Corrugated base paper is one of the important components in the production of corrugated board

Corrugated base paper is one of the important components in the production of corrugated board. Corrugated base paper requires good fiber bonding strength, smooth paper surface, good tightness and stiffness, and requires certain elasticity to ensure that the produced carton has shock resistance and pressure resistance.

Corrugated base paper is also called corrugated core paper. It is the raw material used to form the corrugated core of corrugated cardboard. It is processed by a corrugating machine, and corrugated paper is corrugated by a corrugating roller heated to 160-180 ° C to form corrugated paper (corrugating paper). There are roll paper and flat paper. Gsm is 112～200g/m2. The fibrous is uniform. The paper thickness is the same. Bright yellow in color. There is a certain bulk. It has high stiffness, ring compressive strength and water absorption, and excellent fit adaptability. It is made of natural hardwood semi-chemical pulp, cold alkali pulp or natural alkali straw pulp or mixed with waste paper pulp. It is mainly used as the corrugated core layer (middle layer) of corrugated cardboard, which plays an important role in the shockproof performance of corrugated cardboard. It can also be used alone as a wrapping paper for fragile items.
