PROBLEM TO BE SOLVED: To provide a styrene-based resin composition having a reduced monomer content, furthermore having an extremely low content of oligomers especially trimers, which is easy to thermally decompose when molded and to form monomers, and also having an excellent processing stability, and to provided a food packaging material using it. SOLUTION: The styrene-based resin composition comprises a styrene-based polymer which is obtained by an anionic polymerization and which has a styrene trimer content of 250 ppm or less, and the food packaging material uses the composition. |
