What the materials cover

The documents explain how to size the barrier properties of packaging films for food appropriately. The central question is when high-barrier packaging materials are necessary and when a defined permeability is sufficient, while keeping product quality, cost and sustainability in view. Topics include requirements for food packaging materials, the barrier properties of available packaging materials, manufacturing techniques for barrier films and the basics of food spoilage. Organic and inorganic barriers, active and passive barrier systems as well as packaging tests are discussed. Two exercises assign multilayer structures to specific applications. The material is aimed at professionals in production, development, packaging technology, quality assurance, purchasing and sales.
