Food‑Grade Modified PS Plastic

For food‑grade PS resin pellets, there shall be no peculiar odor or foreign impurities. Heavy‑metal contents such as lead, cadmium and mercury must be kept at extremely low levels to prevent health risks to consumers caused by substance migration into food. National standards impose strict limits on toxic residual monomers. For example, residual styrene monomer in food‑grade polystyrene resin shall be ≤0.15 % (1500 mg/kg). The US FDA (21 CFR 177.1640) also specifies corresponding upper limits for total residual styrene monomer based on different food‑contact scenarios.
