The present invention relates to the technical field of thin films, particularly to a thin film product molding method and a corresponding thin film product thereof. The thin film product molding method comprises: placing a thermoplastic thin film into a hot pressing mold with a variable mold temperature; closing the mold, heating, and carrying out hot pressing molding by using the temperature change of the mold; and opening the mold after cooling the mold, and taking out the thin film product. According to the present invention, the thermoplastic thin film is subjected to rapid heating and cooling in the hot pressing mold with the variable mold temperature, such that the high-quality product can be rapidly and efficiently obtained, and the thermoplastic thin film is uniformly heated and molded.
