    摘要： Disclosed is a biodegradable resin composition improved in water barrier properties. Also disclosed is a molded body formed from such a resin composition. The biodegradable resin composition comprises 100 parts by mass of a biodegradable polyester resin and 0.1-15 parts by mass of a jojoba oil and/or a polar wax. The biodegradable polyester resin may contain not less than 50% by mass of a plant-based resin. Polylactic acid can be used as the plant-based resin.

    摘要： A biodegradable gas barrier vessel comprising 100 parts of mass of a biodegradable polyester resin having a polylactic acid content of not less than 50% by mass and 0.1 to 10 parts by mass of a phyllosilicate. The degree of crystallization as measured by X-ray diffractometry is not less than 15%, and the coefficient of oxygen permeation as measured under conditions of 20° C. and relative humidity 90% is not more than 50 ml·mm/m2·day·MPa. Since the biodegradable polyester resin reinforced with the phyllosilicate has excellent heat resistance, the molded product can be heat treated at an elevated temperature. Such enhanced heat treatment conditions can further enhance the degree of crystallization of the polyester resin and thus can contribute to significantly improved gas barrier properties.

    摘要翻译： 一种生物降解性气体阻隔容器，其包含100质量份的聚乳酸含量为50质量％以上的生物降解性聚酯树脂和0.1〜10质量份的页硅酸盐。 通过X射线衍射测定的结晶度为15％以上，在20℃，相对湿度90％的条件下测定的透氧系数为50毫升/毫米2·m 2·天以下 ·MPa。 由于用页硅酸盐增强的可生物降解的聚酯树脂具有优异的耐热性，所以可以在升高的温度下对成型体进行热处理。 这种增强的热处理条件可以进一步提高聚酯树脂的结晶度，因此有助于显着提高阻气性。
