How to keep plastic packaging bags longer
Plastic bags are closely related to our lives, especially now that there is no product that can replace plastic bags. In particular, the food bags in which we store food have a profound impact on the health and safety of our food. But many food bags look the same after use but have undergone some changes. The following editor will tell you how to avoid the aging of food bags?
1. In the natural environment, that is, under the condition of direct sunlight, the strength of the food plastic packaging bag will drop by about 25% after one week, and will drop by about 40% after two weeks, and it is basically unusable. That is to say, the storage and storage of plastic bags is very important.
2. After packaging the items, the packaging bag will be exposed to direct sunlight in the open air, and the intensity will drop sharply, so try to avoid direct sunlight.
3. The excessive participation of recycled materials is also one of the reasons for promoting the aging of plastic packaging bags.
4. During the storage and transportation of the packaging bag, the temperature is too high or it encounters rain, which will cause its strength to decrease, and then it will not meet the quality requirements for maintaining the contents of the package. Therefore, high temperature and rain should be avoided in normal times.
