           Material of Food Cling Film

The food cling film is made of PE, PVC and PVDC. Which is safer?

The food cling film include PE, PVC and PVDC. In the market, the majority of food cling film are made of ethylene. According to the different types of ethylene masterbatch.

There are three types of plastic wrap:

The first is polyethylene (PE for short), which is mainly used for food packaging. We usually buy food cling film for fruits and vegetables, including semi-finished products purchased in supermarkets;

It is characterized by a wide range of use and can be used to package fatty food. It can be heated in a microwave oven, but the temperature does not exceed 110 ℃.

The second is polyvinyl chloride (PVC for short), which can also be used for food packaging, but it has a certain impact on human safety; Because PVC materials must be added with some plasticizers during processing to increase the toughness of the film, many countries have restricted their use in food packaging materials. However, PVC plastic wrap cannot be used to package oil food and cannot be used at high temperature. So everyone should pay attention (click on the blackboard and draw the key points). The plastic wrap containing PVC must be used with caution!

The third is polyvinylidene chloride (PVDC for short), which is mainly used for packaging some cooked food, ham and other products. PVDC food cling film: excellent resistance to oxygen, odor and moisture, and high heat resistance temperature. It can also be used for microwave heating. However, it is suggested that you should pay attention to choosing the food cling film that is indicated to be applicable to the microwave oven when purchasing. If there is no suggestion, please do not cook or heat in the microwave oven.

Among the three kinds of food cling film, PE and PVDC are safe for human body and can be used at ease, while PVC food cling film contains carcinogens, which are harmful to human body, so it must be used with caution! Because PVDC is relatively expensive, PE is the main preservative film in the market. Therefore, PE food cling film should be selected when purchasing food cling film.

From the physical point of view, the food cling film has moderate oxygen permeability and moisture permeability, regulates the oxygen and water content around the fresh-keeping products, blocks dust, and thus extends the fresh-keeping period of food. Therefore, it is necessary to choose different food cling film for different foods. Therefore, ChangLong brand PE food cling film equipment is selected for the production of PE food cling film.
