Plastic packaging bags for food are closely related to our life. At present, there is no product that can completely replace it, but how much do you know about it? Do you know how to prevent it from aging? Next, I would like to introduce some tips on how to prevent the aging of food packaging bags.
1. In the natural environment, that is, under the condition of direct sunlight, the strength of plastic packaging bags for food will decrease by about 25% after one week and by about 40% after two weeks, which is basically out of use. In other words, the storage of plastic packaging bags is very important.
2. The packaging bag shall be placed in the open air and exposed to direct sunlight after packaging, and the intensity will drop sharply, so the direct sunlight shall be avoided as far as possible.
3. Excessive participation of recycled materials is also one of the reasons to promote the aging of plastic packaging bags.
4. In the process of storage and transportation, if the temperature of the packing bag is too high or it encounters rain, its strength will decrease, and then it will not meet the quality requirements of the maintenance of the contents, so the high temperature and rain wash should be avoided at ordinary times.
