The color of PVC cling film is mainly slightly yellow and semi transparent, with a certain luster. PVC (polyvinyl chloride) is a polymer material whose color and transparency are influenced by various factors, 

including additives and the use of additives during the production process. Although the transparency of PVC cling film is better than that of polyethylene (PE) and polypropylene, it is inferior to polystyrene. 

PVC materials can be divided into soft and hard types, with hard products having a hardness higher than low-density polyethylene but lower than polypropylene. At the bending point, hard PVC may experience 

whitening phenomenon. ‌

In addition, PVC cling film usually has a certain yellow tone, which is determined by the characteristics of its raw materials. Most of the PVC cling films sold in the market have this slightly yellow semi transparent 

shape, which is a typical appearance feature.

This color characteristic helps consumers distinguish PVC cling film from other types of cling film, such as PE cling film, by observing the color when purchasing. The latter usually appears as white cling film, while 

the latter usually appears as white.
