Kunststoffe haben sich zu der wichtigsten Klasse von Verpackungsmaterialien entwickelt. Ihre Durchlässigkeit für Stoffe aus der Umgebung hat großen Einfluß auf die Haltbarkeit und Qualität des verpackten Guts. Gleichzeitig spielen auch die Wechselwirkungen von Bestandteilen des Verpackunsmaterials mit dem Inhalt eine entscheidende Rolle.Das vorliegende Buch ist bei der Suche der optimalen Kunststoffverpackung unverzichtbar. Es ermöglicht eine Einschätzung der Einflüsse auf das Gut aus der Umgebung und durch die Verpackung. Die Autoren beschränken sich dabei nicht auf die theoretische Beschreibung von Diffusions- und Transportphänomenen sondern übertragen die Erkenntnisse auch auf Verpackungsprobleme in der Praxis.Im Zentrum stehen Lebensmittel als Hauptanwendungsgebiet für Verpackungen aus Kunststoff. Sie können als Modellsubstanzen betrachtet werden, und die mit ihnen gemachten Erkenntnisse sind auf andere Güter zu übertragen. Es werden die maßgeblichen Vorschriften der Europäischen Gemeinschaft und der Vereinigten Staaten vorgestellt. Weitere Schwepunkte bilden die Prüfmethoden zum Nachweis des Massentransports und die sensorische Überprüfung der Produktqualität. Schließlich werden auch die anderen wichtigen Einsatzgebiete von Kunststoffverpackungen wie die Verpackung von Chemikalien oder Treibstoffen beschrieben.

About the author
Dr. Piringer is a chemist working in the field of packaging since 1978 at the Fraunhofer Institute of Food Technology and Packaging in Munich. In 1997 he co-founded the FABES research company which specializes in analysis and evaluation of mass transfer. His main activities are testing interactions between packaging and materials intended to come into contact with food and other products like drugs, cosmetics, fuel, or chemicals. In addition he develops analytical methods for determining the migration of toxicologically relevant substances and decomposition products into packed goods as well as sources of off-flavours occurring during their storage. As a leading expert in this area he serves on national and European Committees dealing in food law for food contact packaging materials. Otto-Götz Piringer is a member of the Plastics Commission of the German Federal Institute of Risk Assessment in Berlin, formerly known as the German Federal Health Office. He is author and co-author of more than 100 scientific papers.Dr. Baner, who has degrees in food science, packaging and agricultural engineering, has been researching and working in the packaging field since 1981. He has worked at Michigan State University, the Fraunhofer Institute of Food Technology and Packaging in Munich, the Nestle Research Center in Lausanne and is currently a research packaging scientist with Nestle Purina Petcare in Saint Louis. His research areas encompass the experimental determination and estimation of permeation, diffusion, sorption and migration of flavor molecules and packaging constituents between packaged goods and their packaging. Albert Lawrence Baner is author and co-author of more than 30 scientific papers.
Summary
Plastics are the most important class of packaging materials. This successful handbook, now in its second edition, covers all important aspects of plastic packaging and the interdisciplinary knowledge needed by food chemists, pharmaceutical chemists, food technologists, materials scientists, process engineers, and product developers alike.
This is an indispensable resource in the search for the optimal plastic packaging. Materials characteristics, additives and their effects, mass transport phenomena, quality assurance, and recent regulatory requirements from FDA and European Commission are covered in detail with ample data.
