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.
Claims13
A flexible plastic film comprising:
- a support substrate;
- and an ultraviolet curable coating layer formed on at least one surface of the support substrate,
- wherein the film exhibits a pencil hardness of 6 H or more under a load of 750 g, and
- when placing the film at an interval of 4 mm in the middle of the film, allowing the film to stand while both sides of the film being folded at 90 degrees toward the bottom surface at room temperature, and then spreading the film on a flat bottom surface, a height lifted from the bottom surface is 0.5 mm or less.
