PVC Coated Fabric for Inflatable Flood Control Bags

Introduction

Flood control bags are important flood control emergency supplies, and their materials directly affect the effectiveness of rescue and disaster relief. Although traditional sandbags are low in cost, they have some pain points such as being heavy, prone to damage and not reusable. Inflatable flood control bags made of PVC coated fabric have unique material advantages. Now let's take a look at the core advantages of PVC coated fabric flood control bags together to provide professional references for purchasing decisions.

The advantages of PVC coated fabric

Super waterproof barrier

Through high-precision coating technology, PVC material forms a continuous protective layer of 0.3-0.8mm on the surface of the base fabric. It has been verified by water pressure testing that it can withstand a pressure of ≥50kPa (equivalent to the pressure of 5 meters of water column), ensuring absolute anti-permeation. Its closed-cell structure can effectively prevent water penetration and maintain zero leakage during the 72-hour immersion test.

Outstanding mechanical strength

The material is made of 500-1000D high-density polyester fiber base fabric, combined with a double-sided PVC coating process, to achieve a tear resistance strength of 80-120N/cm². Laboratory data shows that it can withstand a continuous pressure of 1.5 tons per square meter when inflated without bursting.

Environmental tolerance capacity

Temperature adaptability: Physical properties remain stable in an environment ranging from -40℃ to +100℃

Anti-biological erosion: Passed the ISO 846 microbiological test and effectively resists mold growth

Flexible processing characteristics

The heat sealing strength reaches 50N/15mm

It supports various processing methods such as high-frequency welding and hot air sewing

Customizable colors (RAL color card) and surface treatments (matte/glossy)

Economic advantage

Compared with rubber-coated materials, the cost of PVC-coated fabrics is reduced by approximately 35%, and the production energy consumption is decreased by 40%. The service life can reach 8 to 10 years (under normal usage conditions), and the average annual usage cost is only 1/5 of that of traditional sandbags.

Rapid response capability

Deployment speed: A team of 3 people can build a 10-meter flood wall within 15 minutes (traditional sandbags require 6 people for 2 hours)

Folding volume: After inflation, the volume expands 50 times and the storage space is saved by 80%

Motor transportation: A standard 20-foot container can carry 2,000 uninflated units (equivalent to the capacity of 40,000 sandbags)

Conclusion

Inflatable flood control bags made of high-quality PVC coated fabric are reliable flood control barriers and also important infrastructure investments. In fact, with the continuous advancement of material technology, the performance of PVC coated fabrics in practical applications has become more prominent. PVC coated fabric is redefining the performance standards of flood control equipment and providing innovative solutions for urban flood control efforts.
