The present invention relates to a novel and non-toxic plasticized polyvinyl chloride material, which comprises A) 100 parts by weight of a PVC resin, B) 20-80 parts by weight of one or a plurality of main plasticizers selected from cyclohexane-1,2-diformate diisooctyl, cyclohexane-1,2-diformate diisononyl, tributyl citrate and acetyl tributyl citrate, and C) 5-20 parts by weight of an ethylene-vinyl acetate-carbonyl copolymer adopted as an auxiliary plasticizer. The material has characteristics of no toxicity, environmental protection, no plasticizer emigration phenomenon, good transparency, suitable processing temperature and excellent comprehensive mechanical property, and can be widely used in the field of food packaging, medical devices and the like. The present invention further relates to a preparation method of the plasticized polyvinyl chloride material, and an application of the plasticized polyvinyl chloride material in food packaging and medical devices.
