Proven Strategies to Reduce Line Downtime on Packaging Lines
May 4, 2026
The organization loses money every minute a packaging line sits idle. For plants running multiple SKUs with frequent changeovers, those minutes add up fast. This blog covers seven practical strategies that Septimatech's engineering & service teams often suggest to reduce line downtime. Some of these strategies include tracking and categorizing stoppages to upgrading guide rail systems and organizing change parts for faster format switches.
What is "Downtime" on Packaging Lines?
Line downtime in the packaging industry is generally defined as any period when a production line stops running product. Even short interruptions add up over a shift. A few 10-minute stops mean by the end of the week, you might be looking at hours of lost production. Tracking and categorizing downtime events is the first step toward reducing them.
On packaging lines, downtime falls into two categories: scheduled stops like maintenance windows and operator breaks, and unscheduled stops caused by equipment failures, jams, or quality issues.
Planned downtime happens on purpose. Preventive maintenance, format changeovers, and shift breaks all fall into this category. Because operations can schedule around planned stops, they're easier to manage.
Unplanned downtime is exactly as it sounds - un-intentional. Equipment failures, line jams, and unexpected quality rejects show up without warning and throw off the entire production schedule.
Common Downtime Reasons on Packaging Lines:
Worn change parts, aging machines such as fillers / cappers, and deferred maintenance all lead to unexpected breakdowns. When a filler, labeler, or capper goes down without warning, the entire line stops.
Machine & line changeovers are part of running multiple products, but they become a problem when they take too long or vary from one operator to the next without proper changeover solutions. Without standardized procedures, the same product changeover can vary dramatically from one operator to the next.
The line is not running when spending time searching for guide rails, timing screws, star wheels, or other change parts. On top of that, improperly stored parts can become damaged, leading to quality issues or additional delays once they're finally installed.
Well-designed equipment can still underperform when operators are not familiar with proper setup procedures. Incorrect adjustments, missed steps, and inconsistent techniques all contribute to extended changeovers and unexpected stoppages.
Why reducing packaging line downtime matters:
Every minute a packaging line sits idle has a ripple effect across the operation causing things like:
- Lost throughput
- Higher operating costs
- Reduced flexibility
Proven strategies that Septimatech recommends for reducing equipment downtime:
1. Track and categorize downtime events.
You can't improve what you don't measure. Logging every downtime event, and categorizing it by cause, reveals trends and can help you identify where the biggest opportunities are hiding. Common categories we have seen include mechanical failures, changeovers, quality holds, and material shortages. For example if changeovers account for 40% of your downtime, you know exactly where to focus your efforts.
Treating downtime as a key performance indicator changes how teams think about it. When operators and supervisors see downtime data regularly, they're more likely to take ownership of reducing it.
2. Implement a preventive maintenance schedule.
Reactive maintenance is almost always more expensive and disruptive than scheduled upkeep. According to NIH research, preventive maintenance delivers 48.5% lower unplanned downtime compared to reactive approaches. A preventive maintenance program involves regular inspections, lubrication, and part replacements based on runtime or calendar intervals.
The goal is catching wear before it causes failure. This approach won't eliminate every breakdown, but it significantly reduces how often unplanned stops occur and how severe they are when they do happen. Companies report achieving up to 45% reduction in equipment downtime through preventive maintenance programs.
3. Standardize changeover procedures.
When every operator follows the same sequence of steps, changeovers become faster and more predictable. Documenting procedures with visual aides removes guesswork and reduces variation between shifts. Septimatech makes sure that operators aren't left guessing by making some of the simplest changeover solutions on the market today.
SMED, which stands for Single-Minute Exchange of Die, is a lean manufacturing methodology designed specifically to minimize changeover time. The core idea is separating tasks that can be done while the line is still running from tasks that require a full stop, then streamlining both.
4. Train your operators on best practices.
Even the best procedures fail if operators aren't trained on them. Routine training ensures everyone understands proper machine operation, changeover sequences, and what to do when something goes wrong. When multiple team members can handle changeovers on different machines, the operation becomes less vulnerable to absences or shift changes.
5. Organize parts using a 5S storage solution.
5S is a workplace organization methodology built around five principles: Sort, Set in order, Shine, Standardize, and Sustain. Applied to change parts, 5S means dedicated storage locations, shadow boards, and labeled carts that make it obvious where every part belongs.
The payoff is immediate. Operators spend less time searching for tooling, and parts stay protected from damage between uses. Septimatech's changeover carts are designed specifically to organize, protect, and deploy change parts quickly and safely.
6. Invest in aftermarket changeover solutions.
Full line replacements aren't always practical or necessary. Aftermarket solutions, like timing screws, cap handling systems, bottle inverters, and adjustable guide rails, can dramatically improve changeover speed and reliability on existing equipment. Working with a partner like Septimatech that focuses specifically on existing machinery and equipment can uncover other potential problems and give a true picture of what your machines condition is today, not as you bought it.
