Mass Transport & Reactive Barriers in Packaging: Theory, Applications, and Design Conference
Description:
• Applied theory of barrier performance and analysis
• Optimized design data for reactive barriers in packaging
• New tools for barrier performance prediction and testing
• Hundreds of worked problems and EXCEL-based calculations
This book is a systematic and comprehensive presentation of the structure and barrier properties of polymer films. Starting from a presentation of how gases and liquid solutes permeate films, the book explains the performance limits of polymer barriers under multiple conditions and with many types of permeants. Information on mass transport within films is related to film structure, and in turn is used to illustrate how engineers can predict properties and performance for single and multilayer barriers.
The technology offered here will enable packaging engineers, food scientists, and polymer specialists to design highly specific barriers using polymers—by providing the tools to carry out materials selection, multilayer design, and chemical analysis.

Editorial Reviews

Review

The authors took extra care in laying out this book. The style and quality of writing are excellent, as are the flow of the argument and the continuity from chapter to chapter...The analytical approach used in the text makes this book different from other monographs in the field. The chapter on polymer nanocomposites is timely and presents a good summary of existing literature. I strongly recommend this book to students of polymer nanocomposites and those interested in transport in packaging applications. --Professor Sadhan C. Jana, Dept. of Polymer Engineering, University of Akron

Review of the book Mass Transport & Reactive Barriers in Packaging; Theory, Applications and Design by Stanislav Solovyov and Anatoliy Goldman; DEStech Publications Inc., Lancaster, PA, USA, 2008. This is a really useful book in spite of its long and complex title ! Obviously when dealing with barriers one talks about mass transport across them, the mass transport phase is superfluous. It is not true that the book is limited to reactive barriers. Passive barriers are discussed too. A title like Barriers in Packaging would have been sufficient. As noted in the Preface, poly(ethylene terephthalate) (PET) bottles have been introduced commercially already in 1973. Advantages of plastic bottles instead of metal or glass packaging are spelled out already on the first page of the Preface: clear, transparent, lightweight, shatter resistant (compare glass). Since 1973 there has been an explosion in the use of plastic bottles we all know. The main problem in the use of plastic bottles is well known not only to educators, scientists and engineers but also to laymen: after a period of shelf time, carbon dioxide escapes and the drink becomes flat . The book under review provides solutions to this problem. Unusual is the fact that the solutions have been largely developed by the authors themselves. This in contrast to other books where we often read Brown has developed a solution X to the problem while Jones developed a solution Y . This is politically correct but the reader ends his persual of such a book in the state of bewilderment: is the Route X better or worse than the Route Y ? Barrier behavior which is defined by permeability is really a two-way street. On one hand, carbon dioxide gradually disappears from our favorite mineral water. On the other, liquid vapors and gases come inside. In spite of the large volume of soft drinks, polymeric bottles are also used as containers for a variety of other liquids such as car motor oils. For some of these liquids moisture coming from outside causes deterioration of the function of the liquid inside. Thus, the problem exists not only for water-based liquids inside the bottles. As already mentioned, Solovyov and Goldman discuss passive as well as active barriers. A passive barrier is defined as any material made into a membrane that lowers the rate of mass exchange of a solute (including a permeant) by diffusion or convection. Active barriers are chemically reactive. As the authors argue, active barriers constitute a major development in packaging. Solovyov and Goldman have tackled quite successfully a difficult problem. Systems with continuous diffusion in both directions are far from equilibrium. Development of models which can describe - and more importantly predict - phenomena that take place is a major achievement of the authors. A very important component of the book are numerical examples with solutions. The examples go directly to the heart of the problem. Thus, on p. 221 we have an example with two different values of partial oxygen pressure inside the packaging and a question: How long will it take to remove that oxygen amount in both cases ? . More than anything else, the examples show how the calculation methods developed by Solovyov and Goldman are powerful - and thus useful for industry. According to the information which the International Council on Materials Education has, there are no courses on barriers in packaging. However, courses in Polymer Science and Engineering are taught around the world. The book under review provides a basis for a module in such a course. Courses in Materials Science and Engineering could well use a segment on the subject too. One possible good start could be Chapter 11 which deals with practical methods of permeability control. --Witold Brostow, University of North Texas, Denton
