Plastic packaging bags have been widely used in all aspects of our lives. In the process of using plastic packaging bags, they are often exposed to wind and sun, and they often gradually deteriorate. What measures should we usually take to avoid the aging of plastic packaging bags? How to use packaging bags effectively?
In the natural environment, that is, under direct sunlight, the strength of plastic packaging bags will drop by 25% after one week, and by 40% after two weeks, basically it can no longer be used. That is to say, the storage and storage of plastic packaging bags is very important.
After plastic packaging cement is placed in an open environment and exposed to direct sunlight, the strength will drop sharply. Excessive temperature during storage and transportation of plastic packaging bags (container transportation) or exposure to rain will cause their strength to decrease, and then they will not meet the quality requirements for protecting the contents.
Excessive participation of recycled materials is also one of the reasons that promote the aging of plastic packaging bags. It has been widely used in food, medicine, chemical and other fields, and the current greening of plastic packaging bags has also become an important development trend.
