What Is TPU Coated Polyester Fabric?
TPU coated polyester fabric is a technical composite material made by applying or bonding thermoplastic polyurethane to a polyester textile substrate. Polyester contributes tensile strength, dimensional stability and lower stretch, while the TPU layer forms a continuous surface for waterproofing, airtight sealing, abrasion resistance and weldable fabrication.
Compared with a generic coated fabric selection, a polyester-based TPU structure is often chosen when the finished product needs roll-to-roll consistency, stable cutting dimensions, controlled elongation and reliable welding in repeated production. It is especially useful for B2B manufacturers who convert fabric into sealed bags, flexible tanks, protective panels, cushions or inflatable chambers.
DERFLEX can discuss both TPU coated fabric and TPU laminated fabric directions. The right construction depends on product size, target weight, seam design, liquid or air contact, operating temperature and the equipment used by the buyer.
Why buyers choose a polyester base
- Better dimensional stability for cutting, laying, welding and repeat production.
- Practical balance of strength, processability and material cost for industrial products.
- Good option for TPU coated polyester rolls used in bags, covers, bladders and containers.
- Available with matte, glossy, embossed or textile-feel surfaces after project review.
- Can be specified as lightweight, medium-duty or heavy-duty depending on end use.
Where TPU Coated Polyester Fabric Is Used
Different applications require different coating thickness, base denier, seam strength and surface finish. DERFLEX helps customers define the material by final product performance rather than by name alone.
Waterproof Bags & Dry Bags
Heat sealable TPU coated polyester fabric for roll-top bags, outdoor dry bags, waterproof storage sacks and welded packing products where surface appearance and folding feel matter.
Inflatable Air Bladders
Double-side TPU coated polyester can be considered for air cells, inflatable cushions and pressure chambers where seam route, air retention and repeat folding need testing.
Medical Air Products
TPU coated polyester for medical air mattresses, pressure-relief cushions and inflatable support structures requiring a cleanable surface and reliable sealed seams.
Flexible Tanks & Oil Bladders
Heavy-duty TPU coated polyester material for liquid-holding products, containment berms and flexible storage systems after compatibility testing with the target liquid.
Industrial Covers & Protective Sheets
Waterproof TPU coated polyester rolls for protective covers, equipment bags, foldable sheets and special fabricated products that require stable dimensions.
OEM Technical Textile Programs

Custom TPU Coated Polyester Fabric Options
The table below is a selection guide for quotation and sampling. Final values should be confirmed by product design, welding trials and application testing.
| Item | Available Direction | Buyer Selection Notes |
|---|---|---|
| Product Name | TPU Coated Polyester Fabric / TPU Polyester Fabric / Weldable TPU Polyester Roll | Use the final application and welding process to define the exact material structure. |
| Base Fabric | Polyester woven fabric; common directions include 210D, 420D, 600D, 840D, 1000D, 1300D, 1500D and custom structures. | Higher denier can support stronger products, but it also changes folding feel, roll weight and welding behavior. |
| TPU Coating Side | Single-side TPU coating or double-side TPU coating. | Single-side coating is useful for covers and bags; double-side coating is often discussed for air-holding or liquid-holding products. |
| TPU Chemistry Direction | Polyether TPU or polyester TPU selection according to water contact, hydrolysis concern, abrasion, oil contact and mechanical strength targets. | Send the working environment and contact media for more accurate recommendation. |
| Weight / Thickness | Lightweight to heavy-duty constructions can be customized. | Do not choose only by GSM. Consider pressure, folding cycle, tank size, weld width, seam design and service environment. |
| Width | Common roll widths and custom width discussion available according to production line capability. | Wider rolls can reduce seams in large products, but packing, inspection and handling need review. |
| Surface Finish | Matte, glossy, embossed, anti-slip texture or textile-feel surface after project review. | Surface finish affects welding contact, cleaning, appearance, hand feel and anti-slip performance. |
| Color / Branding | Custom color matching, printing surface discussion, roll label and OEM package control. | Provide target color, sample, Pantone reference or brand standard when requesting samples. |
| Processing Method | HF/RF welding, hot-air welding, heat sealing, ultrasonic welding or combined fabrication. | Confirm through sample welding before bulk order because seam strength depends on equipment, pressure, time and temperature. |
| Testing Direction | Waterproofing, air retention, peel strength, tensile strength, tear strength, abrasion, puncture, cold flex and compatibility checks. | DERFLEX can support sampling direction; final product validation should be completed by the finished-product manufacturer. |
TPU Coated Polyester vs TPU Coated Nylon vs PVC Coated Fabric
DERFLEX supplies different coated fabric directions, so the recommendation can be based on the finished product instead of forcing every project into one material.
| Material Direction | Typical Strength | Common Applications | When to Discuss This Option |
|---|---|---|---|
| TPU Coated Polyester Fabric | Stable dimensions, practical strength-cost balance, waterproof and weldable TPU surface. | Waterproof bags, covers, flexible containers, medical air products, industrial sheets and selected bladders. | Choose when dimensional stability, roll consistency and OEM fabrication control are important. |
| TPU Coated Nylon Fabric | Soft folding, high tear performance direction, lightweight feel and strong flexibility. | Inflatable boats, packrafts, rescue gear, dry bags, sports products and lightweight airtight products. | Discuss when the product needs soft folding and tear strength in a lighter structure. |
| TPU Laminated Fabric | TPU film laminated to a textile substrate for a controlled film layer and selected surface appearance. | Waterproof textiles, bags, technical layers, outdoor gear and lamination-based OEM products. | Consider when film thickness control, hand feel or lamination appearance is part of the design. |
| PVC Coated Fabric | Heavy-duty waterproofing, broad industrial use and cost efficiency for large covers. | Truck tarps, tents, awnings, industrial covers, tarpaulin rolls and membrane structures. | Choose for large-format industrial covers where TPU-level air holding or soft folding is not the main priority. |
