A Complete Guide to Flexitank Container Shipping: Features, Sizes, Pros & Cons

Did you know that a single flexitank can hold up to 24,000 liters of liquid cargo—enough to fill a swimming pool? Flexitank container shipping has revolutionized the transportation of bulk liquids, offering a flexible, cost-effective, and efficient solution for industries across North, Central and South America.

But what exactly is flexitank container shipping, and why is it gaining popularity? This guide will explore its features, sizes, advantages, disadvantages, and more to help you understand this innovative shipping method. Let’s dive in.

What Is Flexitank Container Shipping?

A flexitank is a single-use, large, flexible bag or bladder specifically designed to transport non-hazardous bulk liquids inside standard  20-foot shipping containers. Constructed primarily from polyethylene and polypropylene, flexitanks convert dry cargo containers into cost-effective liquid transportation solutions.

Flexitank containers are commonly used to transport:

• Food products (oils, wines, juices)
• Industrial chemicals (non-hazardous)
• Agricultural liquids
• Pharmaceuticals

Key Features of Flexitanks

Design & Construction

Flexitanks are typically single-use, composed of multiple layers of food-grade polyethylene with an external polypropylene layer for added strength. This design ensures the liquid remains uncontaminated and secure throughout transit. Designed to fit snugly inside 20-foot containers.

Capacity & Compatibility

Flexitanks usually range from 16,000 to 24,000 liters (approximately 4,227 to 6,340 gallons), fitting neatly into standard 20-foot containers. The most common size used is around 24,000 liters due to its optimal capacity for maximizing space and efficiency. Compatible with non-hazardous liquids (e.g., olive oil, wine, liquid fertilizers).

Single Use of Flexitank Container Shipping

Most flexitanks are disposable, eliminating cleaning costs and contamination risks.

Customizable Design

They can be tailored to specific liquid types and shipping requirements.

Flexitank Sizes and Dimensions

Flexitanks are tailored to fit 20-foot containers (20′ Dry Standard Containers).

• Internal Container Dimensions: 19.4 ft (L) x 7.7 ft (W) x 7.10 ft (H).
• Flexitank Capacity: Varies by product density (e.g., 21,000 liters for edible oils).

Advantages of Flexitank Container Shipping

▲ Cost Efficiency

Flexitanks significantly lower shipping costs compared to traditional methods. By maximizing payload capacity and reducing packaging material weight, flexitanks save on both shipping and handling expenses.

▲ Easy Installation and Handling

Installation of flexitanks is straightforward and quick, usually taking less than 30 minutes. Their simple design makes loading and unloading efficient, requiring minimal labor and equipment.

▲ Enhanced Safety and Reduced Contamination Risks

Flexitanks reduce the risk of contamination by eliminating intermediate transfers. Each flexitank is new, sterile, and disposable, ensuring product purity and quality.

▲ Environmentally Friendly

Flexitanks are recyclable, significantly reducing packaging waste compared to drums or barrels.

▲ Increased Cargo Volume

Flexitanks can ship up to 40% more cargo compared to drums and 15% more than intermediate bulk containers.

Pro Tip:

It’s crucial to understand that assessing the environmental impact of these bulk liquid transportation methods involves a complex interplay of factors. While flexitanks offer space efficiency during shipping, their single-use nature contributes significantly to plastic waste and resource consumption. Drums, despite being reusable, require cleaning and potential reconditioning, often involving chemical processes and energy usage. ISO tanks, being reusable and robust, generally have a lower environmental impact per use, but their initial manufacturing and transportation also have an environmental footprint to consider.

Disadvantages of Flexitank Container Shipping

▼ Limited to Non-hazardous Liquids

Flexitanks can only transport non-hazardous liquids. Hazardous materials require specialized tank containers due to safety regulations.

▼ Single-use Design

Most flexitanks are single-use, meaning they generate waste despite being recyclable. Repeated purchases are necessary for ongoing shipping needs.

▼ Risk of Leakage

Though rare, improper handling or loading may lead to leaks. Proper training and handling procedures are crucial to prevent such issues.

▼ Handling Challenges

Loading and unloading large volumes require specialized equipment and trained personnel.

▼ Disposal Concerns

Being single-use items, flexitanks must be disposed of responsibly to minimize environmental impact.

Flexitank Safety & Best Practices for Shipping

Preventing Leaks

• Work with certified providers for installation.
• Avoid overfilling (stick to 95% capacity).
• Use containers free of sharp edges or debris.

Compliance Across the Americas

• Ensure transported liquids comply with regional regulations, such as FDA (U.S.), CFIA (Canada), COFEPRIS (Mexico), SENASA (Central & South America), and INVIMA (Colombia).
  
• Verify flexitank certifications, including FDA, Kosher, Halal, and FSSC 22000, to meet food-grade and sanitary requirements.
  
• Comply with local environmental and hazardous material regulations when shipping chemicals or sensitive liquids.
  
• Partner with logistics providers familiar with import/export compliance across North America, Central America, South America, and the Caribbean to avoid delays or penalties.

When to Use Flexitanks (And When Not To)

Ideal For:

• Bulk edible oils, wines, syrups, or non-corrosive chemicals.
• One-way shipments (no return logistics).

Avoid For:

• Hazardous materials (e.g., acids, solvents).
• High-viscosity liquids (e.g., heavy oils) that are hard to pump.

How to Choose a Flexitank Provider

1. Certifications: Look for ISO 9001, FDA, or industry-specific approvals.
2. Experience: Prioritize providers familiar with your shipping routes.
3. Insurance: Ensure they offer insurance coverage on potential leaks.

Why Flexitanks Are Gaining Popularity in North America

• Cross-Border Trade Growth: Increased cross-border trade in the NAFTA/USMCA region boosts demand for efficient liquid transport.
  
• Cost Pressures: Businesses seek cheaper alternatives to ISO tanks and Flexitanks offer a cheaper alternative for one-way or challenging return logistics.
  
• Operational Flexibility and Reduced Logistics Complexities: Flexitanks offer logistical advantages, like easier handling and reduced return shipping costs, which can be attractive despite environmental considerations.
