The present invention relates to a plastic film and a preparation method thereof. The plastic film in the present invention is formed to have a curved shape at least in part, and can exhibit high hardness, impact resistance, abrasion resistance, and high transparency. Also, the plastic film is light-weight without having risks of damage caused by an external pressure, and thus can be used to various electronic devices such as display device, or the like, in place of a conventional glass. Particularly, the plastic film can provide products in various shapes which could not be provided with a conventional glass by having a curved shape at least in part. Further, the preparation method of the plastic film in the present invention can prepare a plastic film which is at least partially curved without generating curls or cracks, and can perform thermal forming and heat curing at the same time, thereby increasing productivity of the plastic film.
