Migration test series were performed under varying conditions (kinetics up to 5 days, at
40 and 60 8C) using spiked model substances (n-alkanes mixture: C10–C40) and Tenax1 as
food simulant.
The results obtained for neat paperboard showed that at 40 8C, alkanes from C18 to C26 and at 60 8C from C18 to C28 can migrate almost for 5% of the original spiking.
Migration testing of starch-coated paperboard was evaluated, considering the effect of
different ingredients and discussed together with the information gained by micro-structural
observations.
Results for coated paperboards demonstrated significant barrier properties compared to neat materials at the tested conditions.
Finally, migration test series with originally contaminated materials were carried out.
