Written to assist anyone who works with webs directly or indirectly, The Plastic Film and Foil Web Handling Guide is a handbook for diagnosing and correcting problems with web handling technology. Covering web handling fundamentals, process-related technologies, troubleshooting, and solutions, it includes sufficient technical information to identify and correct defects in rolls (of film or foil). Readers will appreciate this unbiased look at web handling that also serves as a counterpoint to information from equipment suppliers. The text presents guidelines on: Roller alignment in machines Tensioning of webs Use of web spreading and guiding devices Use of razor slitters Shear knife slitters Edge trim removal Trim disposal Management of electrostatic charges on webs Waste storage equipment Winding technology is presented that addresses gage variation issues, cores and mandrels, vibration, speed issues, web thickness issues, web strength issues, coated web issues, laminated web issues, clear film issues, winding tension profile issues, and lay-on roller issues. A guide for troubleshooting web-handling problems and a glossary of terms for quick reference is also provided.

Written by one of the world's leading web handling expert and experienced machine designer along with a team of specialists, this hands-on book offers a step-by-step approach to investing in, acquiring and starting up web machinery. It is designed to assist plant-based personnel in the costing and planning of major machinery investment with a rigorous analysis of what needs to be done to acquire or replace equipment with minimal expense and maximum long-term efficiency, no matter what types of webs are being handled. The book ranges over the entire spectrum of machine buying from dealing with salespeople to the technical details of machinery design, contract formulation, financing and maintenance. Numerous case studies illustrate strategies to follow—and avoid—in purchasing standard, as well as custom designed, web machines. -------------------------------------------------------------------------------- From the FOREWORD (by Craig Sheppard, Executive Director, AIMCAL) "The book offers excellent and practical advice on how to: · Define equipment needs and goals · Research the options · Prepare specifications and requests for quotes · Negotiate contracts · Make decisions based on facts · Examine options such as standard, custom and one-off designs or rebuilds The guide…explains what must be done for acceptance trials, startup and documentation. Other sections of the book examine expectations for the machine's first year and explore ways to address problems…"

Vacuum Deposition onto Webs: Films and Foils, Third Edition, provides the latest information on vacuum deposition, the technology that applies an even coating to a flexible material that can be held on a roll, thereby offering a much faster and cheaper method of bulk coating than deposition onto single pieces or non-flexible surfaces such as glass. This technology has been used in industrial-scale applications for some time, including a wide range of metalized packaging. Its potential as a high-speed, scalable process has seen an increasing range of new products emerging that employ this cost-effective technology, including solar energy products that are moving from rigid panels onto cheaper and more versatile flexible substrates, flexible electronic circuit ‘boards’, and flexible displays. In this third edition, all chapters are thoroughly revised with a significant amount of new information added, including newly developed barrier measurement techniques, improved in-vacuum monitoring technologies, and the latest developments in Atomic Layer Deposition (ALD). Provides the know-how to maximize productivity of vacuum coating systems Thoroughly revised with a significant amount of new information added, including newly developed barrier measurement techniques, improved in-vacuum monitoring technologies, and the latest on Atomic Layer Deposition (ALD) Presents the latest information on vacuum deposition, the technology that applies an even coating to a flexible material that can be held on a roll, thereby offering a much faster and cheaper method of bulk coating Enables engineers to specify systems more effectively and enhances dialogue between non-specialists and suppliers/engineers Empowers those in rapidly expanding fields such as solar energy, display panels, and flexible electronics to unlock the potential of vacuum coating to transform their processes and products

From hardware and materials through processing and properties, a broad coverage of blown film extrusion is presented. A primary objective of this book is to ensure a useful balance of theory and practice. The reader will find the answers to why they encounter certain effects in the blown film process so that they are better able to troubleshoot and improve their operations. At the same time, current practices and equipment are emphasized to keep readers up-to-date with the most productive and efficient technology. The companion computer-based learning tool, The Blown Film Extrusion Simulator, is provided to enhance the reader’s understanding. This software was developed specifically to teach blown film extrusion equipment operation and processing principles, and is available for download. Throughout this book, exercises using the simulator are described to complement the methods and principles explained. New in this third edition is a chapter on polymer rheology, with an overview of the rheology of polymer melts and its effect on extruding blown film. Additionally, improvements and corrections have been made throughout the book. Contents: ? Materials for Blown Film ? Polymer Rheology ? Extrusion Overview ? Hardware for Blown Film ? Processing ? Coextrusion ? Film Properties ? Troubleshooting
