Numerical Simulation on Migration of Chemical Substances from HDPE into Foods
Numerical simulation of migration of chemical substances from HDPE into foods(simulants)isperformed based on the finite element method(FEM). The results show that concentration of migrants infoods at equilibrium increases with the increase of its initial concentration in packaging. Diffusivity of migrantsis key to migration dynamics. Partition coefficient represents ration of concentration in HDPE to that infoods at equilibrium. For multilayer packaging, functional barrier layer is able to efficiently delay migration.Thickness of barrier layers prominently influences barrier effect. The method can be utilized to predict migrationof chemical substances having mixed boundary conditions, developed as a total solution food package formigration problems.
