3D Carton Overwrapper Shift Output & Mold Changeover Planner
Calculate net shift capacity across 10–180 BPM cellophane overwrappers after accounting for 20-minute mold changeovers and BOPP film roll splices.
How Multi-SKU Changeovers Affect Real Shift Output
In contract cosmetics and tea packaging, nominal BPM tells only half the story: running four 2,500-box SKUs in one 8-hour shift introduces three 20-minute mold swaps that consume 12.5% of clock time before counting film splices. Built under overwrapper selection and sizing and BOPP and cellophane film specs, use this planner to match machine class to real batch schedules.
Formula: Net Shift Cartons = [480 min − (Changeovers × Swap Minutes)] × Nominal BPM × 0.88 Run Availability.
Net 8-Hour Shift Output by Machine Tier & SKU Changeovers
Calculated net wrapped cartons per 8-hour shift (480 min) at 88% running availability:
| Overwrapper Tier (Nominal Speed) | 0 Swaps (Single SKU) | 2 Mold Swaps (25 min ea) | 4 Mold Swaps (25 min ea) | Recommended Daily Volume |
|---|---|---|---|---|
| Semi-Auto Electric (12 BPM) | 5,060 boxes | 4,850 boxes (10 min guide) | 4,640 boxes | 500 – 4,500 boxes/day |
| Linear Auto CW-230 (45 BPM) | 19,000 boxes | 17,020 boxes | 15,040 boxes | 5,000 – 18,000 boxes/day |
| Servo Cam FTBT-480 (80 BPM) | 33,790 boxes | 30,270 boxes | 26,750 boxes | 18,000 – 32,000 boxes/day |
| High-Speed Turret (140 BPM) | 59,130 boxes | 50,260 boxes (35 min) | Dedicated 1–2 SKU runs | 35,000 – 100,000+ boxes/day |

3D Overwrapping Engineering Notes
- Sequence Similar Dimensions Together: Schedule cartons that share W × H cross-sections back-to-back so operators only adjust length guides (5 minutes) instead of full folding plates.
- Roll Length Uptime Math: A standard 3,000-meter BOPP reel at 220 mm sheet cutoff yields ~13,600 cartons per roll—roughly 4.5 hours uninterrupted at 50 BPM.
- Dual-Machine Multi-SKU Split: Sometimes two 45 BPM linear overwrappers out-produce one 90 BPM machine when a plant changes carton sizes six times a day.
