What People Mean by a 'Food Grade' Tote
When buyers ask for a 'food grade' IBC tote, they usually mean a container whose materials and history make it suitable for contact with food. The inner bottle of a composite tote is made of high-density polyethylene (HDPE), and new bottles from the major manufacturers are generally made from resin intended to be suitable for food contact. Whether a particular tote is appropriate for your food product, though, depends on much more than the plastic it started with.
Responsibility for food safety sits with the business handling the food, not with the container. If you are storing or moving food products, your own food safety plan, your inspector and the product manufacturer's guidance decide what containers are acceptable. Check current regulations with your local authorities and your food safety advisor before choosing containers.
Why Prior Contents Matter Most
For a used tote, the single most important question is what it held before. HDPE can absorb small amounts of some chemicals into the plastic itself, and cleaning the surface does not reliably remove them. That is why a tote that once held industrial chemicals is generally not considered suitable for food use, however clean it looks.
Totes that previously held food products such as vegetable oils, syrups or juice concentrates are the usual candidates for reuse around food or for non-potable water. Even then, ask for the prior contents in writing, check that the valve, gasket and cap are suitable for your product, and follow your own cleaning and sanitizing procedure before filling.
ABC IBC does not arrange totes for food-contact use. If you need containers for food production, buy from a packaging supplier that can document material compliance and prior-use history to the standard your food safety plan requires. Used totes requested through ABC IBC are better suited to uses such as irrigation, livestock water, general storage and projects.
Questions to Ask Any Supplier
Whatever the end use, these questions help you judge a used tote: What did it hold before, and can you put that in writing? When was the bottle made? Has it been cleaned, and how? Is the valve the original, and what is the gasket material? Has the tote been stored outdoors, and for how long?
A supplier who answers clearly and in writing makes it much easier to decide whether a tote fits your application. If a seller cannot tell you what a container held, assume it is not suitable for anything sensitive.
Storage and Handling Basics
Sunlight degrades HDPE over time, causing chalking, yellowing and brittleness, so totes intended for sensitive uses are best stored under cover. Extreme heat and freezing both stress the bottle. Keep caps closed during storage to keep out dust, insects and rainwater.
Check the bottle's manufacture date, which is usually molded into the plastic, and the overall condition of the bottle, cage and valve before each use. Very hot products can soften HDPE, so if your process involves elevated fill temperatures, ask the container manufacturer what the bottle is rated for or consider a stainless steel tank.
