”Film Processing ”（フィルム成形）出版のお知らせ
プラスチック材料の２０％以上はフィルムとして使用されているにもかかわらず、研究者、技術者の専門書としてまとまった本のないことが気になっていた折、約５年前に、 Polymer Processing Society（国際高分子加工学会）より、世界の大学、大学院生および企業の研究者向けのフィルム成形に関する専門書をまとめてみないかという依頼がありました。 そこで、世界各国のフィルム関係の研究で著名な方１６名（TOSHITAKAを含めて）に原稿をお願いし、このほど、ドイツのHanser出版社から、全４２９頁の本が完成し発行になりました。
著者が世界中に散らばっており、原稿に関する問い合わせが上手く取れなかったり、また、海外の出版社との度重なる修正を加えながらの作業は予想以上に困難を極め５年の歳月が過ぎてしまいました。
こうして発行された本を実際に手にすると、これまでのことが走馬灯のように思い浮び、感激ひとしおでありました。
この本は、皆さんが毎日、目にする包装用のフィルムの成形技術に関する本です。例えば スーパーマーケットでもらう袋のフィルムやゴミ袋などのインフレーション成形から、パン包装、野菜包装、最近ではレトルト食品用フィルム、建材用化粧シートなどのキャストフィルム・押出ラミ成形、さらにお菓子や食品・繊維などの包装用のフィルム、食品用トレイ、おむすび用フィルム、ＶＨＳやオーディオ用テープ、コンデンサー用フィルムなどのニ軸延伸フィルム成形など、プラスチックフィルムに関わる成形技術、フィルムの物性、品質、成形性についてフィルム成形時の状態を理論的および実験的な両面から捉えながら現象を解明し、より品質の良いフィルムを作っていくために必要な基礎技術に重点を置いた内容の専門書です。その内容は著者と目次を見ていただくとわかると思います。
本のコンセプトを以下のPreface（序文）に 載せておきますが、この本についての紹介が、アメリカ＆ドイツに本拠地を置くHanser 社のホームページにもありますのでご参照ください。 http://www.hansergardner.com/

Volume Editor
Toshitaka Kanai
As this volume is being developed, the polymer 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 terephalate (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 extrusion is one of the most popular commercial polymer processing techniques and the resulting film products are widely used in our daily life. Recently, because of competition from other materials, the economics of film production have moved to higher productivity of film production methods; high speed lines and high quality reproducible film have been required in order to reduce the cost and to obtain the additional value. A few examples of this economically driven technology are in the production, for example very thin condenser film, very thin and dimensionally stable video recording film and multi-layered film for the protection of fresh food . To achieve these requirements, we need to have a wide base of technology, not only the traditional empirical knowledge that dominates the film industry, but also a more basic understanding of chemistry, physics and engineering that influence the film's properties. Topics introduced to the reader in this book are the structure of the polymer, the rheology of polymer, the theoretical analysis of film process, the structure and morphology of film product and the physical properties of film.
Unfortunately it is not possible to present, in a book, all of the science and technology that relates to film extrusion. This book addresses the following topics: extrusion die design and analysis, theory and technology of the blown film process, casting film process, multi-layered film technology, and biaxially oriented film analysis of both the tentering process and double bubble tubular film process. We first present a short survey of the film extrusion process and industry. Then we provide the reader with a very brief introduction the rheology, involved with film extrusion process analysis. There follows a short introduction to flat and annular die design. A substantial fraction of the book describes the biaxially orientation film process in more detail than is usually found in other collected works on this subject. Topics that are discussed in some detail are the theoretical analysis of film extrusion outside of the die, the structure of film, the physical properties of film and the relationship between these topics. Film production covers a very wide range of technology.
We appreciate the substantial efforts of all of the authors who shares new and recently developed technology in their specialized technical fields in their chapter contributions. The international of Polymer Processing Society continues to publish a series of books on polymer processing. We wish to thank Professor Warren Baker, series editor, for all of his efforts during the development of this volume. We hope our contribution to this series will help the reader develop an introductory understanding of film extrusion. A more in depth understanding can be developed by using the reference in each chapter to lead to the original literature which of course has more than can be condensed into a single.
