Flexitanks For Used Cooking Oil

Flexitanks—also referred to as flexibags, collapsible tanks, or bladders are flexible bags designed to fit inside a 20-foot shipping container, converting them into bulk liquid transportation units. They offer a superior alternative to ISO tank containers and drums for shipping bulk liquids such as used cooking oil.

For the transportation of used cooking oils, a flexitank offers a superior alternative to other bulk liquid shipping containers such as ISO tanks and barrels.

With increasing regulations to meet and a high importance on sustainability, food businesses are increasingly looking for innovative and good value alternatives for ways in which they can store and transport their used cooking oils. Using flexitanks for used cooking oil allows for more efficient use of resources. For example, it takes less time and less labour and is a more convenient alternative to ISO tanks and barrels. Not only are flexitanks more convenient, they are also much more cost-efficient. Below we list the features and benefits of using flexitanks for used cooking oil.

Benefits of using Flexitanks for Used Cooking Oil

  1. Reduce Your Carbon Footprint with Flexitanks

    Not only are flexitanks more economically viable, they are a more sustainable option for bulk shipping your used cooking oils. Our re-usable flexitank containers allow for zero waste in shipping – SIA Flexitanks can be re-used and recycled. The SIA Global Flexi-Max, for example, is made from 100% virgin VLDPE polyethylene which when recycled, is re-processed into pellets which are then used to manufacture new items.

    Using flexitanks when shipping edible oils is one of the quickest and easiest ways to reduce the carbon footprint of the transport process allowing higher volumes of liquid to be shipped at one time.

    SIA Flexitanks are driven by a global commitment to sustainable logistics and fair trade.  Our commitment includes bringing logistics technologies to manufacturers and producers that provide them with access to the new markets and more trading opportunities while using fewer resources.

  2. Increase Payloads with Flexitanks

    Using Flexitanks can increase your payload and therefore your profits as Flexitanks offer 15% more per payload than totes and 40% more payload than drums. In addition to increasing payloads, flexitanks allow you to diversify your customer portfolio to attract customers buying smaller quantities. And you can diversify your revenue streams because with regular weekly sailing schedules, you can have regular shipments and thus, regular payments.

  3. Cost-Effective Transport

    The lighter weight and transverse stacking capabilities of Flexitanks save truckers an average of $41,000 per trip compared to 340 HDPE barrels. That’s where the value in using a Flexitank originates: less space that can hold up to 6,500 gallons worth of product, and the option for transverse bulk liquid stacking instead of palletizing and linearizing 50-foot ISO tanks. Without the use of Flexitanks for Edible Oils, shipping costs can become exorbitant. Implementing Flexitanks into everyday shipping, costs can be lowered or eliminated completely thus allowing for further profit or product transportation expansion.
