PROBLEM TO BE SOLVED: To provide a polylactic acid-based resin composition which gives a bead expanded molding having a good heat resistance and favorably used for various applications and is excellent in crystallinity, and polylactic acid-based impregnated resin particles, and expanded particles composed of the resin composition.SOLUTION: The polylactic acid-based resin composition for bead expansion includes a polylactic acid resin the content of the D-isomer of which is ≤1.0 mol% or ≥99.0 mol% as the main ingredient, and a 0.1-15 mass% of a non-polar wax containing 50-90 mass% of a normal alkane. |
