What Is Double-Sided TPU-Coated Nylon Fabric?
Double-sided TPU-coated nylon fabric is a technical composite textile made by bonding thermoplastic polyurethane to both sides of a nylon base fabric. The nylon provides tensile and tear strength, while the TPU layers provide waterproofing, airtightness, weldability, elasticity, abrasion resistance and chemical protection.
Two-Side Sealing Surface
TPU on both sides gives product designers more flexibility for welding, folding, bonding, reinforcement patches and airtight seam construction.
Nylon Reinforcement Core
Nylon ripstop or high-tenacity woven fabric provides strength, puncture resistance and lightweight performance for inflatable and outdoor gear.
Premium TPU Protection
TPU improves cold flexibility, abrasion resistance, elasticity and environmental performance, making it a preferred choice for high-end outdoor equipment.
More Reliable for Airtight, Welded and Waterproof Products
For products such as packrafts, air mattresses, inflatable seats, dry bags and waterproof backpacks, material failure often happens at seams, folds, welded corners, abrasion zones or high-pressure areas. Double-sided TPU-coated nylon helps improve product reliability by giving both surfaces a functional TPU layer.
- Better sealing surface for heat welding and high-frequency welding
- Improved waterproof and airtight performance from both sides
- More flexible product design for patches, baffles and seam tapes
- Higher resistance to abrasion, folding, moisture and outdoor exposure
- Premium alternative to PVC where low odor, flexibility and eco-compliance matter
Single-Side vs Double-Side TPU
Single-side TPU-coated nylon is suitable for many lightweight bags and simple waterproof applications. Double-side TPU-coated nylon is preferred when both sides need waterproofing, welding ability, airtight sealing or higher durability. For inflatable products, double-side construction often gives manufacturers better processing freedom and more stable seam design.
DERFLEX can help buyers choose between one-side TPU, double-side TPU, TPU laminated nylon,
TPU-coated polyester and heavier industrial TPU composites according to product function,
target weight, welding equipment and cost target.

Applications for Double-Sided TPU-Coated Nylon Fabric
From ultralight inflatable gear to rugged waterproof bags, double-sided TPU nylon provides the combination of strength, sealability and flexibility needed for professional outdoor products.
How to Choose the Right TPU Nylon Grade
The best material is not always the heaviest material. It should match product function, user environment, welding method, packability, safety requirement and target price level.
Choose Denier by Strength
20D–70D grades are suitable for ultralight air products and small waterproof items. 210D–420D grades balance strength and weight. 840D+ grades fit heavy-duty inflatable and rescue products.
Choose TPU Type by Environment
Polyether TPU is recommended for wet, marine and hydrolysis-sensitive use. Polyester TPU can be selected where abrasion and mechanical strength are the main priorities.
Choose Thickness by Pressure
Higher TPU thickness improves sealing and durability, while thinner constructions reduce weight for backpacking, camping and ultralight product designs.
Confirm Welding Method
Hot-air welding, heat sealing, HF welding and ultrasonic welding each require proper TPU formulation, coating thickness and process parameters.
Test Real Product Conditions
Check seam peel strength, inflation pressure, bending fatigue, water immersion, cold flexibility and abrasion before mass production.
Plan Repeat Order Consistency
For OEM brands and distributors, color, surface, width, winding, batch record and packaging must remain consistent across repeat orders.

Check TPU thickness, coating coverage, pinholes, surface defects, color shade and gloss/matte consistency.
Bonding Strength
Test adhesion between TPU layers and nylon base fabric to reduce delamination risk during use.
Welding Performance
Validate temperature window, seam peel strength, pressure resistance and airtightness after welding.
Mechanical Strength
Test tensile strength, tear strength, puncture resistance and abrasion resistance according to application.
Environmental Resistance
Review cold flexibility, hydrolysis resistance, UV aging, water immersion and chemical resistance where required.
Roll & Packaging Control
Confirm width, roll length, edge quality, winding tension, roll label, carton mark and batch traceability.
How DERFLEX Supports Custom TPU Nylon Projects
DERFLEX helps customers move from material idea to tested sample, confirmed specification and stable bulk supply.
Developing a Double-Sided TPU Nylon Material for a Waterproof Outdoor Gear Brand
A waterproof gear brand needed a material that could be used across dry bags, welded backpacks and inflatable accessories. Their previous material created problems with seam strength, folding recovery and color consistency across repeat orders.
DERFLEX helped the buyer compare 210D, 420D and 840D nylon bases with different TPU thicknesses and matte surface options. After welding tests and water-pressure evaluation, the buyer selected a balanced grade for mainstream products and a heavier-duty grade for river bags and marine equipment.
The result was a clearer material system, easier factory processing, better product consistency and stronger brand confidence when launching multiple waterproof product lines.

Double-Sided TPU-Coated Nylon Fabric FAQ
These questions help buyers evaluate material performance, manufacturing feasibility and sourcing details.
What is double-sided TPU-coated nylon fabric?
It is a composite textile made by coating or laminating TPU onto both sides of a nylon base fabric. The nylon provides strength, while the TPU layers provide waterproofing, airtightness, weldability, abrasion resistance and flexibility.
What is the difference between single-sided and double-sided TPU nylon?
Single-sided TPU nylon has TPU on one side only and is suitable for many waterproof bags and lightweight products. Double-sided TPU nylon has TPU on both sides, making it more suitable for airtight inflatables, welded seams, reinforcement patches and products where both surfaces need waterproof performance.
Can this fabric be heat sealed?
Yes. Double-sided TPU-coated nylon is designed for heat sealing, hot-air welding, high-frequency welding or ultrasonic welding depending on the selected grade. Sample testing is recommended before bulk production.
Which denier should I choose for packrafts?
Packraft fabric selection depends on target weight, durability, pressure, river environment and product design. Lightweight designs may use lower denier nylon, while more rugged packrafts usually require stronger 210D, 420D, 840D or customized high-tenacity constructions.
Is TPU better than PVC for outdoor inflatable products?
TPU is often preferred for premium outdoor gear because it offers better flexibility, lower odor, better cold resistance, high abrasion resistance and improved environmental performance compared with many PVC materials. PVC may still be selected for cost-sensitive heavy-duty products.
Can DERFLEX customize color and surface finish?
Yes. DERFLEX can customize color, matte or glossy surface, TPU thickness, nylon denier, width, roll length, coating weight, packaging, roll label and OEM carton mark according to project requirements.
How should buyers test TPU-coated nylon before bulk order?
Buyers should test welding temperature, seam peel strength, airtightness, waterproofness, abrasion resistance, folding recovery, cold flexibility, pressure holding and final product performance under real use conditions.
How can I request a quote from DERFLEX?
