Don’t Flatten Cartons
The sorting machinery at processing facilities is programmed to recognize a carton’s shape. Keep a carton three-dimensional to increase its chances of being sorted properly.
How to Recognize Tetra Pak Cartons
A plastic Tetra Pak carton is smooth and glossy with a shiny metallic lining on its inside. These cartons are shelf stable until opened and usually rectangular with sides that are folded down. For some cartons, the Tetra Pak logo can be found on the bottom side of the item.
Refrigerated Cartons Are Different
Refrigerated cartons (such as milk and juice) contain more paper than a Tetra Pak carton and don’t keep their contents fresh unless refrigerated. They also tend to have pointed tops. Learn how to dispose of refrigerated cartons.
