What the materials cover

These presentation materials accompany the seminar on sealing media for film packaging. The focus is on typical seal layer systems and their properties, supplemented by additives and test methods that help explain effects and practical cases. Polymer chemistry basics relevant to sealing are covered, along with heat sealing, impulse sealing and ultrasonic sealing. Peelable seals form a further topic, alongside a formulation exercise and common practical problems. It addresses professionals in production, development, quality assurance, purchasing, sales and marketing who want to refresh or deepen their knowledge of seal layers.
