Causes Of Aging Of Food Ton Bags

When it comes to ton bag products, I believe you should be no stranger, in our lives, you can see its application everywhere, whether it is food packaging, or non-food product packaging. Ton bags as packaging materials, long-term use, there will always be different degrees of aging, we in addition to take good care of it, but also need to know the causes of aging food bags. Only when we know the reason, can we improve the ton bag and produce a better ton bag. Now, the food ton bag manufacturer will analyze the reason for the aging of the ton bag with you.

Causes of aging of food ton bags
1, ultraviolet light is one of the main reasons, because the bag is exposed to more sunlight in storage, transportation, use, etc., the ultraviolet light in the sun has energy, can make free radicals and hydrogen and oxygen compounds, thereby causing the break of the molecular chain in polypropylene, so the bag is manifested as the tensile ability to weaken. In addition to this, there are local differences in temperature and humidity to consider.

2. Auto-oxidation mechanism. The oxygen molecules in the plastic box are constantly undergoing self-oxidation, which will reduce the molecular weight of the plastic, resulting in aging.

3. Photooxidation mechanism. The photooxidation mechanism of sunlight has two sources: first, direct sunlight, direct irradiation of the sun; Second, indirect sunlight, due to the reflection of water vapor in the air, dust, etc.; The two main sources of sunlight contain infrared rays, which cause a variety of oxidants and easily degrade polymers.

Ultraviolet light, autoxidation, photooxidation are all causes of aging that affect the use of food bags, some are natural factors, and some are unnatural factors. Understanding these factors is helpful for the upgrading and improvement of food bags. This also reminds us that we need to take more care of it in the usual use process, this is what we want to understand, want to buy container bags, tons of bags, you can come to our company to understand one or two.
