Quick methods to control compliance of plastic materials with food packaging regulations

摘要

A general strategy is presented, aiming to provide plastics manufactures, food industries and enforcement laboratories with quick methods to check whether migration from materials for food contact will be acceptable during the time of use. The strategy involves several steps, wit increasing time demand and cost. Monitoring extraction kinetics allows both the optimi- Zation of the extraction time, and the selection of Conditions where extraction is more severe than migra- Tion. The influence of the extracting solvent is dis- Cussed.
