Optimization of a Process Capable of Decreasing the Pollution from PVC Packaging Material

摘要

This work is the study of a process capable of decreasing the migration of the plasticizer into a liquid food or a simulant from a plasticized PVC packaging.The treatment is a two-step process: (1) soaking in a liquid,and (2) drying at various temperatures.The effciency of this method depends on many factors:nature of the liquid and immersion time,temperature and time of drying,etc.The influence of the most important of them had been quantified with a mathematical model previously described.The purpose of this study is to search for the best value of each parameterand,therefore,to optimize the reduction of mass transfers.
