Paper Water Interactions

Moisture sorption and swelling Water sorption and paper structure Influence of temperature and water on mechanical properties Interactions of fibres and water – product demands Influence of moisture on mechanosorptive creep

Packaging materials – CANCELLED

Packaging will be presented and discussed from the performance perspective, in certain applications with a focus on food stuffs, including product safety (especially materials and barriers perspective), economics/services (systems perspective), communications and marketing, logistics, design and sustainability. Materials used in packaging, and some of the converting processes, will be covered, such as glass, metals, polymers …
