Flood prevention woven bag structure Fabric bags are the main materials composed of polypropylene bags and polyethylene bags. Pay attention to the carrying capacity of woven bags when using them. Generally speaking, woven bags can accommodate heavier items, but items that exceed the carrying capacity should be avoided to avoid damaging the woven bag or being unable to carry. If it is heavy and inconvenient to move, do not drag it on the ground to avoid bringing soil into the interior of the woven bag or causing the bag silk formed by the woven bag to crack. During transportation, woven bags should be covered with some waterproof or moisture resistant cloth to avoid direct sunlight or rain corrosion.
