Butcher paper is a big sheet of paper that butchers use to wrap meat. Imagine if you need to wrap up a big present like a bike, you would need a big sheet of wrapping paper to cover it all up. Butcher paper is like that, but it's used for food instead of presents.
But why do we need to wrap meat in paper? Well, when you buy meat from the grocery store, it's usually wrapped in plastic. But sometimes, the plastic can make the meat go bad faster because it doesn't let air flow around it. When you wrap meat in paper, it lets air flow around it and keeps it fresher for longer.
Butcher paper is also really great for other things too! You can draw on it, use it to cover tables for messy projects, or even use it for wrapping presents if you want a more rustic look. Overall, butcher paper is versatile and useful for many different things.
