Many people are very particular about packing things in plastic bags, especially when packing food stuffs. It should be understood that plastic bags have great differences in the manufacturing ingredients. In terms of ingredients, there are many different raw materials. In fact, if it is used to hold other things, the degree of attention to raw materials is very low. But if it is used for food, many people are very particular about it. Because of this, when it comes to food bags, the first thing everyone will think of is the PE ingredient. Now let us understand together whether PE plastic bags can be used to hold food and how safe they are.
The so-called PE is polyethylene. In the case of PE, there is no poison. And basically 90% of the plastic bags are processed from raw materials such as polyethylene. The main feature of this kind of plastic bags is that they cannot hold food that is too high temperature. Putting food at too high temperature will cause certain toxicity. Some people may not have a clear understanding of this point. It is important to know that if the food exceeds 90 degrees, it will produce different chemical projections. During the whole process, substances such as chlorine will be released, which will cause certain toxicity to our body. Over time, it will cause cancer. Because of this, if you want to use PE plastic bags, you must avoid using them at high temperatures, otherwise it will cause some harm to your body.
Can PE plastic bags be used for food? The answer is yes. It can be used to pack food that is weighed in bulk, or it can be used to pack food that has not been packaged. But it is necessary to ensure that these unpackaged foods are in a state of normal temperature if they are above the temperature. Only in this case, your plastic bag is safe.
In fact, in the selection of raw materials, plastic bags generally choose the safer raw materials, which can effectively ensure the safety during use. But for some users, when using plastic bags, they must pay attention to the temperature of the food packaging. Warm food is best to wait for it to cool before putting it in a plastic bag, otherwise it will cause adverse reactions. This is the case with PE plastic bags.
Many people may say that they don’t understand PE plastic bags. In fact, such plastic bags can be seen everywhere in our lives. For example, the fresh-keeping bags, insurance plastic bags, etc. we see in supermarkets are all made of PE. Why is this material so popular? There are two important reasons. One is that this material is non-toxic and tasteless, and basically does not cause any side effects during use. Furthermore, if this material is used and in the production process, the input cost is relatively small, which can effectively reduce the entire production cost. This is why this kind of plastic bag is so common and popular.
