Every carton box has 2 parts:
– One is liner board: Linerboard is the flat facing that adheres to the medium
– Two is the medium: The medium is the wavy, fluted paper in between the liners. Flute helps to increase the bearing capacity for carton boxes. There are many different types of flutes: E flute , C flute, B flute, A flute, AB flute,… depending on what is stored inside the carton box and according to the customer’s requirements.

The following illustrations demonstrate four types of combined board:
