Pareto-based design of experiments for identifying and comparing optimum sealing parameters of heat sealing applications in packaging machines

Sealing is one of the most important process steps in industrial packaging, because sealed seam sensitive section a package terms quality. For this reason, major focus flexible packaging sealing process, and among this, heat frequently used technology. In detail, applications processes are confronted with four conflicting objectives: increasing quality, reducing dwell time, temperature, robustness towards varying conditions. Typical problems, such as identification optimum parameters or selection appropriate film, subject to these objectives. This paper presents recently published design experiments for characterizing comparing properties films based on multi-objective optimization algorithm. The approach provides easy-to-read charts showing all regard essential objectives sealing: robustness. Three case studies show exemplary new approach: 1) analyzing transport damages beverage powder packages; 2) identifying parameter standard, mono-material, fiber film regarding tightness visual produced sachets; 3) effect additional aluminum layers characteristics hot-tack.The may provide basis standard test method optimal processes.
