Styrene is a type of plastic that is commonly used in packaging materials, such as foam trays, cups, and containers. It is a lightweight and versatile material that is easy to mold, making it a popular choice for packaging applications. Styrene has good insulation properties, which makes it ideal for use in food packaging, as it can help to keep food hot or cold. However, there are some concerns about the safety of styrene, as it is classified as a possible human carcinogen by the International Agency for Research on Cancer (IARC). As a result, some countries have restricted or banned the use of styrene in food packaging, and alternatives are being developed.
