Frequently Asked Questions

Q: How does the "PVC waterproof fabric" of the product ensure the sealing and pressure-bearing capacity of the water bag?
A: The core lies in the dual protection of "double-sided coating + high-frequency welding." The material is a composite of high-strength polyester base fabric and double-sided PVC coating, achieving a hydrostatic pressure value of 0.3MPa (no leakage for 3 hours). Combined with the high-frequency welding process, it enables seamless fusion, eliminating leakage at the source. Additionally, the peel strength exceeds 148N/5cm, ensuring the weld seam does not delaminate under pressure.
Q: As a "flexible water storage container," what data supports the material's tear resistance and environmental friendliness?
A: In terms of mechanical properties, the warp/weft tear strength can reach up to 1080/1124N, with exceptional puncture resistance to effectively guard against damage from sharp objects. Regarding environmental and safety aspects, if used for storing drinking water, food-grade materials certified under FDA 21 CFR 177.2600 must be selected to ensure non-toxicity, harmlessness, and water quality safety.
Q: How does the weather resistance of materials perform in extreme outdoor conditions?
A: Adaptable for global multi-climate operations. With a temperature resistance range from -30°C to +70°C, it maintains flexibility in extreme cold and resists softening or deformation under high temperatures. Additionally, the material passes UV aging tests (≥2000 hours) and incorporates anti-mold treatment, effectively resisting sun exposure, rain, and microbial erosion, with an outdoor service life typically lasting 6-8 years.  R1: "Anti-aging" must be translated as anti-aging.
