Different types of polystyrene used in packaging were tested for styrene monomer migration into corn oil. Several blends of general‐purpose polystyrene with different amounts of high‐impact polystyrene demonstrated a linear increase of migration of styrene with increasing amount of high‐impact polystyrene in the polymer. Faster migration was found for higher exposure temperatures. Migration depended linearly on the content of residual styrene monomer in the polymer.
