Today, I will give you an introduction to the types of carton base paper commonly used in printed materials.
1: Corrugated base paper
The national standards are divided into four types: A-level, B-level, C-level, and D-level. Class D corrugated paper is basically eliminated by the market, and few manufacturers buy and use it.
2: Corrugated paper
a: Kraft cardboard (Mika, Eka). Features: long fiber, re-sizing, high physical strength, rough cardboard; pure wood pulp or a small amount of OCC. Abbreviation: imported cattle card.
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 cow cardboard. The paper surface is smooth, sizing in different degrees (water absorption ranging from 30-55g/m2), and surface dyeing treatment. Abbreviation: domestic cattle card.
c: White cardboard. White flour cattle card base, surface bleached wood pulp, the rest is natural or dyed wood pulp. (Russian white, Swedish white card, Finnish white card); white paper (surface bleached wood pulp, the rest is deinked or non-deinked waste paper); coated white paper (white on white, white on gray).
d: Recycled paper. All are composed of OCC, but different from corrugated paper. The surface is AOCC dried noodles above 11# and dyed). The market is generally called C-level boxboard paper, and some are called T paper.
