Corrugated carton is made of corrugated paper. Its weight is light, the structure performance is good. Because of the special structure of corrugated board, 60-70% of the volume is empty. Its internal corrugated structure is similar to arch structure, it can play an anti-impact, shock absorption role, with good mechanical properties, can avoid the packaging received collision and impact. At the same time also has moisture-proof, heat dissipation, easy to operate and so on. Low transport costs, easy to achieve the mechanization and automation of packaging transport.
