What the materials cover

The presentation materials for this seminar on sealant media for film packaging explain how sealing layers are built and how they perform in packaging applications. Key topics include the seal seam, the polymer chemistry basics relevant to sealing, typical sealant layer systems, and peelable seals as an alternative to permanent sealing. Additives and their influence on sealing behaviour, test methods, and the heat-contact, impulse and ultrasonic sealing processes are also covered. Further material addresses systematic film formulation, common practical problems and a hands-on exercise. The documents are aimed at professionals in production, development, packaging technology, quality assurance, purchasing, sales and marketing who want to refresh or deepen their knowledge of sealant layers.
