Abstract: Under the given conditions, the numerical simulation of the hazardous substance (BADGE·2H2O) migrated from inside wall of food cans coatings into food simulation liquid was analyzed, and the experimental results was compared with under the corresponding conditions.The result showed that migration was caused more by temperature, initial concentration and coating thickness.For a given temperature, the higher the temperature, the time when BADGE·2H2O achieved the migration balance was shorter, the amount of migration was larger.For the given initial concentration and coating thickness, with the thicker coating, the higher the initial concentration, the amount of migration was larger.At the same time, the biggest concentration difference between numerical solution and the experimental data which BADGE·2H2O migrated from inside wall of food cans coatings to water simulation liquid at different temperature was around 0.023μg/mL.There was a good fitting relationship between numerical simulation and experimental result.
