Flexible Bladder Tanks for B2B Project Applications
LonaTarp manufactures custom pillow tanks for temporary liquid storage, project water supply, agricultural irrigation, construction sites, emergency response, rainwater collection, and selected industrial liquid storage applications. A pillow tank, also called a flexible bladder tank or collapsible liquid storage tank, is made from welded coated fabric. When empty, it can be folded for compact transport and storage; when filled, it expands into a low-profile storage tank that can be deployed on prepared ground or project sites.
For B2B buyers, the key question is not only “how many gallons can it hold?” A reliable pillow tank must match the stored liquid, site condition, working temperature, filling method, fitting layout, ground protection, and expected service cycle. These factors directly affect material selection, seam design, fitting reinforcement, and long-term use performance.
LonaTarp mainly recommends heavy-duty PVC-coated polyester fabric for non-potable water storage projects. For projects requiring higher flexibility, better folding performance, low-temperature use, or specific liquid compatibility, alternative coated fabric options can be discussed before production.
Application Scenarios for Pillow Tanks
Pillow tanks are used when project buyers need temporary, movable, or space-saving liquid storage. Different applications require different fabric structures, fitting layouts, ground protection, and material compatibility checks.
Construction Site Water Storage
Agricultural Irrigation Reserve
Emergency Water Supply
Rainwater Harvesting Tank
Firefighting Water Reserve
Industrial & Wastewater Holding
Material Options and Recommended Specifications
Different liquids and working environments require different coated fabric structures. For most non-potable water storage projects, PVC-coated polyester is a practical and cost-effective material direction. For potable water, fuel, oil, chemicals, low-temperature environments, or frequent folding use, material compatibility should be confirmed before quotation and production.
| Specification Factor | LonaTarp Recommended Direction | Why It Matters for B2B Buyers |
|---|---|---|
| Standard Material | 950 GSM PVC-coated polyester, approx. 28.0 oz/yd² | A strong starting material for construction water, irrigation reserve, rainwater collection, and firefighting water storage. |
| Optional Material | TPU-coated fabric can be considered for selected projects | Useful when buyers need higher flexibility, better foldability, low-temperature performance, or specific liquid compatibility. |
| Base Fabric | 1000D × 2000D polyester yarn option | Helps improve tensile strength, but panel direction and main stress points should be considered during tank design. |
| Fabric Structure | 20 × 10 structure, confirmed in technical specifications | Affects tensile strength, puncture resistance, flexibility, coating adhesion, and welding performance. |
| PVC Coating | Continuous liquid-barrier PVC coating, formula confirmed by application | Liquid resistance depends on coating quality, folds, edges, seams, ports, and the stored medium. |
| Welding & Reinforcement | HF welding or hot-air welding with reinforced ports and stress areas | Pillow tank failures often happen around seams or fittings, so welding and reinforcement are as important as GSM. |
| Application Grade | Standard for non-potable water; special confirmation for potable water, fuel, oil, chemicals, or wastewater | Helps buyers avoid wrong material selection, leakage, contamination, swelling, or coating failure. |

Custom Manufacturing for Project Requirements
Every pillow tank should be designed around the actual project site. A construction site may need quick filling and draining. An agricultural project may care more about UV exposure and seasonal reuse. An industrial buyer may need specific ports, valves, ground protection, or material compatibility.
LonaTarp can customize:
Capacity by gallons, liters, or cubic meters
Tank length, width, and height according to site footprint
Coated fabric structure according to application needs
Fill port, drain port, vent, overflow, flange, valve, or camlock connection
Reinforced corners, ports, bottom layer, and stress points
Groundsheet or protective base fabric
Repair kit, storage bag, and accessories
Color, logo printing, and private label packaging
Sample confirmation before bulk production
For large tanks, rough ground, frequent relocation, or longer outdoor exposure, we recommend confirming the full tank structure instead of only increasing fabric GSM.

Pillow tank performance depends on more than storage capacity. Fabric structure, welded seams, reinforced fittings, and ground protection all affect leakage resistance, handling safety, and service life in real project environments.

Liquid Storage Bladder FAQ
What information should I provide before ordering a pillow tank?
Please provide the stored liquid type, required capacity, available site footprint, indoor or outdoor use, ground condition, fitting size, filling and draining method, working temperature, quantity, and destination country.
Can one pillow tank material be used for all liquids?
No. Different liquids require different coated fabric structures. Standard PVC-coated polyester is commonly used for non-potable water, construction water, irrigation reserve, rainwater collection, and firefighting water storage. Potable water, fuel, oil, chemicals, or wastewater require material compatibility confirmation before production.
What GSM do you recommend for PVC pillow tanks?
For heavy-duty non-potable water storage projects, LonaTarp recommends 950 GSM PVC-coated polyester, approx. 28.0 oz/yd², as a strong starting material. Final tank performance also depends on welding, fittings, reinforcement, ground protection, and tank design.
Can you print our Logo?
Yes. Logo artwork, color, print method, placement, seam clearance, folding route and sample approval should be confirmed before bulk production.
Can the pillow tank size and fittings be customized?
Yes. LonaTarp can customize the capacity, length, width, height, fill port, drain port, vent, overflow, flange, valve, camlock connection, reinforced port areas, and groundsheet according to your project requirements.
Is a groundsheet necessary for pillow tank installation?
A groundsheet is strongly recommended for rough ground, outdoor deployment, long-term use, or frequent relocation. It helps reduce abrasion, puncture risk, and direct contact between the tank bottom and sharp surfaces.
Can pillow tanks be used for fuel, oil, or chemicals?
Only after material compatibility is confirmed. Fuel, oil, chemicals, and hazardous liquids may require special coated fabric, fittings, testing, and compliance review. Ordinary PVC-coated fabric should not be assumed suitable for these liquids.
Can I get a sample before bulk production?
Yes. LonaTarp supports sample confirmation before bulk production, including fabric structure, welding, fittings, color, logo printing, and packaging details.
