A practical and detailed evaluation of polyethylene film extrusion processes for a diverse range of products. Polyethylene film is pervasive in many aspects of everyday life in applications including consumer and bulk packaging, household items, construction, horticulture, medical and hygiene products and many more. Established now for many years the technology of polyethylene film extrusion continues to develop as newer applications often demand superior performance and more established uses strive for reduced materials consumption by downgauging. Film performance is influenced by the nature of the polymer, the manufacturing process and a wide variety of additives, as well as the option of creating ever more complex multi-layered structures by coextrusion, laminating, coating and even intentional blocking. Applications may demand stretch or shrink behaviour, mechanical strength, heat sealability and high or low permeability. This book has been written for a wide readership of technologists, engineers, marketers and students engaged in the development and production of polyolefin films for all applications. The aim is to assist in optimizing product performance, evaluating the most cost effective solutions and providing useful information on the key polymers and films commercially available. Key features of screw and die designs and film treatments, blending and formulations are evaluated. Clear diagrams are provided together with copious data.

A revised version of this book is now available.The polyethylene industry has been in the midst of major restructuring and rationalization. This has lead to joint ventures and alliances to combine technologies and exploit opportunities to maximize improvements in process productivity, catalyst innovations, and enhancements in extrusion technology and converting. This comprehensive study of the polyethylene film extrusion process describes this technology in detail. In depth descriptions of the manufacturing processes for polyethylene homopolymers and copolymers, including metallocenes, are reviewed. All aspects of machine design with particular emphasis on screws and dies including coextrusion are discussed comprehensively. With computer modeling, the interactions between equipment and polymer are quantified. All aspects of equipment design and polymer features that control melt fracture, interfacial instabilities, gauge control, output and temperature, and cooling of blown and cast film processes are presented quantitatively. This methodology will highlight solutions in troubleshooting for optimum design and operation and the best available polymer and formulation choices. All polyethylene film applications in packaging, agriculture, lamination, and construction, consumer, industrial, and health care are reviewed and discussed in depth.

A practical study of the production and potential of multilayered plastic films This book is written for the industry professional engaged in the development, production or specification of multilayered films for packaging and other industrial applications. It will enable the reader to optimize product performance and evaluate the most cost effective solutions, with useful information on the key polymers and substrates used. Multilayer film structures provide properties and performance which could not be achieved by a single material, whilst also exploiting cheap and easily processed polymers. All three processes described can be used in their manufacture, and in combination they provide yet more options and benefits. One role of this book is to explain when each should be used. This is a practical process manual filled with useful advice for the processor seeking the optimum product, describing the effects of machine design, process variables and materials selection. There is sufficient theory for the student or industry newcomer who wishes to understand how the processes work. Designers and end-users will also find plenty of information on the properties and performance that can be obtained.
