Do Americans put milk in bags?
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.
Why do milk bags exist?
Bagged milk evangelists argue that pouches use 75 percent less plastic than the average plastic milk jug and are lighter, requiring less energy to ship (the same argument taken with beer in cans versus bottles and paper versus plastic bags). Consequently, the bags more affordable than their bottled competitors.
Is bagged milk only in Canada?
But did you know that bagged milk is also a uniquely Canadian invention? Believe it or not, milk bags have been in Canadian fridges since the 1970s, selling mainly in Ontario, Québec and the Maritimes. Each package contains three un-resealable plastic pouches filled with milk, equaling 4 litres total.
