A comprehensive and highly practical survey of the materials, hardware, processes and applications of flexible plastic films.

Aimed at a wide audience of engineers, technicians, managers, purchasing agents and users, Multilayer Flexible Packaging provides a thorough introduction to the manufacturing and applications of flexible plastic films, covering:



Materials
Hardware and Processes
Multilayer film designs and applications

The materials coverage includes detailed sections on polyethylene, polypropylene and additives. The dies used to produce multilayer films are explored in the hardware section, and the process engineering of film manufacture explained, with a particular focus on meeting specifications and targets. The section includes unique coverage of the problematic area of bending technology, providing a unique explanation of the issues involved in the blending of viscoelastic non-Newtonian polymeric materials.

Extrusion

by Harold F Giles, JR. and John R. Wagner, Jr.

Published 1 January 2004
The second edition of Extrusion is designed to aid operators, engineers, and managers in extrusion processing in quickly answering practical day-to-day questions. The first part of the book provides the fundamental principles, for operators and engineers, of polymeric materials extrusion processing in single and twin screw extruders. The next section covers advanced topics including troubleshooting, auxiliary equipment, and coextrusion for operators, engineers, and managers. The final part provides applications case studies in key areas for engineers such as compounding, blown film, extrusion blow molding, coating, foam, and reprocessing.

This practical guide to extrusion brings together both equipment and materials processing aspects. It covers basic and advanced topics, for reference and training, in thermoplastics processing in the extruder. Detailed reference data are provided on such important operating conditions as temperatures, start-up procedures, shear rates, pressure drops, and safety.
