Milk jugs are a type of bottle that is used to transport milk and other dairy products, typically in the form of cream or sour milk. They can be made from glass, plastic, ceramic, or metal with similar designs but slightly different proportions. How they’re manufactured has been a mystery for years because in North America it’s not easy to find people who actually make them anymore.
Milk jugs are made from a thick plastic that is then cut into small pieces. The pieces are then melted and molded into the shape of a milk jug.
