Corrugated original paper machine
Corrugated raw paper is one of the important components of corrugated board. Corrugated paper requires good fiber binding strength, smooth paper surface, good compactness and stiffness, and a certain degree of flexibility to ensure that the made carton has shock and pressure resistance.
Corrugated paper also known as corrugated core paper. Corrugated is corrugated corrugated corrugated in the core of the raw materials paper. It passes. through corrugated machined by heating to 160 ~ 180 C corrugated roller will stare blankly into corrugated paper core paper, paper rolls and sheet. The quantity is 112 ~ 200g/m2. The fibrous tissue is even. The thickness of the paper is consistent. The color is yellow and bright. It has a certain loose thickness. It has high stiffness, ring pressure strength and water absorbance. With natural color broadleaf wood semi – chemical pulp, cold – alkali pulp or natural color alkaline straw pulp or with waste paper pulp, after the dispersion of the pulp, that is, into the circular net multi – cylinder paper machine copy. It is mainly used as corrugated core layer (middle layer) of corrugated paper board and plays an important role in anti-vibration performance of corrugated paper board. It can also be used as separate packaging paper for fragile goods.
There is a jargon in the paper industry. It can be seen that the quality of pulp is important, and the pulping process is also the key quality control point of papermaking. The quality of pulp determines the quality of paper.
