Abstract:
1. A method for producing a resin composition, comprising the steps of: melt-kneading a raw material A comprising a polylactic acid resin, a crystal nucleating agent, and a plasticizer comprising an ester compound formed between a polycarboxylic acid having a hydrocarbon group having 1 to 7 carbon atoms and a mono-alcohol having a hydrocarbon group having 1 to 7 carbon atoms, to prepare a polylactic acid-containing melt-kneaded mixture having a relative crystallinity of 70% or more (step A); and further melt-kneading the polylactic acid-containing melt-kneaded mixture obtained by the step A and a ray material B comprising a polypropylene resin and a compatibilizing agent (step B).
