Summer is approaching, and I believe everyone should start using plastic wrap for food refrigeration. As a professional manufacturer engaged in the production line of PVC plastic wrap, we will help you summarize some methods for identifying the quality of plastic wrap in the following content, hoping to be of use to you.

The first method is to ignite and burn. After igniting the PE cling film with fire, the flame turns yellow and quickly burns, making it difficult to extinguish, with oil dripping and no pungent odor. Relatively speaking, PVC plastic wrap burns quickly and will not extinguish even after leaving the fire source. It also emits black smoke, with an unusually pungent odor, and black impurities after the fire is extinguished.

The second method is to look at the product description. If there is PE or polyethylene cling film on it, you can use it with confidence; If it is marked with PVC or does not indicate the material, try not to buy it. In addition, when consumers purchase plastic wrap, they should also identify the plastic wrap with the "QS" logo in order to purchase it with confidence.

In addition to the above two methods, you can also try rubbing with your hands. PE cling film is generally sticky and easy to peel off when rubbed by hand; However, PVC cling film has good adhesion and is not easy to unfold when rubbed by hand.
