Texture
PVC cling film is typically softer and more flexible than PE cling film, which tends to be stiffer.
01
Clinging Properties
PVC cling film adheres more strongly to surfaces due to its electrostatic charge, while PE cling film relies more on the pressure applied to the surface for adhesion.
02
Transparency
PVC cling film tends to be clearer and more transparent than PE cling film, which may have a slightly cloudy appearance.
03
Recycling Code
Check the recycling code on the packaging to identify the material. PVC cling film is typically marked with the number "3", while PE cling film is marked with the number "4".
04
Burn Test
A burn test can also help differentiate between the two materials. PVC cling film burns with a green flame and emits a chlorine-like odor, while PE cling film burns with a blue flame and smells like wax.
