Polyvinyl chloride film, also PVC film, is a film prepared by polyvinyl chloride resin and other modifiers through a preparation process. It is generally used for panel surface packaging, electrical adhesive tape, and shoes, toys, and raincoats in daily life. , tablecloths, etc., are widely used. PVC film is insoluble in water, alcohol, gasoline, and can swell or dissolve in ether, ketone, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons. At room temperature, it is resistant to concentrated hydrochloric acid, 90% sulfuric acid, and 50%-60% nitric acid. And caustic soda solution below 20%.
