Bag’s feature and application

Small Polypropylene woven bags and big bags can be used for sand bags in many applications and are normally filled with sand or soil. Filled sand bags have the right weight and dimensions to build an blocked wall. They often used in emergencies, such as Rivers overflowing, Heavy flooding and levee damage. These bags are suitable for the following applications:

● For Flood control

● For Erosion control

● For Pipelines

● For Oil Field Drilling

● For Military Fortification

● For Construction Sites (Such as Bridge pre-loading)

Sand bags are available with or without UV inhibitor. If the bags are only used single time or eventually buried under earth or sea bottom, a UV inhibitor is not necessary - such as used with pipelines. On the other hand, if the bags used for multi-use or outside under sunlight, it should be with UV inhibitor.

Except for construction materials, they can be widely used in different fields. Such as Chemicals, plastic raw materials, Agriculture products, Mineral products, Firewood and other types of powder, granules, block goods packaging.
