In today’s coating and converting industry, manufacturers face growing pressure to deliver consistent quality while improving productivity and controlling costs. Particularly in film coating and flexible packaging applications, challenges such as coating weight variations, process instability, scrap and rework can significantly impact profitability.
Despite regular quality checks and laboratory testing, many manufacturers struggle to identify the root causes of these issues. The reason is often simple: they lack visibility into what is happening throughout the production process. Companies such as German machine builder Mahlo are helping manufacturers address this challenge by providing greater insight into production performance in real time.
What Happens Between Quality Checks?
Most coating operations still rely heavily on offline measurements and laboratory inspections. While these methods remain essential, they provide only isolated snapshots of production performance.
Between measurements, process conditions can change considerably. A coating weight deviation that develops over a short period may affect large volumes of material before it is detected. By the time operators become aware of the issue, raw materials, production time and resources may already have been lost.
This creates a blind spot. Manufacturers know the quality status at selected inspection points but often have limited insight into what happens between them. As a result, process variability frequently remains hidden until it becomes an expensive problem.
The Business Cost of Limited Visibility
When variations cannot be identified immediately, manufacturers often compensate by applying wider safety margins. In coating applications, this can mean overcoating to ensure specifications are consistently achieved. While effective as a safeguard, it also increases raw material consumption and operating costs.
At the same time, undetected variability contributes to scrap, rework, customer complaints and reduced efficiency. Even when finished products meet specification, hidden fluctuations may be preventing the process from operating at its full potential.
From Reactive Quality Control to Proactive Process Management
A more effective approach is continuous inline measurement.
Rather than relying solely on periodic inspections, inline quality monitoring provides real-time visibility into process conditions throughout production. Deviations can be detected immediately, enabling operators to react before minor variations become major quality issues.
This shifts quality management from a reactive activity to proactive process control.
Continuous visibility allows manufacturers to understand process behavior, identify trends and maintain tighter control over production parameters. The result is improved product consistency, more stable production and better utilization of materials and equipment.
Solutions such as Mahlo’s Qualiscan QMS help transform process data into actionable insight. Measuring parameters such as coating weight, basis weight, moisture or thickness provides transparency and therefore enables more informed operational decisions.
Case Example: Improving Stability Through Continuous Monitoring
One of Mahlo’s customers, a manufacturer of coated film products, experienced recurring coating weight variability that was difficult to track using traditional quality checks. While offline measurements confirmed occasional issues, they provided limited information about when deviations occurred.
After implementing continuous quality monitoring, operators gained immediate visibility into process variations and could make corrections during production rather than after the fact.
The result was improved process stability, more consistent coating quality and reduced waste. Just as importantly, the manufacturer gained a better understanding of the production factors influencing product quality.
The experience demonstrated a simple truth: when operators can see variations as they occur, they can control them far more effectively.
Turning Data Into Better Decisions
For decades, Mahlo has supported manufacturers with solutions designed to improve process transparency and production performance. The company’s Qualiscan QMS provides continuous visibility into critical quality parameters, helping coating and converting manufacturers gain greater control over their processes.
Supported by a broad portfolio of sensor technologies for different coating and converting applications, the system helps improve process stability, reduce waste and optimize resource utilization.
More importantly, Mahlo’s role extends beyond supplying measurement technology. As a process optimization partner, the company helps customers convert production data into practical improvements that support quality, efficiency and long-term competitiveness.
Visibility Is the Foundation of Improvement
As quality requirements continue to increase across the coating and converting industry, process visibility is becoming a competitive advantage.
Manufacturers cannot improve what they cannot see. Continuous measurement provides the transparency needed to reduce variability, improve consistency and operate more efficiently. By turning real-time process data into actionable insight, manufacturers can move from detecting problems to preventing them. The result is better quality, lower waste and more stable production performance.
