    • The present invention provides a card base which is degradable by microbes in natural environment. The card base is excellent in properties necessary for card bases, such as tensile strength, impact strength, flex temperature, heat resistance, resistance to thermal expansion and contraction, blocking resistance and humidity resistance, and has rigidity, bending resistance and durability. The card base contains, as essential components, a 3-hydroxybutylate/3-hydroxyvalerate copolymer and a lactic acid polymer, and, where necessary, a polycaprolactone or a high-molecular aliphatic polyester. The card base has a single-layer structure, or a sandwich structure further having overlay layers comprising a composition containing, as essential components, a lactic acid polymer and either or both of a polycaprolactone and a high-molecular alphatic polyester.
    • 本发明提供了一种在天然环境中可被微生物降解的卡片基底。 卡片基体具有拉伸强度,冲击强度,弯曲温度,耐热性,耐热膨胀和收缩性,耐粘连性和耐湿性等卡基所需性能优异,并且具有刚性,耐弯曲性和耐久性。 卡片基本含有3-羟基丁酸酯/ 3-羟基戊酸酯共聚物和乳酸聚合物,必要时含有聚己酸内酯或高分子脂肪族聚酯。 卡片基底具有单层结构,或者具有覆盖层的夹层结构,该覆盖层包括含有作为必要成分的乳酸聚合物和聚己内酯和高分子脂肪聚酯中的任一种或两者的组合物。
