What the materials cover

The presentation materials from this seminar cover sealant layers and sealing films for flexible packaging. Starting from packaging applications, they explain common sealant layer systems and their properties, along with additives and test methods for explaining sealing effects in practice. Further topics include polymer chemistry relevant to sealing, heat sealing, impulse sealing and ultrasonic sealing, and peelable seals as an alternative to permanent sealing. Film formulation and the definition of packaging requirements are also addressed. The material suits professionals from production, development, packaging technology, quality assurance, purchasing, sales and marketing who want to refresh or deepen their knowledge of sealant layers.
