Preventative Maintenance in Corrugated Manufacturing: How Smart Facilities Reduce Downtime, Improve Safety, and Extend Equipment Life

Corrugated manufacturing environments are among the most demanding production settings in any industry. Heat, dust, starch, adhesives, fiber buildup, vibrations, and constant motion all converge to place heavy strain on equipment, infrastructure, and personnel. Because these facilities run at high speed - often around the clock - even small issues can quickly escalate into major operational disruptions.

Preventative maintenance isn’t just recommended in corrugated environments; it is essential. Corrugators, slitters, glue machines, stackers, conveyors, and material-handling systems all rely on precise calibration, routine cleaning, and ongoing inspection to operate safely and efficiently. When equipment is allowed to run until failure, facilities face longer outages, higher repair costs, lost production hours, and increased safety risks.

Kelly Industrial Services has forty years of experience inside corrugated plants across the U.S. - from small regional operations to high-volume integrated facilities. Our preventative maintenance programs help corrugated manufacturers reduce unplanned downtime, extend equipment lifespan, and maintain cleaner, safer, more reliable production environments. This guide explains what preventative maintenance looks like in corrugated operations, why it matters, and how facilities can use the right strategies to protect their equipment and productivity.

What Makes Corrugated Manufacturing So Tough on Equipment

Few industrial environments combine as many wear factors as corrugated plants. Corrugators run at high temperatures, producing constant waves of steam, heat, and humidity. Adhesives create sticky buildup on machinery. Paper dust and fibers move through the air and settle onto every surface, from the rafters down to the production floor.

These unique conditions create three major challenges:

Heat & humidity stress

Corrugators and glue machines produce high temperatures and moisture, which accelerate corrosion, coating breakdown, and equipment fatigue.

Dust, fiber, and starch accumulation

Airborne fibers settle on machinery, conveyors, rafters, walls, and structural steel. Adhesives and starch trap dust, creating thick buildup around production equipment.

Constant abrasion and vibration

Rotating equipment, rollers, slitters, and conveyors produce micro-movements that wear down components over time.

Because these conditions worsen gradually, many facilities don’t see the full impact until equipment performance declines, alignment shifts, or unplanned breakdowns occur.

Preventative maintenance stops these problems before they start.

The Role of Preventive Maintenance in Corrugated Production

Preventative maintenance (PM) in corrugated manufacturing is a structured, ongoing approach to maintaining equipment and facility infrastructure. It focuses on:

• reducing unplanned downtime
• improving equipment reliability
• lowering maintenance costs
• extending the lifespan of critical components
• preserving safety for operators and maintenance teams
• decreasing fire hazards and contamination
• supporting regulatory and customer audit requirements

Rather than waiting for something to fail, PM programs identify early warning signs and correct them while equipment is still functioning - long before repairs become urgent, expensive, or production-stopping.

Kelly Industrial Services works directly with corrugated maintenance managers, safety teams, and production supervisors to build preventative maintenance plans around the unique demands of each line and facility.

How Buildup Impacts Corrugated Equipment Performance

In corrugated facilities, the biggest enemy of performance is often the debris you don’t see. Dust and fibers fall from ceilings and rafters onto equipment. Adhesives harden in corners. Starch dries onto surfaces and traps additional contaminants. Even small amounts of buildup cause issues like:

• poor heat transfer
• misalignment of rollers
• uneven corrugation
• web breaks
• glue application problems
• jams on conveyors
• premature wear on bearings and motors
• overheating from restricted airflow

This buildup also increases fire risks significantly - especially when high temperatures meet combustible paper dust.

Preventative maintenance focused on cleaning, degreasing, and debris removal is one of the most effective ways to maintain performance and reduce hazards.

Cleaning as a Core Part of Preventative Maintenance

Cleaning is not separate from preventative maintenance - it is the foundation of it. Corrugated equipment cannot perform at its best when covered in dust, fibers, starch, or adhesive residue.

Preventative cleaning includes:

• machinery cleaning
• conveyor cleaning
• glue machine cleaning
• dry ice blasting of sensitive components
• pressure washing (in approved areas)
• manual scraping and degreasing
• rafter and structural steel dust removal
• high-reach vacuuming
• floor and wall cleaning
• inspection cleaning during shutdowns

Kelly Industrial Services incorporates industrial cleaning directly into PM strategies because clean equipment is:

• easier to inspect
• easier to maintain
• safer to operate
• less prone to heat stress
• less vulnerable to breakdown

Industrial cleaning is preventative maintenance - and in corrugated plants, it plays an outsized role in reliability.

Preventative Maintenance Tasks That Protect Corrugators

Corrugators are the heart of the plant - and also the machines most affected by neglect.

Preventative maintenance focuses on:

Thermal systems

Removing debris from heat plates, steam systems, and hot zones prevents warping and uneven bonding.

Drive systems

Keeping motors, gearboxes, and bearings clean reduces friction, overheating, and premature failure.

