摘要： A foam sheet includes a polylactic acid resin composition that includes a polylactic acid resin and an epoxy group-containing compound including two or more epoxy groups per molecule. The polylactic acid resin has a weight average molecular weight of 180,000 or greater and 320,000 or less. The polylactic acid resin has a terminal hydroxyl group content of 0.3 or greater and 1.4 or less. 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 epoxy group-containing compound has an epoxy equivalent of 170 or greater and 350 or less. The foam sheet has cold crystallization enthalpy of 20 J/g or greater and recrystallization enthalpy of 20 J/g or greater.

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： An aliphatic polyester resin composition contains an aliphatic polyester resin and a cross-linking agent, wherein the proportion of the gel proportion of the aliphatic polyester resin composition is less than 5 percent, wherein the weight average molecular weight of the aliphatic polyester resin composition after the aliphatic polyester resin composition is melted at 200° C. for 10 minutes increases by 50,000 or greater compared to the weight average molecular weight of the aliphatic polyester resin composition before the aliphatic polyester resin composition is melted at 200° C. for 10 minutes.
