[0002] Corrugated paper refers to a board-shaped material formed by gluing noodle paper and corrugated paper formed by corrugating rollers. The paperboard core is made into corrugated paperboard through certain processes such as pulping, starch paste preparation, pressure forming, gluing, drying, cutting, and stacking. Corrugated paper is usually divided into two categories: single corrugated paperboard and double corrugated paperboard. Corrugated paper has many advantages, such as low production cost, light weight, low processing difficulty, high strength, excellent printing adaptability, convenient storage and transportation, etc. It is also easy to recycle and reuse, in line with the concept of environmental protection.
