Kanai T., Campbell G.A. (Eds.) Film Processing

Hanser Gardner Publications, 1999, 446 pages, ISBN: 1569902526Discusses developments in processing hardware and operating techniques permitting increasingly high production rates, optimum property development, unusual degrees of molecular orientation and the coextrusion of multi-layer, multi-component film and sheet.
As this volume is being developed, the polymeric film industry is in a major transition from relying only on commodity resins as their film base, to the use of more well-defined materials and processes. In terms of resins, metallocene catalyzed polymers have been developed and polymer structure can now be tailored to improve or help optimize film process design. Engineering plastics such as polyethylene terephathalate (PET), polycarbonate, and polyamides have become popular resins to provide high temperature resistance in films when desired. The line speeds of film production have reached 400m/min for oriented Polypropylene and oriented PET. In addition, the technology to tenter crystal polystyrene has also been commercially developed. These achievements in high speed production and alternative starting materials follow the development of new machines, improvements in polymer material characteristics and optimization of processing techniques. A further demand for more complex, multilayered films for various uses in packaging has led to the development of more complicated die designs and control so that the required film thickness and composition can be maintained.
This book was conceived to address what appeared to be a void in the polymer processing literature. While we were pursuing our own efforts to understand the fundamentals and practical needs of the film practitioners, we found no condensed collection of the science and technology for production and evaluation of polymeric films. We have endeavored to provide the polymeric film processing community with a volume which will be a starting point regarding both the state of theory and technology of film production at the time the volume was written by the contributing authors.Film Processing: Overview and Introductory Rheology
