Study Of Methods To Reduce Contamination Of Food ‎from Food ‎packaging Based On Plasticized Pvc ‎(argon Plasma)‎

In this work we studied a surface treatment process using argon ‎plasma to reduce the migration of the additives contained in the ‎initial plastic package (PVC) stabilized with sunflower oil ‎epoxidized and to identify the migrant substances.‎ One formulation was considered (in the presence of 40 % of ‎plasticizer), migration tests are done under 40°C with agitation in ‎crude olive oil.‎ The migration phenomenon is studied on the bases of a ‎preliminary analysis on the variation of the weight of test tubes of ‎PVC with the help of three technical analyses: Fourier transform ‎infrared (FTIR) and scanning electron microscopy (SEM).‎
