The invention provides a PVC release film. The PVC release film comprises a thin film layer which comprises the following raw materials by weight: PVC, TPX, PP, 2-ethyl methacrylate, nano-barium sulfate, polyether imide, phenolic resin, polyarylester, carbon fiber, organic montmorillonite, ethylene glycol, a silane coupling agent, an antioxidant, a light stabilizer, a defoamer and a thickener. The PVC release film has a smooth and clean surface and good peel strength and tensile strength; secondly, the PVC release film has good heat stability and heat shrinkage rate, is capable of resisting light aging and can be repeatedly used; and the PVC release film has relatively balanced comprehensive performance and extremely good water resistance, solvent resistance, chemical resistance, corrosion resistance, temperature resistance, weather resistance and adhesiveness. Besides, the PVC release film provided by the invention is environmentally friendly and nontoxic, a synthetic method is simple, the operation is simple and convenient, conditions are mild, and the synthetic method is applicable to industrial production.
