Food grade bulk bags are bags that are made with the intent of using the bulk bags in a food grade facility for the packaging of food products. True food grade bags are manufactured in an AIB or BRC certified facility. Many suppliers say that their bulk bags are food grade, however, in reality they are food grade "ish" bulk bags. The qualifying question for your current supplier is, are your bags made in an AIB or BRC Certified facility? If yes, then they will have no trouble providing a copy of their AIB or BRC Certificate.
