How to distinguish the transparency of PVC cling film

The transparency, stretchability, and viscosity of PVC cling film are stronger than those of PE cling film. PVC cling film burns on fire, causing the flame to turn black, emit black smoke, have a pungent odor, and will not drip oil. It will automatically extinguish after leaving the fire source. When PE cling film burns, the flame is yellow, odorless, and will drip oil. It can continue to burn after leaving the ignition source. If the label is PVC material or the label is unknown, it is recommended that consumers do not purchase or use it.
