Water absorbent expansion bag

Polymer sap sandbags are new style sandbags that are filled with a polymer material inside that could absorb water and swells, creating a barrier that can help prevent flooding. These sandbags are more effective than traditional sandbags because they can absorb and hold more water, creating a stronger barrier against flooding. The polymer sap sandbags are also more environmentally friendly than traditional sandbags because they can be reused and do not need to be disposed of after use, while the old style sandbags are heavy and easy break and would cause pollution to enviroment. When talking about reusing, have to mention that after first time use,second use effect would be bad, and could only have about 30% to 60% effect as per first time use. The self-inflated bags are commonly used by emergency responders, municipalities, and homeowners to protect against flooding and other water-related disasters, and it could also be used for home and house guard to prevent water, rain and flood problem.
