Tetra Pak is a special kind of packaging that keeps food and drinks safe for us to eat and drink. It looks like a rectangle that has been folded and glued together, like a cardboard box. But it's not just made of cardboard - it's made of a few different layers that work together to protect what's inside.
The inside layer is made of plastic that won't let any air in, so the food or drink inside can stay fresh for a long time. The next layer is made of aluminum, which stops light and air from getting in. That way, things don't go bad too quickly or get spoiled. Then there's another layer of plastic on the outside that makes the package strong and easy to handle.
Tetra Pak is used for lots of different kinds of packaged foods and drinks, like juice boxes, soup cartons, and even milk cartons. The great thing about Tetra Pak is that it's easy to recycle. You can take the package to a recycling center and they will make new things out of it, like paper products or even new Tetra Paks!
