Beschreibung
Zusammenfassung:	Disclosed herein is a foamable resin composition for a foam sheet including polylactic acid resin particles, each of the particles having a particle size of about 1 μm to about 100 μm. A process for preparing a particulate polylactic acid resin includes: introducing a polylactic acid resin and then forming a molten polylactic acid spray solution; and injecting the molten polylactic acid spray solution by a melt spray method and simultaneously cooling the molten polylactic acid spray solution to obtain a particulate polylactic acid. In addition, disclosed herein is a process for preparing a foam sheet using the foamable resin composition for a foam sheet including a polylactic acid resin.
