Ecommerce boxes are produced with corrugated boards for the outer sections, using either recycled material (called “Test”) or virgin material (called “Kraft”). These boards come in different gsm thicknesses, for example; 150gsm, 180gsm and 200gsm. They can be brown on both sides (K/K), white both sides (WK/WK), or a combination of the two. The boards are then mounted onto a corrugated flute material which can be single or double wall; common flutes include B flute and E flute.
