A milk bag is a plastic bag that contains milk. Milk bags are usually stored in a pitcher or jug with one of the corners cut off to allow for pouring.

Why is bagged milk better?

They contain less plastic than a milk jug, causing less environmental harm than milk jugs. Milk bags are more ideal from an environmental standpoint than paper milk cartons or glass milk bottles.

Does America have bagged milk?

And though Americans are all-in on cardboard milk cartons, or the occasional plastic jugs, throughout the rest of the world—from India and Israel to our dear neighbors Canada—milk is sold in plastic bags. America is, in fact, somewhat anomalous for selling its milk in upright containers rather than in plastic bags.
