Floating Dry Bag Fabric (TPU/PVC) – Premium Waterproof Floating Bag Material Manufacturer
DERFLEX is a leading China manufacturer specializing in floating dry bag fabric for outdoor gear producers, marine equipment brands, and waterproof product factories. With more than 20 years of industrial coated fabric experience, DERFLEX provides customized TPU coated fabric, PVC coated fabric, and laminated composite materials used for floating dry bags, river bags, kayaking waterproof bags, and adventure travel equipment.
Our floating dry bag fabrics are designed to offer excellent buoyancy, waterproof performance, tear resistance, and UV stability, ensuring reliable protection for valuable items in extreme outdoor environments.
What Is Floating Dry Bag Fabric?
Floating dry bag fabric is a specialized waterproof coated textile designed for manufacturing floating bags and waterproof dry bags. Compared to traditional tarpaulin materials, floating dry bag fabrics incorporate:
- Advanced TPU or PVC coating for full waterproof sealing
- Special buoyancy layers under optional construction
- High-frequency weldable surface for airtight seams
- Lightweight & portable characteristics
These unique features make floating dry bag fabric ideal for applications such as river trekking, rafting, kayaking, paddle boarding, diving, water rescue gear, and other outdoor adventure sports.
Main Features of DERFLEX Floating Dry Bag Fabric
1. 100% Waterproof & Airtight Performance
Our TPU and PVC coating layers provide outstanding waterproof durability. The fabric is weldable using HF welding, hot air welding, heat sealing, enabling airtight bags capable of floating for long periods.
2. High Buoyancy for Floating Applications
DERFLEX floating materials maintain buoyancy due to:
- Low-density coating formula
- Stable molecular structure preventing water absorption
- Optional internal foam layer or composite structure
3. Superior Tear and Abrasion Resistance
Outdoor dry bags require strong resistance to rocks, sand, water impact, and exposure. Our reinforced base fabrics such as 1000D polyester or 420D/840D nylon deliver industry-leading strength.
4. UV & Weather Resistance
For marine & outdoor use, UV protection is crucial. DERFLEX integrates anti-aging additives:
- UV stabilizers
- Anti-yellowing agents
- Hydrolysis-resistant TPU formula
5. Lightweight & Flexible
Even with strong structural integrity, floating dry bag fabric remains lightweight and easy to roll, fold, and store.
6. Excellent Weldability
Compatible with:
- RF / High-frequency welding
- Hot air welding
- Ultrasonic welding
- Hot pressing lamination
This makes mass production highly efficient and consistent.