Guides and alignment systems

Dust-free alignment components mean fewer web breaks and fewer sheet quality issues.

Adhesive systems

Cleaning glue pans, applicators, and transfer rollers prevents uneven application and jams.

Rollers and belt systems

Debris-free rollers maintain proper flute formation and sheet consistency.

Kelly’s technicians clean components thoroughly, making inspections easier and reducing the chance of mid-run failures.

Why Shutdown Season Is the Best Time for Preventative Maintenance

Corrugated facilities often operate continuously, meaning shutdown windows - even small ones - offer the best opportunity for deep preventative maintenance.

Shutdown PM includes:

• full corrugator cleaning
• overhead and rafter cleaning
• structural steel cleaning
• dry ice blasting on sensitive machinery
• adhesive and starch removal
• machinery degreasing
• floor and wall cleaning
• support equipment cleaning (stackers, slitters, conveyors)
• painting or coating touch-ups
• safety marking refreshes

Kelly’s teams are trained to mobilize quickly during these windows, maximizing productivity while minimizing downtime.

How Preventative Maintenance Improves Safety in Corrugated Facilities

Corrugated environments carry inherent risks due to heat, dust, noise, and heavy equipment. Preventative maintenance directly improves safety by:

• reducing combustible dust hazards
• preventing slip-and-fall risks from floor debris
• improving visibility around equipment
• limiting overheating and equipment fires
• reducing unexpected mechanical failures
• supporting smoother operator workflow
• maintaining walkway and equipment boundary striping

Safety and maintenance are inseparable - clean, well-maintained equipment is safer equipment.

Building a Preventative Maintenance Culture on the Plant Floor

The best preventative maintenance programs don’t just live in a spreadsheet or CMMS system - they live in the habits of the people running the equipment every day. In corrugated manufacturing, operators are often the first to spot changes in sound, heat, vibration, sheet quality, or glue behavior. When they feel empowered to speak up and trained to recognize early warning signs, issues get addressed long before they turn into breakdowns.

A preventative maintenance culture means:

• operators see cleaning as part of running the machine, not as a separate task
• supervisors make time for inspections during shifts instead of pushing them to “someday”
• maintenance teams and production teams communicate openly about small changes and recurring issues
• leadership sees PM not as a cost center, but as an investment in uptime and safety

Kelly Industrial Services often becomes an extension of this culture by handling the heavy cleaning and shutdown work, while in-house teams manage daily tasks and inspections. Together, that partnership helps facilities maintain a high standard without overloading internal staff.

The Role of Documentation and PM Standardization

In many corrugated plants, maintenance knowledge lives inside a few experienced technicians’ heads. That works - until someone retires, changes roles, or is unavailable during a critical outage. Standardizing and documenting preventative maintenance is one of the simplest ways to reduce risk and create consistency.

Strong documentation includes:

• written PM procedures for each key asset
• visual references for what “clean” and “acceptable” looks like on critical components
• checklists that combine cleaning, inspection, and adjustment steps
• logs that track when machines were last cleaned, inspected, and serviced
• simple ways for operators to report issues and confirm completion of tasks

When Kelly supports preventative maintenance, we frequently work from or help inform these standards. Our crews follow plant-specific procedures, then provide feedback and observations that help refine what should be included in future PM cycles.

Integrating Inspection with Cleaning

One of the most overlooked advantages of industrial cleaning in corrugated environments is how it improves inspection quality. It’s almost impossible to thoroughly inspect bearings, rollers, drive systems, or fasteners if they’re buried under layers of dust, starch, and adhesive. Cleaning and inspection are not two separate activities - they’re two halves of the same process.

When equipment is properly cleaned:

• small cracks, leaks, or misalignments are easier to spot
• loose hardware and worn components stand out visually
• early signs of corrosion or paint failure become obvious
• oil leaks, air leaks, and glue drips can be traced to their true source
• inspectors can work faster and more confidently

Kelly’s work often reveals conditions that weren’t visible before we started. We clean down to the true surface, then plant maintenance teams can perform inspections with clarity instead of guessing what’s happening beneath the buildup.

Using Data and Metrics to Improve Preventative Maintenance

Corrugated facilities with strong preventative maintenance programs don’t just perform tasks - they measure outcomes. Data helps plants understand whether PM is actually reducing downtime, improving speed, and stabilizing quality.

Useful metrics include:

• unplanned downtime hours per month
• number of PM-related work orders completed on time
• repeat failures on the same machine or component
• mean time between failures (MTBF) on critical assets
• scrap and defect rates tied to mechanical issues
• average line speed vs. target speed

When these metrics trend in the right direction, it’s a sign that preventative maintenance is working. When they don’t, it’s an indication the program needs adjustment - perhaps more frequent cleaning in specific areas, or deeper inspection of components that keep failing. Kelly’s role is to support the physical side of that improvement, while plants use their own production data to validate and guide the PM strategy.

Common Preventative Maintenance Mistakes in Corrugated Plants

Even well-intentioned corrugated facilities fall into patterns that undermine their preventative maintenance efforts. Recognizing these patterns is the first step in correcting them.

