Nowadays, products produced using plastic polymers have spread to every corner of the city. Moreover, some plastic products have been used in our daily lives and are difficult to replace. As a material with stable chemical properties, strong corrosion resistance, good pressure resistance and wear resistance, plastics are currently considered a more practical type. Moreover, due to the relatively low cost of plastic and its ability to be produced in large quantities, this material is still very suitable for some commonly used products. At present, many types of polymers have also emerged, and it can be said that plastic is no longer just one or two to three types, but has formed a collection of dozens of types, collectively known as plastics. The PVC film produced is a typical product.

　　By using this type of film, more convenience can be achieved. For example, in our daily life, the cling film we need to use after meals is made of PVC material. And this transparent cling film is actually a thin film developed from PVC transparent film. After the PVC film is formed, it has a certain viscosity and transparency, which is still very valuable for use.
