For every material used in food contact, there must be sufficient scientific information to demonstrate that its use is safe. At room temperature, the thermoplastic polymer is a solid but when heated above 100 °C it flows. People can come into contact with styrene from the small amounts that may be present in air (primarily from automobile exhaust and cigarette smoke) and in foods and packaging. CD and DVD cases, foam packaging peanuts for shipping, food packaging, meat/poultry trays and egg cartons typically are made with polystyrene to protect against damage or spoilage. Polystyrene is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene. FDA has for decades stated that polystyrene is safe for use in contact with food.
