PURPOSE: A biodegradation property antistatic multilayer sheet having an excellent shock resistance and a heat resistance is provided to have an antistatic function by coating an antistatic coating liquid. CONSTITUTION: A biodegradation property antistatic multilayer sheet having an excellent shock resistance and a heat resistance comprises a polylactic acid (PLA) as a main component. The multilayer sheet comprises an internal layer (A) which comprises a rubber modified graft copolymer and the PLA, and an outer layer (B) which comprises a polymethyl methacrylate (PMMA) group homopolymer, or a mixture of the PLA and polymethyl methacrylate more than one selected from a copolymer. The multilayer sheet is a biodegradation property sheet of B/A/B structure, and an antistatic coating liquid is formed in one side or both sides as a coating film with 0.01 to 1.0 g/m^2. |
