Description

The Science and Technology of Flexible Packaging: Multilayer Films from Resin and Process to End Use, Second Edition provides a comprehensive guide on plastic films in flexible packaging, covering scientific principles, materials properties, processes and end use considerations. Sections discuss the science of multilayer films in a concise and impactful way, presenting the fundamental understanding required to improve product design, material selection and processes. In addition, the book includes information on why one material is favored over another and how film or coating affects material properties. Descriptions and analysis of key properties of packaging films are provided from engineering and scientific perspectives. With essential scientific insights, best practice techniques, environmental sustainability information and key principles of structure design, this book provides information aids in material selection and processing, how to shorten development times and deliver stronger products, and ways to enable engineers and scientists to deliver superior products with reduced development time and cost.
