Abstract

The present invention relates to a flexible plastic film, and more specifically to a flexible plastic film having excellent flexibility while exhibiting high hardness. According to the present invention, the flexible plastic film exhibits flexibility, bending property, high hardness, scratch resistance and high transparency, and hardly has a risk of damaging the film even in a state of being warped for a long period of time, and thereby can be usefully applied to flexible mobile devices, display devices, front face and display unit of various instrument panels, and the like.
