Abstract
Currently, a starting up process of development of testing and evaluation procedures for recycled polymers for food packaging use can be recognized. The inherent novelty caracter of this situation explains the uncertainty and reserve of the food and packaging industry towards packaging developments on the basis of recycled polymers. In Europe, the national regulatory point of views are differing completely, ranging from banning recycled polymers to setting them principally equal to virgin material concerning the food legislative requirements to be fulfilled. The German BgVV which introduced the latter opinion first in Europe has generated with this a solid fundament for corresponding packaging development and testing activities. At this time, generally agreed for standardized test procedures are far from being available. In the moment, individual test procedures to be established case-by-case have to be applied. In the last few years, the FhILV has undertaken considerable research effo rts to elaborate the needed test and evaluation procedures, also with the aim to propose them for future European standards. This work describes the principles of such test procedures and illustrates them by presenting practical examples and results obtained from industry supported R&D activities.
