This extensively revised and updated second edition of the only data handbook available on the properties of commercial polymeric films details the permeability characteristics of over 125 major plastic and elastomer packaging materials. New to this edition are 92 resin chapters containing textual summary information including: category, general description, processing methods, applications, and general permeability considerations for water vapor, oxygen, and other gases including aroma and flavor. The product data is presented in graphical and tabular format, retaining the familiar format of the first edition and allowing easy comparison between materials and test conditions.

Annotation Assembled here from a multitude of company sources is data presented in textual, graphical, and tabular form, on the permeability and barrier properties of 125-plus thermoplastic and rubber materials, organized by family. An introductory chapter provides a primer on the nature of polymeric materials; comparative properties; processing, markets, and applications; automotive fuels; multilayer films; food and beverage packaging; standard measurements and tests; and ASTM references. Chapters for each family of material discuss processing methods, applications, and general permeability considerations for water vapor, oxygen and other gases including aroma and flavor. Product data has been normalized to SI units, allowing comparison between materials and test conditions. Appendices rate the permeability of gloves and supply information on permeation rates and permeability units conversion, and a glossary. Indexing is by trade name.

The field of engineering is becoming increasingly interdisciplinary, and there is an ever-growing need for engineers to investigate engineering and scientific resources outside their own area of expertise. However, studies have shown that quality information-finding skills often tend to be lacking in the engineering profession. Using the Engineering Literature is a guide to the wide range of resources in all fields of engineering. The information age has greatly impacted the way engineers find information. While print is still important, resources are increasingly being made available in electronic formats, and the Web is now a major resource. Engineers have an effect, whether direct or not, on almost all aspects of our lives, and it is vital that they find the right information at the right time to create better products and processes. The book takes an engineering sub-discipline approach, detailing those resources that are most important for the practicing engineer and the librarians who work in engineering. Each chapter provides a short history and description of the discipline, then lists the most important resources by format: handbooks, dictionaries, texts, journals, websites, etc. Most references include a short annotation. The authors of each chapter are well-known, experienced librarians or faculty in the appropriate engineering discipline, sharing their expertise and experiences with engineering information. This is a guide to resources that are often unknown to the practicing engineer. It also serves as a textbook for the library school student or new engineering librarian, as well as a time-saving handbook for current librarians. The arrangement of materials provides easy and logical access to evaluated resources in engineering and supporting disciplines, providing a tool that is useful in reference services and collection development.

Biaxial (having two axes) stretching of film is used for a range of applications and is the primary manufacturing process by which products are produced for the food packaging industry. Biaxial stretching of film: principles and applications provides an overview of the manufacturing processes and range of applications for biaxially stretched films. Part one reviews the fundamental principles of biaxial stretching. After an introductory chapter which defines terms, chapters discuss equipment design and requirements, laboratory evaluations, biaxial film structures and typical industrial processes for the biaxial orientation of films. Additional topics include post production processing of biaxially stretched films, the stress-strain behaviour of poly(ethylene terephthalate) and academic investigations of biaxially stretched films. Part two investigates the applications of biaxial films including fresh cut produce, snack packaging and product labelling. A final chapter investigates potential future trends for biaxially oriented films and orienting lines. Biaxial stretching of film: principles and applications is a valuable reference tool for a broad spectrum of readers, ranging from polymer and fibre engineers to electrical engineers. It will also be suitable for professionals in the food packaging and paper industries. A valuable reference tool for polymer and fibre engineers, electrical engineers and professionals in the food packaging and paper industries Provides a comprehensive overview of the manufacturing processes of biaxially stretched films and includes a discussion of their future applications Places emphasis on the technology as well as the different types of polymers used

Food Processing Technology: Principles and Practice, Fourth Edition, has been updated and extended to include the many developments that have taken place since the third edition was published. The new edition includes an overview of the component subjects in food science and technology, processing stages, important aspects of food industry management not otherwise considered (e.g. financial management, marketing, food laws and food industry regulation), value chains, the global food industry, and over-arching considerations (e.g. environmental issues and sustainability). In addition, there are new chapters on industrial cooking, heat removal, storage, and distribution, along with updates on all the remaining chapters. This updated edition consolidates the position of this foundational book as the best single-volume introduction to food manufacturing technologies available, remaining as the most adopted standard text for many food science and technology courses. Updated edition completely revised with new developments on all the processing stages and aspects of food industry management not otherwise considered (e.g. financial management, marketing, food laws, and food industry regulation), and more Introduces a range of processing techniques that are used in food manufacturing Explains the key principles of each process, including the equipment used and the effects of processing on micro-organisms that contaminate foods Describes post-processing operations, including packaging and distribution logistics Includes extra textbook elements, such as videos and calculations slides, in addition to summaries of key points in each chapter
