NSF/ANSI 61 Potable Water Liner

At Plastic Film Corporation, we provide NSF/ANSI 61 potable water liners designed for large-volume storage systems. 

These RF weldable water linings deliver exceptional durability and safety for tanks storing 500 gallons or more. 

Our NSF/ANSI 61-certified materials offer a robust, contamination-resistant barrier, ensuring your stored water is safe and maintained with the highest standards of integrity.

Supporting Safe Storage with NSF/ANSI 61 Potable Water Liners

NSF/ANSI 61 potable water liners are essential for ensuring the safety and integrity of water storage systems. These liners are designed with flexibility, weld strength, and compliance in mind, guaranteeing long-term, reliable performance across a variety of storage needs.

Made from high-quality PVC, our liners contain no additives that could leach into the water. This formulation maintains flexibility under temperature shifts, resists warping or burning during the RF welding process, and ensures a clean, consistent weld seam. The end result is leak-free performance and a predictable long-term storage solution, making it the ideal choice for potable water storage.

Material Options to Meet Storage Needs

We understand that each water storage system is unique, which is why we offer a variety of material options within the NSF/ANSI 61 potable water liner product family. These options allow for customization based on the specific requirements of your project. Whether you need varying thicknesses, widths, or reinforcements, our liners are designed to provide seamless RF welding and ensure durability for long-term potable water storage.

Standard PVC Gauges

Our standard PVC gauges are designed for smooth handling and reliable weld performance. These products are well-suited for tank fabricators, field teams, and OEMs needing consistent, flexible material for large-scale projects. Available gauges include:

  • SKU NSF-3060W – .030" gauge, 60" width, 110-yard rolls
  • SKU NSF-4060W – .040" gauge, 60" width, 85-yard rolls
  • SKU NSF-6060W – .060" gauge, 60" width, 55-yard rolls

These materials ensure ease of handling, reliable welds, and dependable performance in a variety of applications.

Wider PVC Gauges

For projects requiring extra strength or wider sheets, we offer wider PVC gauges that increase coverage, streamline installation, and maintain uniform performance across tanks with larger surface areas or specialized geometries:

  • SKU NSF-3072WS – .030" gauge, 72" width, 95-yard rolls
  • SKU NSF-4072WS – .040" gauge, 72" width, 75-yard rolls

These wider gauges help improve overall efficiency during installation, reducing the need for additional seams and maintaining consistent performance even in tanks with more complex geometries.

Why PVC Construction Matters in Potable Water Storage

PVC is the preferred material for potable water storage for several key reasons. Its chemical resistance, weld strength, and dimensional stability under pressure make it an ideal choice for tanks exposed to fluctuating temperatures and heavy usage.

PVC maintains its form even under hydrostatic pressure, resists wear from fill-and-drain cycles, and performs consistently under vibration or rapid temperature changes. Whether it’s for municipal use, industrial applications, or agricultural tanks, PVC water liners provide a stable and reliable solution.

Additionally, PVC’s flexibility and ease of handling allow for custom tank shapes and precise construction. Fabricators can create tanks that meet specific dimensions and geometries while adhering to NSF/ANSI 61 compliance, providing control over seams, transitions, and penetrations without compromising the safety of the stored water.

Industries That Benefit from NSF Potable Water Tank Liners

Our NSF/ANSI 61 potable water tank liners serve a diverse range of industries, each of which benefits from high-quality, reliable water storage solutions.

Emergency and Humanitarian Use

For aid organizations and emergency teams, reliable water storage is a critical part of disaster relief efforts. Our RF weldable materials make it easy to create temporary reservoirs quickly, providing clean, safe water for vulnerable communities during humanitarian crises.

Industrial Facilities

Industrial operations, whether used for cooling, rinsing, or mixing, require reliable, high-purity water storage. Our NSF potable water tank liners help maintain the integrity of water reserves while safeguarding production lines and equipment. Custom liners can be made for vertical tanks, horizontal tanks, open reservoirs, or temporary storage during maintenance, ensuring continuity in industrial processes.

Agricultural and Aquaculture Operations

Whether it's for irrigation, hydroponic systems, or fish tanks, agricultural and aquaculture operations require clean, stable water sources. Our NSF/ANSI 61 potable water liner materials provide a contamination-resistant surface that protects livestock, plants, and aquatic species, ensuring healthy operations and optimal growth.

Municipal and Utility Storage

Municipalities and utilities depend on safe, high-quality water storage for both emergency reserves and day-to-day distribution. Our liners are perfect for storing water in pressurized tanks, temporary reservoirs, standpipes, and community distribution systems, providing a secure, leak-free solution that can be quickly deployed when needed.

Construction, Mining, and Remote Sites

In construction, mining, and remote sites, access to water for drinking, dust control, and sanitation is essential. Our flexible PVC liners can be easily transported and installed, providing a long-lasting, cost-effective solution to meet the needs of projects in rugged conditions, even in areas without established utilities.

How We Support Fabrication and Installation Work

At Plastic Film Corporation, we do more than just supply materials—we ensure your fabrication and installation processes run smoothly. With dependable roll lengths, clean edges, and consistent batch performance, our products make installations faster and more efficient.

For fabricators, our materials are designed to provide predictable shrink rates, consistent thickness, and steady torch control for reliable welds. For field teams, the lightweight nature of the material ensures easier handling and faster installation. Crews can easily cut, fold, and attach the material to create custom drops, folded sections, and reinforcement patches without worrying about material failure or stretching.
