If the ton bag is used for a long time, the ton bag will show different degrees of aging, so how can the ton bag manufacturer avoid it?
Reasons for the aging of large bags:
Ultraviolet light is the main reason, because large bags are exposed to sunlight no matter in storage, transportation, use, etc. Ultraviolet rays in sunlight have high energy and can promote the production of free radicals and hydroxides, thereby triggering polypropylene. The molecular chain is broken, so the big bag shows the weakening of tensile capacity and so on. In addition, the differences in local temperature and humidity should also be considered. Mechanism of self-oxidation. Oxygen molecules in plastic boxes are undergoing self-oxidation all the time, and self-oxidation will reduce the molecular weight of plastics, resulting in aging.
Ways to avoid the aging of big bags:
Waterproof and moisture-proof problems when using large bags. The large bags should be dried immediately after use. During use, acidic substances should be prevented from contacting the large bags. When transporting acidic substances, acidic substances need to be removed. The material is well packaged. It is not possible to place the big bag in a place exposed to sunlight, because long-term sunlight will directly cause damage to the big bag. The sun contains ultraviolet rays, and ultraviolet rays will directly oxidize the polypropylene material. When using big bags for transportation or When storing goods, it is necessary to avoid long-term sunlight exposure. Only in this way can the service life of the big bag be ensured.
