Abstract

표피재 및 45초 이하의 결정화 속도틀 갖는 폴리프로필렌 수지 조성물로 구성된 심재층으로 구성되고, 상기 표피재는 심재층에 전체적으로 접합되어 있는 다층 성형품. 상기 다층 성형품은 표피재 및 45초 이하의 결정화 속도를 갖는 용융 폴리프로필렌 수지 조성물을 한쌍의 상부 및 하부 금청 사이로 공급하고, 금형 내에서 용융 폴리프로필렌 수지 조성물을 성형함과 동시에 표피재를 성형수지 조성물의 표면에 접합시킨 다음 용융 수지 조성물을 냉각하여 고화시킴으로써 제조될수 있다. 상기 다층 성형품은 표피재의 부드러운 감촉이 손상됨이 없이 작은 변형량을 갖는다.
