Why is honeycomb paperboard a more sustainable option? The surface paper materials of honeycomb cardboard are generally divided into cattle card, vermicelli, and yarn tube, and the core paper is generally divided into high-strength corrugated paper, Powa, and C-level vermicelli. The honeycomb aperture is usually distinguished by the unilateral length of the honeycomb paper core hexagon, which is generally 4, 6, 8, 10, 12, and 14 mm in length.
