Corrugated board is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly called as "hole paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of paper board (also called as "box board paper" or "box paper board"). It has high mechanical strength and can resist collision and falling in the process of transportation. The actual performance of a corrugated box depends on three factors: the nature of the core paper and paperboard and the structure of the carton itself. Corrugated board is also called corrugated board. Is formed by bonding at least one layer of corrugated paper and one layer of boxboard (also called boxboard), and has better elasticity and extensibility. The method is mainly used for manufacturing cartons, the sandwich of the cartons and other packaging materials of fragile commodities. The raw paper board similar to yellow paper board is made up by using straw pulp of earth method and waste paper through pulping, then is mechanically processed and rolled into corrugated form, then on its surface the adhesive of sodium silicate is used to adhere it to the cardboard paper so as to obtain the invented product. The corrugated corrugations of the corrugated board are like arch doors which are connected one by one, are mutually parallel to form a row and mutually support to form a triangular structure body, so that the corrugated board has better mechanical strength, can bear certain pressure from a plane, is rich in elasticity and has good buffering effect; the cushion can be made into liners or containers with various shapes and sizes according to requirements, and is simpler, more convenient and faster than plastic buffer materials; the coating is slightly influenced by temperature, has good light-shielding property, is not deteriorated by illumination, is generally slightly influenced by humidity, but is not suitable for long-term use in an environment with high humidity, and influences the strength of the coating.

The corrugated board can reduce white pollution, obtain good environmental protection effect, and meet the requirements of sustainable development of the current society. The design scheme can also save the use of raw materials, wherein the corrugated raw paper materials used most for manufacturing the corrugated board are made of paper pulp fibers or paper sludge obtained after recycling the paper making sewage, so that the effect of recycling waste resources is achieved, the production cost is saved, and a better environment-friendly effect is also achieved.
