PVC cling film has good transparency and high tensile strength, so it is often used for preserving fresh fruits and vegetables. For meat, cooked food, hot food, and other foods containing fat, it is best to use PE plastic wrap.
Method for distinguishing PVC cling film from PE cling film:
1. Look at the color. The whole roll with yellowish color is made of PVC material, and the white one is made of PE.
2. Rub your hands. PE cling film generally has poor adhesion and is easy to open when rubbed by hand, while PVC cling film has better adhesion and is not easy to unfold when rubbed by hand.
3. Burn it. After being ignited with fire, PE cling film burns rapidly and will not extinguish even when away from the source of fire; PVC cling film is not easy to ignite, it will extinguish after leaving the fire source, and has a pungent odor.
