I ask your company on the aging of woven bags how to solve?
Woven bags in natural conditions, that is, under direct sunlight conditions, after a week its intensity decreased by 25%, two weeks later will be reduced by 40%, basically can not be used. That is to say, the issue of storage and storage of plastic woven bags is very important. In addition, plastic woven bags placed in the open air after the environment by direct sunlight, the intensity will be a sharp decline; storage temperature during transport (container transport) or encounter rain, will lead to the decline in its strength, so as to reach the protection Quality requirements for built-in items. Therefore, plastic woven bag transport storage conditions are very important. Therefore, GB / T8946 and GB / T8947 have clear provisions on the storage and transportation conditions, that is, plastic woven bags should be placed in a cool and clean indoor storage, transportation should avoid the sun and rain, should not be close to heat, storage period of not more than 18 month. In fact, the plastic woven bags may be aged in 18 months, so the effective period of the plastic woven bags should be shortened, which should be 12 months.
