摘要: A foamed sheet of a base resin containing 50 to 100% by weight polylactic acid and having an apparent density 63 630 kg/m 3 , thickness 0.5 7 mm endothermic exothermic calorific values ΔH endo:2 exo:2 respectively, as measured heat flux differential scanning calorimetry at heating rate 2° C./min. The value is least 10 J/g the difference (ΔH −ΔH ) between less than 40 J/g. foam molding such receptacle prepared thermoforming sheet.
