Reasons for the aging of food packaging bags and preservation techniques

Food plastic packaging bags are closely related to our lives. 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? Let me introduce the food packaging bag to prevent this problem. Aging tips.
 
1. In the natural environment, under the conditions of direct sunlight, the plastic packaging bag will decrease its strength by about 25% after one week, and will decrease by about 40% after two weeks. Basically, it cannot be used. That is to say, the storage and storage of plastic bags is very important.
 
2. The packaged bag is placed in the open air environment and exposed to direct sunlight after being packaged. The intensity will drop sharply, so try to avoid direct sunlight.
 
3. Excessive participation of recycled materials is also one of the reasons for promoting the aging of plastic packaging bags.
 
4. If the temperature is too high or the rain is encountered during the storage and transportation of the packaging bag, the strength will be reduced, and then the quality requirements for the maintenance of the contents should not be met. Therefore, the high temperature and the scouring of the rain should be avoided.
