A Tetra Brik is a special kind of container that helps to keep food and drinks safe and fresh. It is made out of materials that are safe to use with food, like cardboard and plastic.
The cardboard part of the Tetra Brik is called paperboard, and it gives the container its shape. The plastic part of the Tetra Brik helps to keep the food and drinks inside from spilling or leaking out.
When you want to use a Tetra Brik, you first need to open it up. There is a little corner that you peel up, and then you can pour out whatever is inside.
Tetra Brik containers are used for all kinds of different things. You may have seen them holding milk, juice, soup, or even pet food! They are great for transportation and storage because they keep things fresh and are easy to handle and dispose of.
