What the materials cover

The materials from this seminar cover sealing layers and sealing films for flexible packaging. They describe typical materials and sealing layer systems, their properties, and the influence of additives and test methods. The sealing processes heat seal, impulse and ultrasonic sealing are examined, starting from material properties. Further sections address peelable seals as an alternative to permanent sealing, the basics of polymer chemistry in sealing, systematic film formulation, and requirements for a film-based package. The materials are intended for professionals in production, development, packaging technology, quality assurance, purchasing, sales and marketing who want to refresh or deepen their knowledge of sealing media.
