The invention relates to a plastic film and a preparation method thereof. The plastic film formed so that at least a portion has a curved shape may have high hardness, impact resistance, scratch resistance, and high transparency. The plastic film is lightweight and not easily damaged by external pressure, so it can replace existing glass and is expected to be used in various electronic products such as displays and the like. In particular, at least one portion of the plastic film has a curved shape, and thus is expected to be used for products of various shapes that cannot be manufactured by existing glass. In addition, the method of producing a plastic film can produce a plastic film having at least one portion having a curved shape without curling or cracking, and can simultaneously perform thermoforming and thermosetting, thereby improving the productivity of the plastic film. |
