A cardboard box is basically made up of a flute (made up of recycled paper), sandwiched between two liners. It is now very common for these liners to also be made up of a considerable proportion of recycled content, sourced from old cardboard or other sources of second hand paper.

When manufacturing boxes we talk about two different types of liners, this is the material that lies on top and beneath the fluting and creates a corrugated board. Typically, cardboard boxes have a test paper inner liner, and a Kraft paper outer. This is because Kraft is better quality than test, and has a smoother finish so that it can be easily printed on. Kraft also has the benefit of being more resistant to water pe*******on which is an added benefit of using it for the outer face.