Common mistakes include:

• treating cleaning as a cosmetic job, not as a performance and safety task
• skipping overhead and structural cleaning because it’s “out of sight”
• relying exclusively on reactive work orders issued after failures
• pushing shutdown work off “one more quarter” until it becomes a crisis
• focusing only on the corrugator and ignoring support equipment and conveyors
• failing to prioritize adhesive and starch removal, which often causes the thickest buildup

Kelly frequently partners with facilities that are ready to break these patterns. By bringing in a qualified external team to handle heavy cleaning and support PM, plants can reset their baseline and restart on a stronger footing.

How Preventative Maintenance Supports Customer Expectations

Corrugated manufacturing doesn’t operate in isolation - it’s part of a larger supply chain. Customers increasingly expect consistent lead times, fewer quality issues, and stability in their packaging supply. When preventative maintenance is neglected and breakdowns increase, customers feel that instability quickly.

Preventative maintenance supports customer expectations by:

• keeping line speeds predictable and steady
• reducing the number of quality-related rework runs
• preventing last-minute order delays due to unplanned outages
• supporting certifications or audits tied to quality and cleanliness
• enabling plants to commit to delivery schedules with confidence

When equipment runs reliably, corrugated facilities are better positioned to grow with their customers instead of constantly catching up from the last outage.

The Financial Case for Partnering Externally on Preventative Maintenance Support

Many corrugated facilities question whether to rely solely on in-house staff or bring in an external partner for parts of their preventative maintenance strategy. The financial argument for support often becomes clear once they compare the true costs of trying to do everything internally.

Internal-only approaches can lead to:

• maintenance teams stretched thin between emergency repairs and PM tasks
• cleaning work getting pushed aside in favor of urgent breakdowns
• shutdowns that don’t accomplish everything on the work list
• PM tasks skipped because “we didn’t have enough people this time”

By contrast, when Kelly supports PM efforts:

• plant maintenance teams can focus on high-skill mechanical and electrical work
• heavy cleaning, debris removal, and structural work are handled efficiently
• shutdown windows are used more effectively
• more items on the PM list are completed in less time

The result is a more complete preventative maintenance cycle - without requiring the plant to increase headcount or pull technicians away from critical repair work.

Designing a Long-Term Preventative Maintenance Roadmap

The most successful corrugated facilities don’t treat preventative maintenance as a one-time initiative - they design a roadmap that extends several years into the future. That roadmap doesn’t need to be rigid, but it should outline:

• which assets are most critical and must never be neglected
• when major cleanings and shutdown PMs will occur
• how often rafters, structures, floors, and machinery will be deep-cleaned
• when major coating, painting, or resurfacing will be addressed
• how PM will adapt as new equipment is installed or lines are reconfigured

Kelly Industrial Services often participates in these conversations as a planning partner. By understanding the plant’s long-term goals and capital plans, we can help align cleaning and maintenance support so that the facility stays ahead of wear instead of chasing it.

Preventative Maintenance Reduces Energy Waste

Corrugated equipment must operate efficiently to maintain production speed and quality. When machines are dirty or poorly maintained:

• steam energy must work harder
• motors pull more amperage
• adhesives do not apply evenly
• heat systems fluctuate
• friction increases
• fans and blowers run inefficiently

These inefficiencies are expensive over time.

When Kelly performs preventative cleaning and maintenance support, many facilities see measurable reductions in energy consumption - simply because machines no longer fight against debris, heat, and drag.

The Cost of Reactive vs. Preventative Maintenance

Corrugated maintenance teams already know the pain of reactive maintenance - the emergency breakdowns, the interrupted orders, the after-hours equipment failures, the parts that aren’t in stock.

But the cost difference is often misunderstood.

Reactive maintenance is always more expensive because it includes:

• emergency labor
• rush parts
• lost production hours
• extended shutdowns
• product defects
• increased safety risks

Preventative maintenance is always cheaper because it focuses on:

• smaller, predictable repairs
• early intervention
• planned scheduling
• consistent performance
• long-term asset health

Kelly helps corrugated facilities shift from reactive mode to preventative mode - and the cost savings are substantial.

Planning a Preventative Maintenance Schedule That Fits Corrugated Production

Corrugated plants don’t all run on the same schedule, and preventative maintenance must adapt to the facility’s production rhythms.

A strong PM schedule includes three layers:

Daily & weekly tasks

Operator-based cleaning, lubrications, and quick inspections.

Monthly cleaning & inspection

Deep cleaning of key components, debris removal, and mechanical checks.

Quarterly or semi-annual shutdown PM

Full facility cleaning, equipment maintenance support, structural cleaning, painting touch-ups, safety marking refreshes.

Kelly builds PM schedules based on the facility’s:

• production output
• equipment age
• condition of surfaces
• safety needs
• seasonal shutdown windows
• historical breakdown patterns

Every corrugated plant is different - and every PM plan should be too.
