What the materials cover

These presentation materials accompany a seminar on sealing layers and sealant films for flexible packaging. They cover typical sealant layer systems and their properties, the basics of polymer chemistry as they relate to sealing, and the structure and formation of the seal seam. One focus is peelable sealing as an alternative to permanent sealing. The materials also address additives, test methods, and the heat-seal, impulse-sealing and ultrasonic sealing processes. Further topics include systematic film formulation and defining requirements for film packaging. They are intended for professionals from production, development, packaging technology, quality assurance, purchasing, sales and marketing who want to refresh or deepen their knowledge.
