Product Introduction – What Is TPU Dry Bag Fabric?
TPU dry bag fabric is produced by coating polyester or nylon base cloth with thermoplastic polyurethane (TPU). TPU is widely known for its exceptional elasticity, high tensile strength, and superior resistance to cold environments and abrasion.
TPU is considered a premium eco-friendly alternative to PVC, especially for brands requiring lightweight and high-performance waterproof materials. DERFLEX TPU dry bag fabric is ideal for professional outdoor gear manufacturers who prioritize comfort, durability, and environmental sustainability.

Product Features – Advantages of TPU Dry Bag Fabric
1. Superior Flexibility & Elasticity
TPU dry bag material remains flexible even under extremely low temperatures. It will not stiffen, crack, or weaken in winter or high-altitude environments.
2. 100% Waterproof and Airtight
High-resilience TPU coating forms a strong waterproof barrier with outstanding hydrostatic resistance, making it ideal for dry bags and inflatable applications.
3. Lightweight & Comfortable
TPU is significantly lighter than PVC while maintaining better strength, making the user experience more comfortable for long-term outdoor usage.
4. Eco-Friendly Material
The fabric meets global environmental standards (ROHS, REACH) and contains no plasticizers, chlorine, or harmful chemicals.
5. Exceptional Abrasion Resistance
Recommended for heavy-duty river bags and kayaking bags that require strong scratch protection.
6. Excellent Weldability
TPU accepts high-frequency welding, hot-air welding, and ultrasonic bonding, ensuring high-quality seamless construction.
