shift. Planned production time is 450 minutes. The log records a 30-minute format changeover and 10 minutes of film and board reel changes: 40 minutes of downtime. The cartoner is rated at 120 packs a minute but runs at 110 to keep the glue and folding stable, and it stops about 135 times for 20 seconds each, which nobody logs.
| Step | Calculation | Result |
|---|---|---|
| Availability | run time 410 min (450 - 40) / 450 | 91.1% |
| Packs made | 365 running min (410 - 45 of micro-stops) x 110 a minute | 40,150 |
| Performance | 40,150 / 120 a minute / 410 | 81.6% |
| Quality | 39,650 good of 40,150 (500 check weigher and code rejects) | 98.8% |
| OEE | 91.1% x 81.6% x 98.8% | 73.4% |
The log explains 40 lost minutes. The line lost 119.6: 40 of changeover and reel changes, 45 of micro-stops, 30.4 of running below rated speed and 4.2 of rejects. Two thirds of the loss never reached the log, and the biggest single piece is the one everybody calls "just a jam".
Reason codes for a packaging line
A short list everyone uses beats a long one nobody does. A starting set:
- Changeover: format change, film or board reel change, label roll end
- Cartoner: carton jam, misfeed, glue fault
- Case packer and wrapper: case jam, film break, seal fault
- Starved or blocked: nothing from the filler, palletizer full
- Material: warped board, film tension, wrong leaflet
- Quality: check weigher reject, code or date print fault
Log them in the free OEE tracker and the downtime Pareto ranks them for you; the downtime log template does the same on paper.
What a camera shows on a packaging line
A stop code tells you the cartoner stopped, not why the carton jammed in the seconds before. Where cameras are fitted, Fabrico's camera-based OEE software syncs camera video with machine data, so you can replay the moment the line stopped. Cameras also catch short stops and a line that is switched on but not producing, the losses nobody writes down: in the shift above, that is the 45 minutes the log never saw.
What downtime costs in packaging
Packaging is usually the last step, so a stop here can back up everything upstream and put finished-goods shipments at risk. On high-throughput lines the lost-units number climbs fast, and material waste (broken web, mis-printed film) adds to it. Estimate your downtime cost →
How leading packaging plants cut the losses
- Measure micro-stops automatically: they are often the largest loss on packaging lines, and the hardest to log by hand.
- Get the true cause per machine (which station, what condition) to fix the real failure mode, not a symptom.
- Balance the line so healthy machines aren't starved or blocked.
Fabrico is built for exactly this: it records stops from the machine signal, micro-stops included, and where cameras are fitted the video of each stop sits next to its machine data so the team can review and confirm the cause.
Why is packaging OEE lower than other industries?
Serial high-speed machines plus variable materials produce frequent micro-stops, and the series arrangement means each one starves or blocks the rest. The compounding is what pushes OEE down.
Where should we start?
Reducing micro-stops. Because they are often large and rarely measured, finding and fixing their causes is often the best first step. See the six big losses →
Does this cover labelling, filling and end-of-line too?
Yes, fillers, cappers, labellers, case packers and palletisers share the same micro-stop and line-balance dynamics. (See also Food & Beverage.)
