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.

This book provides valuable information on a range of food packaging topics. It serves as a source for students, professionals and packaging engineers who need to know more about the characteristics, applications and consequences of different packaging materials in food-packaging interactions. This book is divided into 13 chapters and focuses on the agro-food, cosmetics and pharmaceutical sectors. The first four chapters cover traditional packaging materials: wood, paper and cardboard, glass and metal. The next two deal, respectively, with plastics and laminates. Biobased materials are then covered, followed by a presentation of active and smart packaging. Some chapters are also dedicated to providing information on caps and closures as well as auxiliary materials. Different food packaging methods are presented, followed by an investigation into the design and labelling of packaging. The book ends with a chapter presenting information on how the choice of packaging material is dependent on the characteristics of the food products to be packaged.

Efficiently and profitably delivering quality flexible packaging to the marketplace requires designing and manufacturing products that are both "fit-to-use" and "fit-to-make". The engineering function in a flexible packaging enterprise must attend to these dual design challenges. Flexible Packaging discusses the basic processes used to manufacture flexible packaging products, including rotogravure printing, flexographic printing, adhesive lamination, extrusion lamination/coating; and finishing/slitting. These processes are then related to the machines used to practice them, emphasising the basics of machines’ control systems , and options to minimize wasted time and materials between production jobs. Raw materials are also considered, including the three basic forms: Rollstock (paper, foil, plastic films); Resin; and Wets (inks, varnishes, primers). Guidance is provided on both material selection, and on adding value through enhancement or modification of the materials’ physical features. A ‘measures’ section covers both primary material features – such as tensile, elongation, modulus and elastic and plastic regions – and secondary quality characteristics such as seal and bond strengths, coefficient of friction, oxygen barrier and moisture vapour barrier. Helps engineers improve existing raw material selection and manufacturing processes for manufacturing functional flexible packaging materials. Covers all aspects of delivering high value packaging to the customer – from the raw materials, to the methods of processing them, the machines used to do it, and the measures required to gauge the characteristics of the product. Helps engineers to minimize waste and unproductive time in production.
