Abstract : 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).
