EXPANDABLE RESIN COMPOSITION FOR FOAMED SHEET FOAMED SHEET METHOD FOR PREPARING PARTICULATE POLYLACTC ACID AND METHOD FOR PREPARING FOAMED SHEET

摘要

There is provided a foamable resin composition for a foamed sheet comprising polylactic acid resin particles having an average particle diameter of about 1 탆 to about 100 탆. The method for producing a particulate polylactic acid resin includes the steps of: injecting a polylactic acid resin and then forming a sprayed liquid polylactic acid solution; And a step of cooling the sprayed liquid of the molten polylactic acid by spraying by the melt spraying method and cooling it to obtain a particulate polylactic acid. Further, a method for producing a foamed sheet using the foamable resin composition for foamed sheets containing the polylactic acid resin is provided.
