‘SPF’ for milk packages certifies that nutrients are protected
A logo signifies that the packaging has been audited for its ability to screen light.
Think of it as an SPF for dairy packaging. Just as sun screens promote a skin protection factor, The Chemours Co. is promoting an LPF, or light protection factor, to appear on the front of milk bottles. The LPF number would communicate to consumers that nutritional components in milk, especially riboflavin, have not be degraded by light as the package sits on a retailer’s shelf.
The LPF would assure consumers that the milk they are buying contains all the nutrition they expect.
