Same sealing line. Predictable seal quality. Higher consistency.
Heat sealing is a critical step in food and FMCG packaging, where package integrity directly affects product safety, shelf life, leakage risk, and customer experience. A consistent, reliable seal is essential to prevent weak closures, open edges, leakage, and contamination risk.
However, reliable sealing depends on more than temperature, pressure, and dwell time. Film thickness, multilayer material behavior, product residue, jaw temperature distribution, line speed, and pressure uniformity can all change how the seal forms. As a result, manufacturers may face inconsistent seal strength, package deformation, product loss, rework, or rejected batches.
Simularge’s physics-based digital twin predicts sealing behavior and package quality deviations in real time.
The digital twin estimates key internal conditions such as temperature distribution, heat penetration, pressure uniformity, sealing window stability, and seal failure risk beyond standard machine parameters or end-of-line inspection.
The digital twin can support:
Heat sealing process optimization
Real-time seal quality prediction
Temperature, pressure, and dwell time optimization
Early detection of weak seal or over-sealing risk
Line speed optimization without compromising seal quality
Reduced leakage, scrap, and rework
More stable packaging quality across FMCG production lines
Comparable studies show the following potential operational impact:
Below 5% Average Optimization Error
Model-based parameter optimization ensured that measured seal strength consistently remained within the desired target range, with an average deviation below 5%. [1]
For FMCG manufacturers, ensuring brand quality, product safety, and seal reliability requires shifting to zero defect manufacturing by preventing errors during production rather than detecting them afterward.
