Zusammenfassung:	The present invention provides a biodegradable card composition, which contains, based on 100 parts by weight of polylactic acid, 20 to 60 parts by weight of a reinforcing agent, 1 to 20 parts by weight of a crystallizing agent, 5 to 30 parts by weight of titanium dioxide, 0.1 to 5 parts by weight of a dispersant, 0.1 to 5 parts by weight of a stabilizer, 0.1 to 3 parts by weight of an antioxidant and 0.1 to 5 parts by weight of an ultraviolet stabilizer, and a method for manufacturing high-performance cards using the same. The biodegradable card composition. The biodegradable card composition according to the present invention has improved heat resistance, low temperature impact resistance, shielding ability, surface glossiness due to crystallization enhancement, strength and rigidity elasticity and durability as a card. 본 발명은 폴리락티드산 100중량부 기준으로, 보강제 20 내지 60중량부, 결정화제 1 내지 20중량부, 이산화티타늄 5 내지 30중량부, 분산제 0.1 내지 5중량부, 안정화제 0.1 내지 5중량부, 산화방지제 0.1 내지 3중량부, 및 자외선 안정화제 0.1 내지 5중량부를 포함하는 생분해성 카드 조성물 및 이를 이용한 고기능성 카드 제조방법을 제공한다. 본 발명에 따른 생분해성 카드 조성물은 향상된 내열 특성과 저온 충격성, 차폐성, 우수한 휨 특성은 물론 결정화 증진에 의한 표면 광택성 및 카드로써의 강도와 강성, 탄성력과 내구성을 갖는다.
