Patent ID: 8900698

Claim:
A polylactic acid based resin sheet comprising multiple layers wherein a core layer comprises polylactic acid resin and a layer is formed of a composition (D) containing polylactic acid (A), an ionic surface active agent (B), a nonionic surface active agent (C) and an impact strength modifier (E) comprising a multi-layered structured polymer, wherein content of the impact strength modifier (E) is 2 mass % or more and 20 mass % or less in the entire 100 mass % of the composition (D), content of the polylactic acid (A) is 50 mass % or more and 99.5% or less in the entire 100 mass % of the composition (D), mass ratio, (B)/(C), between the ionic surface active agent (B) and the nonionic surface active agent (C) satisfies 6 ≦(B)/(C) ≦18, and the resin sheet has a haze value of 10% or less and either or both of the outermost layers are formed of the composition (D).
