Absorption of vacuum outside G-type corrugating roller
China's first pair of 1250mm vacuum-extraction G-rolls was formally put into production in Shanghai. The roll was designed and manufactured by Wujin Haili Roller Co., Ltd. G-type corrugated roll corrugated board, compared with the same weight of folding board, has a better stacking strength and shock absorption performance, can save packaging materials, reduce shipping costs, and can be printed directly on the offset press. The promotion of the use of G-type corrugated board meets the requirements of international environmental protection. Experts predict that it will replace 10% of the cardboard market in the next five years.
