This handbook for diagnosing and correcting web handling problems is written to assist anyone who works with webs, eiher directly or indirectly. Covering web handling fundamentals, process related technologies, and troubleshooting and solutions, The Plastic Film and Foil Web Handling Guide includes sufficient technical information to identify and correct defects in film or foil rolls. This independent and unbiased view of the subject — which is often addressed in commercial product literature — should enjoy wide appeal. The book condenses the author's 35 years of web handling expertise into one clear and readable resource. Recommended.

From the Preface: “A new way of analyzing web-handling problems is presented with the introduction of imaginary resistive tension member concepts. Guidelines are presented for roller alignment in machines, tensioning of webs, use of web spreading and guiding devices, use of razor slitters, shear knife slitters and edge trim removal. Guidelines are also presented for trim disposal and waste storage equipment. Management of electrostatic charges on webs is discussed. Winding technology is presented that addresses gage variation issues, core and mandrels, vibration, speed issues, web thickness issues, web strength issues, winding tension profile issues and lay-on roller issues...”

Target Audience: Plant managers and production supervisors; process, manufacturing, and quality engineers and technicians; packaging engineers; and others concerned with the handling of film and foil webs.
