What’s the difference between a “core” and a “tube”?
Paper cores and paper tubes are structurally the same, how each is used determines what it’s called. A paper tube is called a “core” when something is wrapped or wound around it. Think of a roll of tape, paper towels, or holiday wrapping paper – these are all products wrapped around a paper core. A paper tube is called a “tube” when something is put inside of it. Think of posters, cosmetics, and Pringles – these products are all packaged inside of a paper tube.
