Polyvinylchloride(PVC) is variously used to produce food packaging, wrap film, sealing compound of drinking bottle cap. Safety of these PVC food package is controlled by Food Code, PVC regulation. This study was carried out researches on manufacture process, physical, chemical properties and monomer(CAS No., common name, molecular structure) of PVC to help the understanding of PVC material. Also, this study helps us the understanding of regulation through researches on the foundation of PVC regulation, the purpose of test and the comment of test method. It is considered that these informations of material properties and explanations of test method are very useful to PVC producers, users and analyzers of them.
