Plastic bags are closely related to our life, especially now there is no product that can replace plastic bags. In particular, our food bags have a great impact on our food health and safety. But many food bags look the same after use, but some changes have taken place. Let's talk about how to prevent food bags from aging?
1. In the natural environment, i.e. in direct sunlight, the strength of food plastic packaging bags will drop by about 25% after one week and by about 40% after two weeks, which is basically no longer available. That is to say, the storage of plastic packaging bags is very important.
2. The packaging bag will be exposed to direct sunlight in the open air after the articles are packed, 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. In the process of storage and transportation, high temperature or rain will reduce the strength of the packaging bag, and then fail to meet the quality requirements for maintaining the contents. Therefore, in normal times, high temperature and rain should be avoided.
