Collapsible TPU fuel bladder tanks provide portable liquid storage where rigid tanks are difficult to transport, deploy or recover. We supply finished flexible bladders for professional buyers, distributors, equipment integrators and project contractors. Final material, fittings and operating conditions must be confirmed for the actual liquid and use.
Applications: temporary diesel storage, generator fuel supply, mining and construction sites, marine auxiliary fuel, emergency response, transformer oil, lubricants and other compatible industrial liquids.
A TPU fuel bladder tank is a flexible, closed liquid container made from reinforced fabric with a thermoplastic polyurethane coating or laminate. The textile reinforcement carries tensile and handling loads, while the polymer surface provides the liquid-contact barrier and a weldable exterior for forming seams and attaching reinforced fitting zones.
When empty, the bladder can be folded for storage and transport. During use, it expands as liquid is introduced and forms a low-profile pillow shape. The filled geometry depends on nominal capacity, base dimensions, fabric behavior and operating fill level.
The term fuel bladder is used broadly in the market. It can refer to ground-storage bladders, marine auxiliary fuel tanks, vehicle or motorcycle fuel bags, aircraft fuel cells and military tactical systems. This page focuses on finished flexible bladders for professional ground, marine and industrial storage unless a different application is specifically engineered and confirmed.
TPU is not a single universal fuel-resistant material. Performance depends on the TPU formulation, coating structure, base fabric, adhesive or lamination system, weld quality, valves and seals. Diesel, petrol, aviation fuel, lubricants and transformer oils should not be treated as interchangeable.

Specifications vary by liquid, capacity, fabric, fitting system, quantity and application. Final values are subject to the current product-specific drawing, technical data, compatibility review, approved sample and purchase contract.
The bladder body is made from reinforced coated fabric panels joined by controlled welding. The reinforced textile provides strength and dimensional support. The inner polymer surface contacts the liquid, while the outer surface supports welding, handling and environmental protection according to the selected material.
Fittings are installed in reinforced zones because loads concentrate around the inlet, outlet, vent and hose connections. Reinforcement size, fitting material, seal material and location should be matched to the intended hose loads, liquid and operating arrangement.
Step | Production Activity | Information |
1 | Confirm liquid, use, capacity, dimensions, fittings and documents. | Technical review before quotation and drawing. |
2 | Select and inspect the approved coated fabric and fittings. | Batch identity, surface condition and compatibility direction. |
3 | Prepare drawing, panel layout and reinforcement details. | Capacity geometry, seam layout and fitting position. |
4 | Cut body panels and reinforcement patches. | Dimensional accuracy and clean edges. |
5 | Weld panels and fitting reinforcement zones. | Process parameters, overlap and seam consistency. |
6 | Install valves, flanges, vents and accessories. | Correct materials, orientation and sealing. |
7 | Complete visual, dimensional and leak/holding inspection. | Follow the confirmed inspection plan. |
8 | Dry, fold, label and pack the finished bladder. | Cleanliness, traceability and transport protection. |
A fuel bladder is a flexible closed container used for temporary or project-specific liquid storage. It is supplied empty and folded, then deployed on a prepared site and connected to the required filling, discharge and vent system.
Selected TPU-coated reinforced fabrics can be considered for diesel applications. Suitability still depends on the exact diesel, additives, temperature, exposure time, seams, seals and fittings. Send the fuel information before ordering.
Do not assume so. Petrol can create different permeation, swelling, seal and venting requirements. The material and complete product must be reviewed for the actual fuel.
Marine configurations can be discussed for boats, yachts, workboats and unmanned vessels. Provide the fuel, available space, restraint method, fittings, venting and applicable requirements.
Not automatically. Dynamic loads, restraint, sloshing and regulatory requirements may require a different design. State mobile use at the enquiry stage.
Small portable, medium and large project sizes can be discussed. Request the current model list and filled dimensions; do not choose by nominal capacity alone.
Yes, custom footprint and fitting layouts can be reviewed. Provide the required capacity, maximum length/width/height and all connection positions.
Inlet, outlet, vent, return, threaded, flanged and quick-coupling directions may be available. Final options depend on liquid, size and project requirements.
A clean, smooth and protected support surface is important. A suitable groundsheet is commonly recommended to reduce abrasion and contamination risk.
Requirements depend on the liquid, capacity, site and local rules. Many professional fuel-storage applications use a spill berm or bund as part of the system.
Storage duration is project-specific. It depends on compatibility, temperature, exposure, maintenance and the product design. Confirm the intended duration before purchase.
Some localized damage may be repairable using an approved procedure and compatible material. The bladder should be emptied, cleaned and assessed before repair; severe or fitting-zone damage may require factory review.
Drain and clean it according to the liquid and product instructions, allow it to dry as required, fold it correctly and store it in a clean, dry, protected location.
The inspection scope can include material review, visual and dimensional checks, seam controls and agreed finished-product leak or holding tests. Confirm the method and report before ordering.
Available documents depend on the selected product, material, order and current reports. Send the exact document or standard requirement before quotation.
Provide the liquid/SDS, capacity, use mode, temperature, site dimensions, fittings, accessories, quantity, destination and required documents.
Capacity, fabric, liquid compatibility, fittings, custom design, testing, accessories, quantity and packing all affect price.
MOQ depends on model, customization, material and packing. Request the current commercial quotation.

The applications below describe common enquiry directions. They do not mean that one bladder is automatically suitable for every fuel, site or operating method. Confirm the exact liquid, material, fittings, installation, temperature, containment and inspection plan.
Application | Information |
Temporary diesel storage | Deployable fuel storage for construction, agriculture, maintenance, emergency power and remote work sites. Confirm local storage and environmental requirements before filling. |
Generator fuel supply | A flexible bladder can support temporary generator operation where a permanent bulk tank is unavailable. Capacity planning should consider fuel consumption, runtime, refill frequency, filtration and connection to the day tank. |
Mining and remote projects | Folded bladders can be transported to remote sites and deployed on prepared ground with suitable secondary containment. Large projects should include a complete transfer, monitoring and spill-response plan. |
Marine auxiliary fuel | Custom marine bladders can be discussed for boats, yachts, workboats and unmanned vessels. Fuel type, restraint, abrasion protection, venting and system interfaces must be reviewed. |
Transformer oil storage | Temporary storage can be discussed for maintenance and service operations where oil cleanliness, fitting materials and controlled transfer are important. |
Lubricant and industrial oil | Flexible storage may support maintenance, recovery or temporary process needs after the liquid and temperature are reviewed. |
Emergency response | Compact packed storage can support temporary deployment, but the operating team still needs a prepared site, containment, trained handling and an inspection plan. |
Fuel distribution support | Distributors and equipment integrators can combine the bladder with hoses, pumps, filters, meters and containment equipment for a project-specific package. |
