This book focuses on the preparation and characterisation of polyvinyl alcohol (PVA)/ halloysite nanotube (HNT) bionanocomposite films with different HNT contents for potential use in food packaging. It examines the effect of material composition and nanofiller content on mechanical, thermal and optical properties in relation to their morphological structures, and also comprehensively describes the water resistance, biodegradation and migration rates of such bionanocomposites, as well as their barrier properties in terms of water vapour transmission, and water vapour, air and oxygen permeabilities. Further, this book discusses the use of Nielsen model and Cussler model to predict the relative permeability of bionanocomposites, demonstrating that Nielsen model is more effective and in better agreement with experimental data obtained. Lastly, it discusses the application of bionanocomposite films in food packaging to prolong the shelf life of freshly cut avocados and peaches.
