What are the precautions for using PE cling film?

The development prospects of the PE cling film industry are promising, as it brings numerous benefits to businesses when used, thus earning its favor among customers. To help more people understand it, let's delve into the precautions for using PE cling film.

Nowadays, many people are unaware of some basic information about PE plastic wrap, so as a manufacturer, it is necessary for us to briefly explain. In fact, it is important to pay attention to whether the PE plastic wrap is labeled with a specific name or chemical structural formula. If there is only an English name without a Chinese label, please exercise caution when purchasing. Also, remember to choose products labeled with the word "edible". Currently, products are mainly made of polyethylene and polypropylene, and the prices of the two products are not significantly different, but polypropylene can better prevent oil and liquid penetration. When purchasing, it is recommended to buy PE plastic wrap, especially for preserving meat, fruits, etc., because this material is relatively safe in terms of safety. If you want to preserve for a longer period, it is recommended to choose polyvinylidene chloride, because this material has better moisture retention in the preservation layer and has a longer preservation period among the three materials. Of course, it is mainly because of its good transparency, good adhesion, good flexibility, and relatively low price that it has become the choice of many people. However, it should be noted that it cannot be used to preserve oily foods because it is made of polyvinyl chloride. The resin, which consists of resin, plasticizer, and anti-aging agent, is not toxic itself.

However, the main auxiliary materials added, such as plasticizers and anti-aging agents, are toxic. In daily use, polyvinyl chloride (PVC) plasticizers are used, mainly including dibutyl terephthalate and dioctyl phthalate. These chemicals are toxic, and the fat in food can easily dissolve the plasticizer "acetaldehyde" in the plastic wrap, which has a significant destructive effect on the human endocrine system and disrupts hormone metabolism. Of course, when choosing PE plastic wrap, it is important to know that the anti-aging agent lead stearate in PVC is also toxic. When PVC products containing salt-based anti-aging agents come into contact with solvents such as ethanol and ether, lead is released. When PVC products containing lead salts are used for food packaging and come into contact with deep-fried dough sticks, fried bread, fried fish, cooked meat products, cakes, and Dim sum, lead molecules can diffuse into the oil. Therefore, PE plastic wrap cannot be used for this purpose. Chloride plastic bags contain fatty foods. Additionally, do not heat them in a microwave or use them at high temperatures. Because PE plastic wrap products slowly decompose into hydrogen chloride gas at high temperatures, such as 50°C, which is harmful to humans, they are not suitable for food packaging.

After the introduction through the above content, we have gained a deeper understanding of the precautions for using PE cling film. We will no longer feel unfamiliar when encountering it in the future, and there will be fewer issues during its use. Alright, that concludes today's content. I believe it will bring more exciting knowledge points.
