Corrugated cardboard is a multi-layered adhesive, which consists of at least one layer of wavy core paper sandwich (commonly known as "Pit Zhang", "Corrugated Paper", "Corrugated Core Paper", "Corrugated Paper Core", "Corrugated Paper") and a layer. Cardboard (also known as "box paper", "box cardboard"). It has a high mechanical strength and can withstand collisions and falls during handling. The actual performance of corrugated boxes depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.
It is made of at least one layer of corrugated paper and a layer of cardboard paper (also called cardboard), which has good elasticity and extensibility. Mainly used in the manufacture of carton, carton sandwiches and other packaging materials for fragile goods. The soil paper pulp and waste paper are beaten to make a raw paperboard similar to yellow paperboard, and then mechanically processed to be rolled into a corrugated shape, and then bonded on the surface with an adhesive such as sodium silicate and cardboard paper. The corrugated corrugated corrugated cardboard looks like a connected arched door, which is juxtaposed in a row and supports each other to form a triangular structure. It has good mechanical strength, can withstand a certain pressure from the plane, and is rich in elasticity and cushioning. It has good effect; it can be made into liners or containers of various shapes and sizes according to needs, which is simpler and faster than plastic buffer materials; it is less affected by temperature, has good light-shielding property, is not affected by light, and is generally affected by humidity. However, it should not be used for a long time in a humid environment, which will affect its strength.
With the continuous development of the times, the continuous updating of production technology and equipment, the more sophisticated use of equipment technology and the more detailed market demand, the demand for corrugated board is expanding with a very considerable geometric multiple. The prospects for development seem to be bright and the future is boundless. However, in the increasingly fierce market competition, science and technology are constantly updated, new packaging materials are constantly being developed. Today, corrugated paperboard wants to maintain its position as a "one brother" in packaging materials, in the development of technical equipment, improvement of quality performance. And the expansion of product categories and other aspects must be further improved and developed.
