Abstract
The invention relates to production of PVC films, in particular to a PVC film and a production process thereof. The PVC film production process comprises the following steps that S1, an injection molding mechanism I conducts injection molding on a forming mechanism I to form a film middle layer; and S2, an injection molding mechanism II conducts injection molding on a forming mechanism II to form a film outer side layer. The PVC film production process further relates to a PVC film production device. The PVC film production device comprises a device support, the forming mechanism I, a transverse moving motor, a movable support, the forming mechanism II, the injection molding mechanism I, the injection molding mechanism II and a delay mechanism, wherein the injection molding mechanism I can conduct injection molding on the forming mechanism I to form the film middle layer, the film middle layer passes through the forming mechanism II through a preheating roller, the injection molding mechanism II conducts injection molding on the forming mechanism II on the basis of the film middle layer to form the film outer side layer, the film is stored through a storage mechanism, the injection molding raw materials of the film middle layer and the film outer side layer can be PVC, and the injection molding raw materials can also be other raw materials which can be used for injection molding according to use requirements.
