China's carton machinery and equipment development trend

Single-sided corrugated units were introduced in the 1980s and early 1990s to adapt to the needs of small and medium-sized carton enterprises and to replace single-machine manual operation. The current "centralized board making, decentralized box making" pattern of cooperative production within the industry is being implemented around the world, and single-sided corrugated units are bound to be eliminated. Not in front of the production of cardboard, and the use of cardboard production lines to buy cardboard processing carton way.
