After the corrugated paper is coated with glue, it is pasted and combined with other corrugated papers. In the process of coating the corrugated paper with glue and then combining it with other corrugated papers, there will be a certain amount of overflow of the corrugated paper, resulting in waste and extra consumption of glue.
