Organic fertilizer valve paper bag is a packaging bag designed specifically for powdered and granular materials such as organic fertilizers, fertilizers, mineral powders, etc. Its core feature is the "valve" structure at the bottom or side. This structure automatically opens during filling and closes after the material is filled, forming a seal that effectively prevents leakage and moisture. This design not only improves packaging efficiency, but also ensures the safety and stability of materials during transportation and storage.
