This is a complete illustrated guide and reference to today's plastic films for packaging. All significant aspects of plastic films for packaging are clearly and concisely presented: from materials, processes and machinery to applications and regulatory, social and economic considerations. More than 70 schematics illustrate materials, processes and package constructions. More than 30 tables provide important reference data in convenient form. The authors are leading authorities on plastic packaging films with first-hand experience in the R&D of many of today's widely used films. Published in cooperation with the Institute of Packaging Professionals.

Permeability properties are essential data for the selection of materials and design of products across a broad range of market sectors from food packaging to Automotive applications to Medical Devices. This unique handbook brings together a wealth of permeability data in a form that enables quick like-for-like comparisons between materials. The data is supported by a full explanation of its interpretation, and an introduction to the engineering aspects of permeability in polymers. The third edition includes expanded explanatory text which makes the book accessible to novices as well as experienced engineers, written by industry insider and author Larry McKeen (DuPont), and 20% new data and major new explanatory text sections to aid in the interpretation and application of the data. A unique collection of permeability data designed to enable quick like-for-like comparisons between different materials Third edition includes 20% new data and expanded explanatory text, which makes the book accessible to novices as well as experienced engineers Essential reference for materials engineers, design engineers and applications engineers across sectors including packaging, automotive and medical devices

Polymers are permeable, whilst ceramics, glasses and metals are gener ally impermeable. This may seem a disadvantage in that polymeric containers may allow loss or contamination of their contents and aggressive substances such as water will diffuse into polymeric struc tures such as adhesive joints or fibre-reinforced composites and cause weakening. However, in some cases permeability is an advantage, and one particular area where this is so is in the use of polymers in drug delivery systems. Also, without permeable polymers, we would not enjoy the wide range of dyed fabrics used in clothing and furnishing. The fundamental reason for the permeability of polymers is their relatively high level of molecular motion, a factor which also leads to their high levels of creep in comparison with ceramics, glasses and metals. The aim of this volume is to examine some timely applied aspects of polymer permeability. In the first chapter basic issues in the mathema tics of diffusion are introduced, and this is followed by two chapters where the fundamental aspects of diffusion in polymers are presented. The following chapters, then, each examine some area of applied science where permeability is a key issue. Each chapter is reasonably self-contained and intended to be informative without frequent outside reference. This inevitably leads to some repetition, but it is hoped that this is not excessive.
