The health benefits of glass go beyond taste. The Food and Drug Administration (FDA) is responsible for food safety in the United States. Glass is the only food packaging material the FDA considers “Generally Recognized as Safe” (GRAS).
The glass melting process transforms raw materials into a new substance whose characteristics are distinct and controlled. It is a “one-way” process since it cannot be reversed and the components cannot be separated once the process is done. Additionally, the FDA accepts that glass is an effective barrier against potential exposure of food products to materials applied on the exterior surface of glass containers. O-I manages any surface-treatment products, like lubricants or decorations, to adhere to FDA, food safety, local, or any other relevant regulations.
