There are many aspects to judge the quality of cling film. Smelling is a simple and feasible way. You can smell the smell of cling film as long as you open the package. The quality of cling film is really qualified without any smell, so once the cling film has a peculiar smell, it means that its quality is not qualified; another intuitive feature is reflected in the color. The higher the transparency of the cling film, the better the quality. The yellow cling film is made of recycled waste and has poor quality.

Another way is to look at the elasticity of the cling film. The cling film is pulled and tested. The quality of cling film that is easy to break is poor. This is also a very important point. The quality of cling film is not determined by its thickness, but by its toughness. The higher the toughness, the better the quality of the cling film.

Finally, it is recommended to buy cling film in a regular shopping mall or supermarket, and pay attention to the material and production date, especially whether it is a qualified cling film from a regular manufacturer, to avoid buying and using inferior cling film.
