b: Imitation kraft cardboard. Features: 15-25% wood pulp is hung on the surface, and the rest is OCC; the fiber is shorter and the strength is worse than that of kraft cardboard. The paper surface is smooth, with different degrees of sizing (water absorption ranging from 30-55g/m2), and surface dyeing treatment. Abbreviation: Domestic cattle card.

c: Recycled paper. All composed of OCC, but different from corrugated paper. The surface is 11# or more AOCC noodles and has been dyed). The market is generally called C-grade containerboard, and some are called T paper.
