Food cling film can be said to be ubiquitous in people's daily lives, especially in summer, which is the peak season for the use of food cling film. Today, our professional food cling film manufacturer, Juyou Paper Plastic Products' technical editor, will explain how to distinguish the quality of food cling film on our market.
Firstly, as consumers, we have no idea what material food cling film is made of. Therefore, we rely on our eyes to determine the color of the entire roll of cling film. If it is white, it is made of PE material, and if it is slightly yellowish, it is made of PVC material.
Next, let's touch it with our hands. Generally, the viscosity of our PE cling film is not very good, nor is it very transparent. It is prone to breakage during the stretching process. Our PVC cling film is excellent in these aspects.
Thirdly, we can use a lighter to burn it. At this time, everyone must pay attention to the safety of using fire. After the PE protective film ignites, the flame is yellow and burns quickly. It will not immediately extinguish when leaving the fire source, and there may be oil dripping. However, PVC protective film is different. The flame is yellow green, the smoke is strong, and it extinguishes after leaving the fire source. It has a strong irritant odor and does not produce oil droplets.
