The invention relates to polylactic acid foam comprising a resin composition that comprises polylactic acid (A), polyolefin resin (B) and a polyolefin resin copolymer (C) wherein the weight ratio of the polylactic acid to the sum of the polyolefin resin and polyolefin resin copolymer in the resin composition, (A)/{(B)+(C)}, is in the range of 0.2 - 6. n The polylactic acid foam used is low in the load in global environment and high in heat resistance, moldability and compression strain recovery, and this polylactic acid foam can be applied to a wide variety of uses where polyolefin resin foam has been used conventionally, including interior members of vehicles, heat insulator, cushioning medium, packing material, base of pressure sensitive adhesive tapes, and joint filler for tiles. |
