Plastic film and a method for manufacturing same

The present invention relates to a plastic film and a method for manufacturing same. A plastic film, which is formed such that at least one part has a curved shape, can have high hardness, impact resistance, scratch resistance and high transparency. The plastic film is light and will not be easily damaged by external pressure and thus can substitute for the existing glass and is expected to be used for various electronic products such as a display and the like. In particular, the plastic film has at least one part in a curved shape and thereby is expected to be used for products in various shapes which cannot be manufactured by means of the existing glass. Moreover, a method for manufacturing a plastic film enables manufacturing of a plastic film having at least one part in a curved shape without curls or cracks as well as simultaneous performing of heat molding and heat curing, thereby increasing the productivity of a plastic film.
