Flexi-bags (also called flexi-tanks) offer an alternative to ISO tank containers for shipping oils, juices, wines, food-grade liquids and nonhazardous chemicals across the globe. Flexi bags are usually loaded into 20' food-grade, ISO containers for maritime transport. Sizes range from 16,000 to 26,000 litres. For transport in the US, the materials used in the production of flexi-bags have to meet the US Food and Drug Administration, EU food-grade or German BAG standards. The idea is to isolate the liquid being transported from ambient air to avoid oxidation.
