Process Optimization for the Packaging Industry
Packaging lines run at high speeds with frequent format changes. Carton erecting, filling, sealing, labeling -- each station must synchronize perfectly. Leanshift helps packaging operations reduce changeover losses and maximize line efficiency.
Challenges
Frequent format changeovers
Multiple SKUs per shift mean constant format adjustments. Every changeover minute is lost output.
Line synchronization issues
Speed mismatches between stations cause micro-stops, jams, and quality defects that are hard to trace.
Short production runs
Customer demand for smaller lot sizes increases the ratio of non-productive to productive time.
Packaging material waste
Film, carton, and label waste from setup, misalignment, and defects directly impacts cost per unit.
Relevant KPIs
Typical Process Example
Observe a full changeover
Record every activity from last good pack to first good pack of the next format with the stopwatch.
Categorize time losses
Muda analysis separates mechanical adjustment, material loading, trial runs, and waiting for QC approval.
Externalize preparation
SMED: pre-stage format parts, pre-thread film, pre-print labels while the current job still runs.
Standardize adjustment settings
Create visual setting sheets with photos and measurements for each format. Eliminate trial-and-error.
Verify improvements
Measure changeover times again. PDCA coaching ensures the new standard is followed consistently.

Frequently Asked Questions
How does Leanshift handle high-speed packaging lines?
The stopwatch captures changeover and setup activities -- not machine-speed cycle times. For line efficiency, focus on the time between runs and the losses during start-up.
Can we track OEE per packaging line?
Yes. Record availability losses (changeovers, breakdowns), performance losses (reduced speed, micro-stops), and quality losses (rejects) to calculate true OEE.
What about co-packing operations with many customers?
Co-packers benefit the most from SMED because changeover frequency is extremely high. Leanshift helps you build standardized changeover procedures that work across your customer portfolio.
