[0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of boxboard. It has good elasticity and extensibility and is mainly used to make cartons, cardboard sandwiches and other packaging materials for fragile goods. Corrugated cardboard is mainly made of indigenous straw pulp and waste paper through pulping to make raw cardboard similar to yellow cardboard, which is then machined and rolled into a corrugated shape. Then, it is bonded to the boxboard with adhesives such as sodium silicate on its surface. With the development of society and the advancement of science and technology, corrugated boxes have also developed rapidly. Corrugated boxes are green and environmentally friendly products, and have the advantages of environmental protection and easy loading and unloading and transportation, and are widely recognized and used.
