摘要： Provided is a method of manufacturing a molded body. The method includes: producing a foam sheet having a crystallinity degree A of 7.5% or less by using a composition containing polylactic acid comprising 98 mol % or more of any one among a D-isomer of lactic acid and an L-isomer of lactic acid as a constituent monomer unit; and molding the foam sheet with heat to produce a molded body, and a difference (B−A) between the crystallinity degree A of the foam sheet and the crystallinity degree B of the molded body is 20.0% or more and 40.0% or less.

摘要： A foam sheet includes a polylactic acid resin composition that includes a polylactic acid resin. The polylactic acid resin includes 98% mol % or greater of D-lactic acid or L-lactic acid that is a constituent monomer unit of the polylactic acid resin. An amount of the polylactic acid resin is 98% by mass or greater relative to a total amount of organic matter of the foam sheet. The foam sheet has a bulk density of 0.063 g/cm3 or greater and 0.250 g/cm3 or less. A surface roughness Sq (root mean square height of the surface) of the foam sheet defined by ISO 25178 is 7 μm or less.

摘要： A foam sheet includes a polylactic acid resin composition that includes a polylactic acid resin and inorganic particles. The polylactic acid resin includes 98 mol % or greater of D-lactic acid or L-lactic acid that is a constituent monomer unit of the polylactic acid resin. An amount of the polylactic acid resin is 98% by mass or greater relative to a total amount of organic matter of the foam sheet. The inorganic particles include grains of sheet silicate. The grains of the sheet silicate have a mean volume diameter of 10 μm or greater and 200 μm or less, and an aspect ratio of 10 or greater and 100 or less. An amount of the grains of the sheet silicate in the foam sheet is 2% by mass or less.

摘要： Provided is a foam sheet including a composition including polylactic acid. The polylactic acid includes, as monomer units, D-lactic acid and L-lactic acid, and an amount of the D-lactic acid or the L-lactic acid in the polylactic acid is 90 mol % or greater but less than 98 mol %. An amount of the polylactic acid is 97% by mass or greater relative to a total amount of organic matter in the foam sheet. When the foam sheet is cut into a square test piece, and the test piece is heated and stored for 90 minutes in a hot air circulation dryer a temperature of which is maintained at 90° C.±2° C., a change rate of an area of the test piece before and after the heat storage is within ±15%. An average thickness of the foam sheet is 0.5 mm or greater.
