A polyvinyl chloride wrap film composition is provided to improve general properties required for a polyvinyl chloride resin wrap film and to ensure excellent softness, elongation, windability, and transparency. A polyvinyl chloride wrap film composition comprises polyvinyl chloride 50-70 parts by weight with the degree of polymerization of 1200-1300 or 1550-1750; at least one plasticizer 20-40 parts by weight selected from diethylene glycol, triethylene glycol or their mixture, and acetylated monoglycerine; and an antifogging agent the 1-5 parts by weight which is a fatty acid ester compound. The specific gravity of the diethylene glycol or triethyleneglycol is 0.95-1.05 g/cm^2 and the specific gravity of the acetylation mono glycerine is 0.94-0.95 g/cm^2. |
