Heating conditions of PE, PVC and PVDC cling films
I.Polyethylene (PE Cling Film):
Polyethylene (PE): commonly considered a relatively safe choice and suitable for daily use;
It can generally be used for microwave heating, but when heated for a long time and at a temperature exceeding 110 ℃, hot melting phenomenon may occur. Therefore, it is recommended not to wrap food with this type of cling film in the microwave for a long time and use ultra-high temperature and long-term heating.
II.PVC Cling Film
Polyvinyl chloride (PVC): may contain plasticizers, it is recommended to avoid using it in food packaging;
This type of plastic wrap contains plasticizers and may release harmful substances at high temperatures. It is not recommended to use it for heating.
III.Polyvinylidene chloride (PVDC Cling Film)
Polyvinylidene chloride (PVDC): It has better barrier performance, but its cost is high and environmental impact also needs to be considered. The cling film of this type of material has good performance and can withstand high temperatures of 140 ℃ -180 ℃. It can be used for heating, but it is recommended not to put it in a high-temperature oven for heating.
