Flexi Tank

Flexible Liquid Tanks

The Flexi Tank is one the most economical forms of bulk liquid transportation. This system uses a flexible tank and places it inside a 20 foot transportation container. This container (filled with any non hazardous liquid) is then shipped to your designated location.

Standard flexitanks can store up to 24,000 liters (or approximately 6,340 gallons) of liquid for transportation. Saving you in costs, these large capacity storage tanks are shipped to your loading dock folded up and empty. This minimizes freight costs to your location while still giving you the necessary liquid storage capacity.

Regardless of your tank material or application, all flexi tanks require care in handling. Each 20 foot container used for the storage of these materials must be prepared and ready to support this kind of storage tank. Preparation materials can include 125 ft. of single face corrugated paper, bulkhead set, and optional envelope liner. Most of the these materials can be purchased locally.
