PVC waterproof bags are based on polyvinyl chloride (PVC) coated fabric and achieve seamless sealing through heat sealing technology. Their main advantage lies in their waterproof and leak-proof properties. The tight molecular structure of PVC makes it difficult for water molecules to penetrate, allowing it to withstand heavy rain and humid environments.
PVC waterproof bags are often used for packaging outdoor advertising materials and as promotional materials. They can be printed on, clearly displaying advertisements and serving a promotional purpose. Even after exposure to wind, sun, and rain, they can maintain their vibrant colors. In addition, three-dimensional shapes can be customized through hot-pressing technology, such as hanging display bags, enhancing advertising appeal.
PVC water storage bags (also known as water bladders) can store 500-50000 liters of water and are used in: Mountain irrigation: In water-scarce areas, water storage bags, combined with drip irrigation systems, supply water to farmland, reducing evaporation losses.
Livestock drinking water: Livestock farms use foldable water bladders, which are regularly inflated to store clean water, reducing transportation costs.
Firefighting water storage: Large PVC water bladders can be quickly deployed at disaster sites, storing 2 tons of drinking water at a time.
Temporary toilet construction: Inflatable isolation chambers are used in disaster relief camps, with leak-proof designs to ensure hygiene and safety.
Underground pipeline inspection: Inflatable water bladders are used for pipeline pressure testing, quickly locating leakage points.
Flood control embankment reinforcement: Modular water storage bags are stacked to form temporary flood control walls, resisting small to medium-sized floods.
Chemical raw material storage: Corrosion-resistant PVC water bladders can carry acid and alkali solutions, replacing metal tanks and reducing the risk of leakage.
Edible oil transportation: Food-grade TPU/PVC composite bags are FDA certified to ensure hygiene and safety.
