When it comes to distinguishing the materials of cling films, the main thing is to distinguish whether they are PE or PVC. Because there are still significant differences between the two different materials of plastic wrap. In order to prevent everyone from mixing them together, we will introduce methods for identifying their materials in the following content.

Method 1: Look at the color of the cling film roll

It is a commonly used method to distinguish the material of a cling film roll based on its color. Generally speaking, the yellowish ones are made of PVC material, while the white ones are made of PE material. I believe this explanation will make it easier for everyone to understand.

Method 2: Determine by touching the cling film

PE fresh-keeping film generally has poor viscosity and transparency, and it is easy to open when rubbed by hand, but it will break after stretching; PVC cling film has good transparency and viscosity, but it is not easy to unfold after being rubbed by hand. It can be greatly widened and elongated without breaking, making it easy to stick to the hands.

Method 3: Determine by burning

If it is PVC cling film, its flame is yellow green, and the smoke is also relatively large, and there is no oil dripping phenomenon. This is because it itself contains chlorine.
