Zusammenfassung:	The present invention relates to a temporary protective film for protecting a thin film encapsulation layer in a flexible OLED display manufacturing process. According to the present invention, an OLED thin film encapsulation protection film can provided which has excellent wettability and ultra-low adhesiveness without leaving residue on an adhered object, and thus can effectively protect a thin film encapsulation layer from external contaminants in an OLED display manufacturing process and improve a degree of completion of an OLED display product. The OLED thin film encapsulation protective film includes a substrate layer and an adhesive layer, wherein the adhesive layer includes a polyurethane resin, a thermosetting crosslinking agent, and multi-arm polyethylene glycol. 본 발명은 유연 OLED 디스플레이 제조 공정에서 박막 봉지층을 보호하기 위한 임시 보호 필름에 관한 것으로, 젖음성이 우수하고 초저점착성을 가지면서 피착 대상에 잔사물을 남기지 않아 OLED 디스플레이 제조 공정에서 박막 봉지층을 외부 오염물질로부터 효과적으로 보호할 수 있고 OLED 디스플레이 제품의 완성도를 향상시킬 수 있는 OLED 박막 봉지 보호용 필름을 제공할 수 있다.
