본 발명은 터치 스크린을 구비한 모바일 전자 장치용 스크린 보호기(5)로서, 스크린 보호기는 TPU(thermoplastic urethane) 층(3)의 일면과 결합되는 PET(polyethylene terephthalate) 층(2); 및 TPU 층의 타면에 있는 접착제 층(4)을 구비하는 평면 적층 필름을 포함한다. PET 층의 두께는 50㎛ 미만이고, 접착제 층은 5g/㎠ 보다 큰 점착력을 제공한다. 상대적으로 큰 점착력을 가지며 상대적으로 얇은 PET 층은 곡선형 스크린을 구비한 장치에 특히 적합한 스크린 보호기를 제공한다. A screen protector (5) for a mobile electronic device with a touch screen. The screen protector comprises a flat laminated film comprising a layer (2) of polyethylene terephthalate (PET) bonded to one face of a layer (3) of thermoplastic urethane (TPU) and a layer (4) of adhesive on the opposite side of the TPU layer. The PET layer is less than 50µm thick and wherein the adhesive layer provides a tack force of greater than 5 g/cm 2 . The relatively thin layer of PET with the relatively high tack force adhesive provides a screen protector particularly suited to a device with a curved screen.
